Ford 7.3L Power Stroke (1999-2003) :: Loud Grinding Type Noise From The Top Of Engine

This started yesterday. A Loud grinding type noise from the top of the engine. As soon as I touch the throttle the noise goes away. I checked the pulleys and TC and everything checks out. Sounds like it's coming from the HPOP gear area like a gear train noise. Maybe the additional oil pressure has something to do with the HPOP inside getting quiet.

Ford 7.3L Power Stroke (1999-2003) :: Low Speed Noise - Rattle / Grinding When Braking

The noise is somewhere between a tin rattle and a bearing grinding heard most when braking but constant under say 10 mph. We have not been able to pinpoint where exactly it is coming from but I believe it is front drivers side.(but really could be anywhere) it is not dependent on rpm, nor gear or clutch engagement, Nor hubs engaged or disengaged.

The drives side front hub, rear hubs' bearings(races and seals) have been replaced. I have the passenger side front hub to do as well, just haven't gotten to it yet and it doesn't seem bad. we are all stumped on what it is. It seems to relate to the rotating assembly though as it seems to change with speed. it almost seems like tire rub, but there is no scaring or marks of any sort anywhere for it.

Vehicle is a e99 f250 short bed ext cab. open diff if it makes any difference. My next thought after the hub is pinion bearing? Could it be something to do with abs? say the truck is 4 wheel abs but the fronts are disconnected (trying to figure out if it is 4wabs as it appears to have connectors, but the original hubs did not have the hole for the sensors. no abs light comes on, but that could be a bad bulb too)

What we have found is hubs locked or unlocked, 4wd engaged or disengaged, and happens at right around 16 mph, braking, accelerating, clutch in or out, in gear or in neutral. All 4 corners have new bearings. We have found 2 things, 1 is the track bar bushings are shot (don't think this is the source of the noise but could be wrong and i will be replacing those..once I have money in again.. 2 the passenger side leaf spring when wacked with your hand makes a different sound than the drivers side.( could be a matter of different loads, but figured worth noting)

There are 2 noises, the first is the noise we hear, the second is one that i found when doing the noise reduction (loud meaty tires you cant hear the noise in the audio without reduction) I think that that was one of the hubs, or maybe the brakes, I am unsure, but it happens at different locations in the video.

Ford 7.3L Power Stroke (1999-2003) :: 2001 - Slight Whine / Grinding Noise Only In First And Reverse

I have a 2001 f 350 7.3 diesel r 400 tranny 320000 miles. . Im having transmission issues. It makes a slight whine/ grinding noise only in first And reverse. And it surges. Sometimes its fine though to. Check engine light came on. Only codes i get are #4 glow plug out and a low boost pressure. Checked boost before fixin Running fine at the normal about 20 psi. ive read a bad or dirty map or iat sensor can cause transmission issues along with the low boost error code. But in my experience and some reading it sounds like a stall converter.

Ford 7.3L Power Stroke (1999-2003) :: Grinding And Metal Chewing Sound Coming From Front Axle Or Close The Wheel Hubs

I have 1999 F350 7.3 Crew Cab 4WD. I took it on a 4 hours trip towing a trailer to haul a small tractor on it. after 3 hours of driving, I started hearing grinding and metal chewing sound coming from the front axle or close the wheel hubs. It was awful, terrible, ... you name it!!! I had to continue or I will lose the tractor I paid for already. The sound was coming for 1-2 seconds each 500 feet or so. It never stopped or changed. I pulled over to see what's going on and found the following:

1. Left shock is leaking badly
2. Right locking hub is gone (not sure if the truck had one before). I bought this truck last year, but I never had to use 4x4 and I know the 4x4 motor by the transfer case is missing and the nipple on the transfer case is set to the 2wd position so the front drive-shaft does not turn.

I took the front shock off and continued to drive without it, the noise did not go away.

I pulled over again and this time I noticed that the dust cover on each end of the front axle is missing too. I have never worked on these axles before, but I jacked one side, and sure enough, gear oil was leaking from the other side. I took the plug off the front differential and stuck my finger in it. I felt a creamy brown-greenish stuff in the differential. The consistency is like mayonnaise or thin peanut butter. I put the plug back on and went to pick up the tractor because I did not want to miss it fooling around with the truck on the highway.

The truck made it there and back (almost 5 hours total after the break down). The sound never stopped every 500 to 1000 ft.

After getting home safely, I took the other locking hub off, and took it for a test drive. I did not hear the noise, but now my right brakes are locking.

I took of the wheels and saw that the retaining snap ring (C clip) for the front axle on the right side came off by hand. I took the washers behind it off. Took the calipers and brackets off. I have never done front axle rebuild. I am not sure what has been damaged and what's still good.

Right of the bat, I know, at least, I need 2 shocks, one brake caliper and pads.

My questions are:
1. Is it possible to take the front axles off on both sides and make it 2wd for now until I have the money to rebuild the axle?
2. Could I use the same hubs? or they are most likely damaged and how to tell?
3. How to tell if the differential is damaged/needs rebuilding?
4. How to tell if the axles/spindles are damaged?
5. Is there a step by step tutorial to rebuild the axle with all seals, bearings, ...etc? How hard is the job for a hobbyist? I do most of my repairs myself, and I was lucky at 36 years old, I never had to rebuild a differential.
6. What else I might have damaged in the process of driving it that long with the noise? How do I tell if I did?

Ford 7.3L Power Stroke (1999-2003) :: Loud Gear Meshing Like Grinding Noise - Delayed Hard Shift 2 - 3

I have an early 99 F250 4x4 7.3L..... 4R100....

Brief history, a while back on way home from work I let off of the accelerator and had a loud gear meshing like grinding noise, got back on the accelerator and went away, let off and back, so I quickly stopped and pulled over, went through the gears and reverse, everything seemed ok,??? went on my way, got home parked the truck and went about my evening. came out next day to leave and truck wouldn't move in reverse, forward but not reverse. long story short I was told that the snap ring internally probably came out, I have heard of this being a big issue with these, so I set up for it to be rebuilt, got it back and installed and still same issue, what the crap so I ended up having to pull it back out and amongst my own trouble shooting I found the simple issue and was the nylon riders on the 4hi/4low shifter fork were completely gone and allowing the planetary group to free float in and out of 4x4 neutral!!! NOW on to the issue at hand. so far only thing has been done is rebuilt and those fork riders replaced.

now I can move but 2-3 upshift under a load(more noticeable) has a delay going from 2nd to 3rd and under a load it hits hard. I talked to the guy that rebuilt it and he said that the rebuild kits don't always the right springs for the valve body and causes shift issues, so he talked me into the shift corrector kit which I researched and did see what he was saying, so had that done and still no better, still does it, however, it does shift into the gear softer but didn't fix the delay or the hitting hard when it did finally go into 3rd.

After being forced to drive it that way I have since determined that what it happening is it is coming out of 2nd with a second and half pause and then shifting into 3rd, the hard shift comes in to play because during the delay the torque convertor is locking up making it a direct drive like popping the clutch on a standard!!!

I just swapped out the sol pack and I heard from a youtube video that the bolt next to the 2-3 upshift valve on the valve body could be to tight and making a sticky valve, so I re-torqued all the bolts and nuts put all back together and test drive proved to be worse, I now have same issue in all upshifts. all hit hard now, I am at a loss and don't know where to go from here, I can only imaging the sol pack is causing this but I have yet put my org one back in to see... oh and I found two bolts on the accumulator stripped and found one non torqued bolt on the main valve body!!

Ford 6.0L Power Stroke Diesel :: Grinding Noise From Front End

I recently replaced the front wheel hub and upper and lower ball joints on the the driver side of my 2004 f250 CC SB 6.0 fx4. Now when I put into 4 wheel drive I get a grinding noise that sounds like a worn out break pad from that side only. It didn't do it before and it only happens in 4x4. I have replaced the wheel hubs before and it was fine. Also The needle bearing race on the axle is good.

Ford 7.3L Power Stroke (1999-2003) :: Growl Noise In Front End Comes And Goes

Been trying to track down a noise in the front end. Got a growl and what sounds like a big cat scratching its nails on a metal plate. The metal sound comes and goes, but the growl is always present at one level or another. It sounded like it was coming from the driver's side. I jacked the truck and checked everything on that side and it seemed tight. It was all replaced about two years ago. I then started looking around and found the sway bar links were shot along with the bushings. I then jacked up the passenger's side and checked that.

Should have done this first as it was pulling to the right and not the left. The wheel was hard to rotate and stopped rotating as soon as I stopped forcing it. It was making a growling noise, but not nearly as loud as when the truck was rolling down the road. It also had a bit of play that I tracked down to the hub assembly. The ball joints and u-joints were tight with no play at all. The dust seal that should be on the axle was gone and the hub seal looked beat. Tie rod ends all seemed good. Ordering part now. My question is there anything else I should look at?

Ford 7.3L Power Stroke (1999-2003) :: Sneaky Front End Noise

With the cold weather lately, I've noticed my truck has developed a new noise from the front axle. It only does it when the truck has sat for a few hours, is completely cold (below 30*), and the hubs are locked. It will only make the noise going forward. I've eliminated brakes and hub assembly as the source since the noise is only made when the hubs are locked, or when the shifter is in 4x4 with the hubs unlocked.

Its a squeak, squeak, squeak noise that seems to be with every revolution of the tire and it goes away after driving 50-100 feet. All the u-joints are tight and I can't make the noise spinning the front driveshaft by hand. The brakes have 9000 miles on them with hawk pads and powerstop cryo rotors. Neither hub assembly has play and all the ball joints are tight. I do leave the hubs locked almost year round, so there's probably a good 40k on them.

I was thinking of throwing some new u-joints on and seeing what happened, but I'm guessing the whole axle shaft has to get pulled to do the ones at the steering knuckles?

Ford 7.3L Power Stroke (1999-2003) :: 2001 - Vibration / Noise Up Front

I have seen a number of post about front end vibs associated with steering and braking. I have had a hard time finding these posts and decide to post my vib/noise accompanied when brake and steering applied.

I too have a vib/noise coming from the front at low speed braking and turning (mostly parking lots and such).

About 5-6 months ago (around 90k miles) I noticed a high squeal at high rpms. I thought it had something to do with the belt so one day while driving up the grapevine pass (I-5), under high rpm, I turned the AC on. The squeal went away, I turn the AC off the squeal came back, I was pretty sure it was the belt and hopefully not the AC compressor.

10k miles later, I finally got to changing the serp belt. After I changed the belt, I immediately heard a rough vibration noise when braking and then when PS is under strain. It seams like it comes and goes when it wanted to, but now its always under the low speed parking lot conditions. Sometimes the vibration can be felt in the floorboards.

I haven't gotten to fix'n it yet lol... as I don't know what the problem is. I'm finding it hard to believe that a serp belt could be the cause of vib/noise when braking/low speed turning. One thing for sure, the vib/noise instantly occurred when I changed the serpentine belt. What might be going on here?

Ford 7.3L Power Stroke (1999-2003) :: Slight Vibration And Front End Noise

Recently I have a vibration that I can feel slightly through the steering wheel. If I'm driving down the highway doing 70mph + I have a noise coming from the front end. Also while driving let's say 40mph and below and I let off the pedal to slow down I can here a vibration in the front that kind of sounds like a small Jake break. And when going over anything bumpy I hear like a popping metal sound. This popping sound has been going on for a long time and still can't figure it out. I replaced all my shocks thinking my old set was bottoming out. Nope, still have the same problem.

I jacked up the front end yesterday and checked for movement top and bottom and side to side thinking maybe the wheel bearings or ball joints were going. Everything is solid. Spun the wheels and no noise, no grinding, nothing. I can't figure it out. I have not removed the wheels to check and see if a caliper is loose. I will be checking that next. I did notice while looking around that I can push up on my pitman arm on the steering box. It's not a huge amount of movement but I can still move it. I can also see teeth marks between the box and the arm, not sure if that is normal or not. When I do move it up and down it sounds a lot like that metal popping sound I have been hearing. So, I know this is a lot.

Ford 7.3L Power Stroke (1999-2003) :: 2001 F350 - Low Grind Like Noise Coming From Right Front

Now down to the question in hand. I have a 2001 f350 4x4 with7.3 diesel...I have recently noticed a low grind like noise coming from the right front. I have troubled shot the issue and I am 100% sure it is the wheel hub assembly. Did I mention I am running 37x13.50 tires..and now it is the hubs...and they are the original hubs.. My question is every thing I look for shows ABS is on my truck... I look at the hub and don't see it.. so with the Dana 60 front does it have ABS or not? Also, should I go motorcraft, Timken or moog wheel hubs?

Ford 7.3L Power Stroke (1999-2003) :: Loud And Vibrating Noise Form Front Left?

I've got a loud, intermittent, swooshing, vibrating noise from the front left wheel area at highway speeds. I put a camera down there and saw that when there was noise, the front driveshaft and front left halfshaft were spinning. When they stopped spinning on their own, the noise stopped. Hubs are Warn Premium (gold) and unlocked. Unit bearing already replaced. What could it be?

Ford 7.3L Power Stroke (1999-2003) :: Loud Noise From Front Seats While Accelerating Or Decelerating?

when i accelerate or let off the peddle I hear and aloud thug or dull bang. I've checked and greased all the u joints. Disconnected the carrier bearing and separated the drive shaft and greased it up. Still get the noise I have very little play in the carrier bearing but I don't think that's the problem. It sounds to me like might be at the transmission. What do y'all think it is?

Ford 7.3L Power Stroke (1999-2003) :: Noise Coming From Front Left Area Increases With Speed?

Thats the sound coming from I think the front left area and the rate is proportional to speed. It only occurs at slow speed from about 5 to 15 mph and it seems to only occur for about 30% of each rotation. I plan to jack it up and check tire wobble or if the sound occurs during free spin. Any other things to check?

Ford 7.3L Power Stroke (1999-2003) :: Front Wheel Making Screeching Noise - Lost All Steering?

Ok, so I leave the fire station this morning headed home and my steering felt weird. About 1/2 mile from home I hit a bump and my drivers side front wheel started making a screeching noise. I stopped and looked out the window and it appeared fine. I limped home and as I pull in the driveway, I lost all my steering. I look under the truck and this is what I found.

Not sure what to do. This is my daily driver and neither of my 2 mechanic friends will answer their phones.

So I'm attempting to track down a grinding/vibration I'm getting only in 4x4. Mechanic checked the axle and front drive shaft u-joints and he said they're all fine. It's not the wheel bearing they are both fine, one is brand new. What to check next or how?

Ford 7.3L Power Stroke (1999-2003) :: Light Metal Rubbing Noise Coming From Front Left Wheel

I have developed a sounds that sounds like metal on metal. Not a grinding but more of a "swish swish swish" light metal rubbing when the truck has been running a mile or two. I can barely hear it over the radio but its very noticeable when the window is down. It is not affected by the pressing the brakes and it gets louder and faster in direct portion to speed. It will occasionally leave and start right back up. I touched the front rim around the hub and it was hotter than I wanted to hold onto. It didn't burn but it was hot. It was 105 degrees that day. Here is what I have done.

I replaced that front hub in 2010 and probably have 50K miles on it. I did the 3-9 test and there was no noticeable play. I spun the hub and while it seems to spin ok it does seem a little dry.... I will pull it tomorrow and see what it looks like.

I pulled the calipers off and the brakes pads are at half way and there is no burnt smell. I spun the rotor and it seemed flat and straight. I do have a small tiny lip all the way around them on both sides but I figured that's normal with 265K. I pulled the pins and they were dry but they didn't seem to be sticking. I cleaned them up with the boots and am going to replace them when I get some brake grease tomorrow. I have not looked real hard at the caliper but I plan on pressing that with a C-Clamp tomorrow to check it. Since the rotors and pads looked OK, I assumed there was not a stuck caliper although haven't ruled it out. The axle behind the hub seem to spin freely before I removed all this stuff and the hubs are not locked.

I think I covered it all .. I also thought it could be a rock or stick but nothing came out of my caliper or rotor when I took them off ..
