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) :: 2002 7.3 ZF6 - Vibration Noise Starting Out?
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.

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) :: Power Loss When Exiting The Freeway
For some stupid reason, my truck decided to lose power today when exiting the freeway. D/s egt gauge verified it with no increase in temp when stepping on go pedal. After about a minute, I could feel it gain power. So, rolled into fuel station, and topped off tank. While filling, I popped the hood and started messing with the uvch and looking around. It was then I noticed that darn hose riding on top of a ton of wires. Pulled said hose up and sure enough, a wire is shafed clean off of insulation. Anyway, something to check while looking around under there....

My rearmost drive shaft u-joint is bad and has slop. I've been having vibration for about 7-8 months, but just started hearing a noise within the past week, especially when taking off with a load on the drive line (uphill or heavy acceleration). The vibration has not gotten worse, just that the noise has just begun to show itself.
I have one u-joint which is OE and has 275K miles on it, and it seems to be OK at the moment. The other two (including the rearmost unit) both have about 100K miles, as does the center support bearing.
Just because I don't want to worry about anything, I'm going to replace all three u-joints with Moog Super Strength units, and will also replace the Center Bearing with a new Spicer unit... just because I can and don't want to be pecked to death with multiple failures in the same drive line. I ordered the Moog joints because the only Spicer joints I could find were for the 4wd configuration.
That's the context... here's my question... The parts are on order and won't get here for several days. I've been driving the truck like it is at about 1500 miles monthly. Do I continue to drive the truck for another week before getting the joints and bearing installed? I know it's a guess... just looking for more perspective.
Ford 7.3L Power Stroke (1999-2003) :: 2000 F350 - Noise Like Exhaust Rattle Or Vibration At Idle
I have a 2000 Ford F350 7.3 with the auto and 262,000 miles on it. As far as I know everything is stock on this truck. It has been a great truck but lately its been making a strange noise. It almost sounds like an exhaust rattle or vibration but it is intermittent. Its not really loud it can be heard best in the cab at idle. I've looked all over on the truck and haven't found anything. I can't pinpoint where it is coming from. I tried starting the truck with the serpentine belt off no change.
I took the inspection plate off the bell housing and couldn't see any cracks the torque converter bolts appear tight, and the starter is not engaged while running. I've read a few forums on the torque converter going bad. It looks to me like its more the 99 trucks that had trouble with that. Did the torque converter issue carry over to the 2000's? Would a torque converter/transmission problem be intermittent?
Ford 7.3L Power Stroke (1999-2003) :: 2000 - Truck Started Bucking When Rolling Down The Freeway
2000 Ford Excursion, 7.3 PS with 210,000 miles. I am on I40 at a truckstop. I was rolling down the freeway last night when the truck started bucking. I pulled of the freeway and here came a thunderstorm. I waited til this morning to check for codes cheap scanner. I pulled a code P1211. I waited for NAPA to open so I could take it in the shorts. I bought a fuel filter and an ICP sensor. After changing them out, the truck runs then starts missing. My battery is about to die so I will finish post shortly.

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) :: Grinding / Vibration In 4x4 Only
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 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.

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 ?
View 11 RepliesFord 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.

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 ?
View 9 RepliesFord 7.3L Power Stroke (1999-2003) :: 2001 - Clunk / Vibration In Rear End
I recently purchased a 2001 excursion 7.3 after driving it for a while I have noticed a significant clunk and vibrate in the rear end. I have read a lot of people saying it could be the slip yoke needing lube which I intend to do but most are saying that their clunk is at start and stop.
Mine is between 30 and 60mph when I let off the accelerator I get a clunk followed by a vibration and when I get on the accelerator it is just the clunk. Does this sound like the slip yoke to yall or am I looking at something more? I have tried turning the drive saft and there is no play in it at all.
Ford 7.3L Power Stroke (1999-2003) :: Vibration In The Front End When Coming To A Stop?
I recently had a flat tire - Schwabs fixed it. Then told me my rear brakes were bad so I replaced them. I noticed when coming to a stop the last 20-30 feet you can really feel the front end vibrate - almost like it is in 4wd but it is not. I checked the hubs and they are on auto and lifted the truck to spin the wheels and made sure everything was dis-engaged. My front rotors were bad so I replaced them and the pads thinking it was the root cause. I also greased the front wheel bearings using the little tool from riffraff diesel where you take out the speed sensor and insert grease.
