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 7.3L Power Stroke (1999-2003) :: Bump / Thump Type Noise When Start From A Dead Stop
For probably years, I have had a bump, thump type noise when I start from a dead stop... say at a red light. I had it in my head, maybe there was that much slop in the drive train... as old truck is over 400,000 miles.
Yesterday, I rebuilt the driver's side axle, bearing,seals, new hub...the works.. I heard that noise again later... and my thoughts were, I did all that work and I'm going to find a lower/upper ball joint is bad, although I did look at them and thought they were fine during the rebuild.
Had my wife get in truck.... and swing wheel back & forth... so maybe I could see what was loose.. or making noise.
I was shocked... just something I never thought of looking at. The u-bolts holding the leaf springs were loose... the whole axle was shifting back and forth on the axle. I've never touched those bolts....
Ford 7.3L Power Stroke (1999-2003) :: 4x4 Grinding Noise From Front?
My truck has been doing great over here in Germany, and I want it to stay that way lol. I know the snow is fast approaching here and figured I should test my 4x4(I usually do monthly anyway). After switching to 4-high and making the first turn in the open parking lot, I heard a lot of popping and grinding from the front end. I straightened the wheel and out and the grinding /popping continued.
I stopped, got out of the truck to try and lock the hubs to see if that would fix the issue. turns out the passenger side hub is locked up tight. I couldnt move it by hand and wasnt about to attempt to move it with added leverage.
What this could be? maybe a collapsed vacuum hose? but then I should still be able to manually turn my I hubs I would think.
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.

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?

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?
View 2 RepliesFord 7.3L Power Stroke (1999-2003) :: Loud Knocking Noise - Failed Cylinder 8 Contribution Test
My truck is currently stock and recently started making a knocking noise louder than it usually does. I researched and have found the injectors can make a knocking noise when not performing correctly. I took it to a local shop who hooked it up to a snap on scan tool and ran some tests. It passed the Buzz test but continually failed the contribution test on cylinder 8. I'm going to go home and remove valve cover and unclip the injector to see if the noise goes away. I'm sure hoping it does as an injector by the looks of things is definitely the cheaper option. I'm scared because if I was listening to a gas powered truck and heard the sound my trucks making I would assume it was a lower end noise. My truck only has 148,000 miles....

Just over 7000 miles all of a sudden I got this loud grinding noise in the rear end like a brake locked up. Pulled into a parking lot. Don't think it's brakes. Put the truck in reverse it got even louder for a second then it quieted down after that. Naturally this happened on a Saturday.

I have a 2003 Camry XLE L4, and there is a grinding type noise when I turn the steering wheel at low to intermediate speeds, and when I go over a bump. I can also produce the noise when the car is parked and I bounce the driver's side up and down by placing my hands on the left fender. The struts, steering rack, and CV axels are all new. Also when the car is cold, turning the steering wheel produces a squeak (a different noise) from just behind the steering wheel.

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?
View 10 RepliesSubaru - Outback :: 1997 - Loud Gurgling Type Engine Noise
I bought this Subaru used with 350 000 km's on it,and I haven't added that many kilometers to it yet at all. For some reason whenever I drive on the highway and get my speed up to about 120 the front left part of the car (somewhere underneath the hood I believe) starts to make a loud gurgling type of noise. I know that the suspension on that front left tire is missing, but I don't feel the rumbling on my steering wheel and I don't think it's coming from there.

Moving my worldly goods from California to Oklahoma in a rented 26' box truck with my wife following in our '02 F350 loaded to the gills with my lathe, mill, air compressor, weld and assorted machinery. Just west of Deming NM it started to blow lots of white smoke and down on power. Some rattling noises from the engine when throttled up & won't reach 3000RPM.
Had it towed to an impound yard for storage. Plan on sending a flat bed to pick it up when we get to Tulsa.
Any experience with a tilt back trailer capable of loading & transporting this truck that weighs around 17,000 pounds? My plan is to continue on to Tulsa & make arrangements from there.

It has a lost of engine coolant. The oil is 100% clean with no signs of Coolant. No chocolate milk effect. Also it makes a Odd thumping noise at idle. I think it is coming from the Exhaust Manifold.
