Ford 7.3L Power Stroke (1999-2003) :: Grinding When Hubs Are Locked
Warn Premiums, installed them and now the 4x4 is engaging, but still have a grinding issue. When the hubs are locked and the switch is in 2 wheel drive, the frond end is grinding, if I switch it to 4 hi, the grinding goes away.

I'm getting a sound every now and then of what sounds like i'm running over rumble strips on the side of the highway. I'm guessing it's the trans grinding. Any thoughts?

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) :: Little Vibration From 42 - 45 Mph
I'll get right into it, when I put the mud grips on my truck it always had a little vibration from 42-45 mph and it wasn't to bad. Recently from 30-65 I have a bad shuddering vibration that I get mainly in the steering wheel but I also feel it everywhere else and can see it on the mirrors. Well the front sway bar has a bushing that is broken. But also I notice recently at low speeds from my rear drivers side tire there is a noise that isn't right, maybe a bad bearing? I have a long list of stuff I gotta do on the truck and I just want to stop the Shake so I can get to everything else.

As I'm cruising once I hit about 50mph I start getting a vibration in the peddles and floor board. It's not real bad but noticeable for sure. When I hit 70mph it's worse and the truck even sounds like it's vibrating. As soon as I let off the peddle and coast everything is golden.. Smooth.. So it seems to be a problem only under power..
A little back story : About a year ago I was getting bad vibration and loosing power. I put it in the shop and the mechanic said the filter or screen in the gas tank was clogged so he cleaned it. I went to Korea for a year so the truck sat in government storage for a year. When I got it back in March I put in back in the shop to have the front passenger side hub replaced.
I don't know if any of that has to do with the vibration I'm getting now.

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.

Am looking into buying a new transfer case (TC), and one web-site indicated there were 2 different automatic transmissions; Manual vs electronic -shift? So some TC's for 2000 AT's would not work? I found one (used) that was from a 2002.
My truck came to a grinding halt yesterday and I believe the TC. I had been hearing noise for a while and had been in the process of eliminating other causes (u-joints, ball joints) and think it was the TC all along.
I did not notice any issues with the AT prior.
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.
View 9 RepliesFord 7.3L Power Stroke (1999-2003) :: Small Vibration In Transmission
2001 7.3 auto with 188k miles. Supposed to have had a new tranny at 99k miles. Fluid nice and red with no smell.
Here's problem: during the 3rd shift (gear before overdrive), and between 40 and 50 mph, I get a small vibration in tranny. Seems to be just that shift. It's not noticeable if I run it a little harder on the shift (speed up). If I let it lag on the shift, the vibration is worst. All other gears seem ok.
Questions:
1. I believe I have a 4R100. It has a drain plug, but how do I confirm?
2. I have a couple different scan tools. Should I be getting codes if I have tranny problems? Or is there a scan PID I can check?
3. I was thinking of starting with fluid change. Since it probably hasn't been changed since 99k miles.
Last question: any detailed write on fluid change handy? That would include type of fluid, filter part number, etc?
Ford 7.3L Power Stroke (1999-2003) :: 2000 - Vibration While Towing At Low Speeds
I have a 2000 with a six speed and through the first 2 gears while giving it only a little throttle, worse on hills and worse while towing I have a pretty decent vibration. Once you get to 3rd and up its fine. I have read about axle wrap and due to the fact my springs are pretty wore out I think this is a big part of it. Any other things to look at other than new springs? The u joints all look and feel fine so I haven't touched them.
View 8 RepliesFord 7.3L Power Stroke (1999-2003) :: 2001 F350 - Vibration At Idle
I change my motor in my 01 f350 ccsb to a forged rod one from a 97. When I put the thing in my inexperience cause me to screw up my torque converter in turn ruining my transmission. So after a rebuild I put it back in and she fit like a glove. Ever since I put the engine in i get a vibration at idle.
After I realize I screwed up the torque converter I figured that was the cause of the vibration. But now I know the trans is in properly I still have this vibration I'm thinking it's the position of the motor. I installed new motor mounts when I put the motor in but they were quite a bit off from the original points on the cross member.
My only idea to rectify this was to reinstall the original ones and try to position the motor back where it was prior to the engine swap. Or should I be looking elsewhere?
Ford 7.3L Power Stroke (1999-2003) :: Hydroboost - Vibration In Brake Pedal
So I have my 2000 F250 in the shop because I was feeling a funny vibration in my brake pedal. (isn't warped rotors, I know what that feels like). It also felt like the brakes were on, then would release a little, lengthening my stopping distance.
I took it to a small local shop and the guy said it sounds like the hydroboost. I told them to fix it. Next day, before they start to fix, they call and say they can't guarantee it's the hydroboost and may be the Power Steering pump.
My question is; is there a way to test it to know for sure which part is failing? How do I figure out which one is causing the problem?
Ford 7.3L Power Stroke (1999-2003) :: Bad Clack / Vibration / Smoke At Idle
I have noticed a small vibration at 40-50 mph for a few weeks now and was unsure to the issue.. ( I just checked wheel bearing ect , last night ) . This morning at a stop light she started to white smoke shake and clack, somewhat violently, when I pull away from a stop it seems to smooth out and run normally.. A stuck injector ? Toast injector ?

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) :: Noticeable Vibration Between 20 And 25 Mph Under Heavy Pulling
I've got a 2002 F350 DRW 7.3 truck I'm having a little concern over. It started this summer, when under very heavy pulling I was getting a very noticeable vibration between 20 and 25 mph. I did not think much of it, as it only happened under extreme conditions.
Now I'm getting the vibration all the time, and it's started another band which is 40 to 45 mph. It's much worse if you are very light on the throttle, if you're full throttle it's much harder to notice.
Truck has 154,000 miles.
Ford 7.3L Power Stroke (1999-2003) :: Humming And Vibration When Throttle Depressed
I have a 1999 f-250 super duty 7.3 .... Recently my truck has started making a humming noise when push the throttle and I can feel a slight vibration, the noise and vibration go away when I let off the throttle, I have changed all five u joints, both wheel bearings in the front, the steady bearing, changed tranny and both diff oils, put new brakes and calipers all around and pulled apart the hubs but I can't seem to find what's causing it. What it could be or what I could check? It has an 8 inch lift and is sitting on 37's and some performance upgrades, could any of that cause this ?

I have an 02 F350 7.3 6 speed with only 86,000 miles on it ... Ive owned the truck about a year and a half now and ever since i can remember the transmission has had this growling/Groaning/Vibration sounding noise when ever Im in 1st or 2nd slow rolling with barely any throttle. Itll make the noise going slow and as soon as i let out on the clutch and start moving, but once i give it a little more throttle and start moving at a more proper speed for the gear, the noise fades away ... Id assume its just the transmission making noise due to the low speed and RPM when slow rolling or just starting from a stop.
View 8 RepliesFord 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.
