Ford 7.3L Power Stroke (1999-2003) :: F250 - Slight Vibration / Medium Roar Seemingly Coming From Front
Sep 2, 2017
Early 99 F250 7.3 Manual 4WD Extended Cab Short Bed
I am at a loss. I have a slight vibration/medium roar seemingly coming from front. I have tried fixing/replacing several things, with no luck. When I get above 35-40 mph, I can hear a whirling vibration that sounds like tire tread noise (very little tread on tires). When I tap the brakes, seems to make a difference, seems to get louder as I slow down. I can feel it in the clutch and accel. pedals. It is consistent, when I push clutch in and let idle at 45mph, it is still there. Doesn't seem to make a difference when swaying back and forth, maybe a little. When i get below 25-30mph it isn't noticeable.
Here is what i've done so far :
1.Replaced both front wheel bearing assemblies, rotors and brakes
2.Replaced drivers side brake caliper (seemed to be sticking a bit?), will do passenger side tomorrow
3.Serviced both hub locks and verified front axle is not engaged (one was locked for some time, I thought I found issue, but still have vibration)
4. Tightened pitman arm joint, was slightly loose (need to replace)
5. Inspected tie rod ends and other joints, see no noticeable movement, but have not marked them off the culprit list.
6. Tightened output shaft nut, was a little loose
7. Raised rear end off on jack stands, and revved up to 50 mph, and no vibration, so I have excluded u joint and cardan joint, everything points to front end
8. Rotated tires, left front to right rear
What I haven't done :
1. Have a leak in pinion seal, not replaced yet
2. Seems the upper and lower ball joint had the slightest, I mean slightest play in it when lifting the front driver side wheel (I mean less than 16th inch) but could hear it. I haven't done anything with this yet ... may be the problem? Would a tire out of balance wreak this much havoc with this amount of movement?
3. Haven't replaced the pitman arm joint, will but not sure if this can create issue.
Nothing I've done seems to make a difference.

I'm looking at a 2004 F250 XLT super cab 4x4 with a 5.4L with only 50k on the clock. It looks to be in great shape and drives good with only a few issues. Cruise doesn't work, it pulls to the left a little, and it has a slight roar coming from the left front wheel. Other than that it seems to be a nice truck. Its blue and grey two tone. Anything else I need to look at before pulling the handle on this one?

Ok, still working out some issues: It may be normal, but I hear (not feel) a slight roar when I'm pressing throttle petal very lightly. Seems to do it as we'll when I'm backing off throttle but it stops when I let off pedal completely. Not there when I get into the pedal. Not the tires because it stops all together when I get off throttle and let it roll. Turbo maybe ? Rear end (wouldn't it do it even when rolling)? No vibrations at all....just a little roar.

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.

Tonight on my way home I noticed a slight creaking sound, coming from front driver side, opening the window it was more noticeable. So when I got home I have tried to locate the source, it is the same with or without the engine running & you can hear it by rocking the steering just a little left to right. It sounds like a dry bush, I had my good lady rocking the wheel while I climbed underneath but couldn't pinpoint it, so I climbed up on the fender with my weight on the radiator support & the battery cover, when she turned the wheel the sound was almost gone but as soon as I jumped off it was back! I then tried rocking the truck from the driver side fender & the sound is there but not quite so pronounced, Any other way before I spray everything with WD40 (don't know if you have that over there but it usually quietens things like this!) There is no play on anything anywhere & the truck has only around 32k miles.

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.

A little about my truck. E99 F-350 crew cab long bed dually 4x4 223K miles. 4.10 gears with LS in rear.
I bought the truck June 2016. I ended up wrecking the truck on the test drive. Thought it was a 4 way stop and pulled out in front of a lady and she ran into the passenger side tire. Only damage that was on the truck was a busted tire, and the fender smashed in. Some how missed the door and the bumper.
I replaced all the front end: u-joints, ball joints, steering linkage, brakes, rotors, calipers, and all the u-joints in both of the drive shafts, also changed the fluid in both axles.
I have started to notice a slight "vibration" "shimmy" while driving down the road. Mainly while in a curve or changing lanes; applying pressure to the steering wheel one or the other. Tires have been balanced, and rotated several different times now with no luck at all.
While backing up, I can feel something "popping" "clunking" especially while turning. Like backing out of a parking space.
Insert troubleshooting:
Jack truck up and put on jack stands.
- Pull and shake all tires. --No movement
- Put in drive and watch all the rear end. --Nothing shaking or out of sync.
- Put truck in 4wd, hard to engage, watch front end. --Nothing shaking or out of sync.
- Turn tires to full lock. --Drive line starts clanking and shaking and rear tires acting funny.
- Turn tires straight. --Problem goes away.
- Put truck back in 2wd. --No problems when turning wheel lock to lock.
- Drive to empty parking lot. --Mainly feel problem while backing up, really have to feel for it. Most people call me insane.
- Lock the front axle. --No difference.
- Put in 4wd. Drive straight --No difference.
- In 4wd while turning. --Truck wants to act like it is fully locked in the rear and will bind up and slip a tire. You really have to give it some fuel to make it even try to move, and its almost like the truck wants to fold in half on itself. Cant keep the steering wheel in one spot as it keeps "jumping" on me.
- Put in 2wd. --Acts the same way until the truck fully comes out of 4wd then smooths back out to where you have to really feel for it. 4wd light stays on forever, before going off later in life.
- Put in 4low. --Gears grind and will not engage.
Would this indicate that the transfer case is messing up on me? Why would the rear axle feel like it is locked when in 4wd?

I'm looking at a 2001 Excursion with 242k miles. Truck is all stock, and everything checks out well. The only thing is there is a slight vibration at idle, that increases quite a bit when the engine is revved to about 12-1500rpm. Ran a CCT, and #8 was flagged. I know that can be somewhat normal depending on the CPS, right? Otherwise the truck is smooth, and in great shape. Should I be concerned about what feels like a slight miss on #8?

I have a 02' 250 4x4 with 250000 miles on it. While driving between 55 to 65 mph there is a roar and vibration that seems to be coming from the rear. I have about 35% tire tread left and have had the rear tires balanced and it still does it. Having issues with drive shafts unbalanced or rear ends?? I am not sure where to start....

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.

2002 Ford F250 4x4 Superduty Lariat (4 door). Just changed the locking hubs to a new set of Warn manuals. I began to periodically hear what sounds like a rumbling/bearingish/howling kinda sound. Happens when you hit a bump at any speed...then howls till you hit another bump..goes away..then process repeats. Come to a complete stop, and the sound usually goes away till you hit another bump. The hubs are "free" at this time.
Heres the weird thing...when the noise starts...I switch it into 4 wheel drive on the dash...the sound instantly goes away. Click it back outta 4 wheel drive (hubs are still unlocked this whole time) and the sound is gone. drive some more down the road, maybe hit a slight bump, and the sound returns. Switch it back into 4x4...sound instantly goes away. Its not really in 4 wheel drive, cause the hubs aren't locked in...but that cures it till I take it back out. What could be causing this howling ? Its getting worse, and you can feel a slight vibration in the floor now when its doing it.

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?

Shortly after i bought the truck and started driving it home, it shut down on me while coming up a mountain on the interstate. I had probably drove it about 10-15 miles and about 20-30 minutes of running after being dead cold. The temp gauge was about in the middle and it would not start up again until about an hour and a half later, which I was able to drive it home another 20 miles away.
There are no codes, which a mechanic told me it is probably an intermittent problem then. He then told me it would either be the cps, ipr or fuel pump. I have changed the cps and since then have not been able to replicate the problem but I have also not been able to get the engine up to temp because of the recent weather being so cold. I want to test the truck and see if I can get it to stall again but what this could be or what I can do to test the truck?
The truck is a 2003 f250 7.3 4x4 automatic, short bed, crew cab, with 320k miles.

2001, F250, 4x4, 432,000 miles...
Seems this truck eats up bearing assemblies. Its like every 2-3 years, I'm having to replace one side or the other. And we talking like 30-40,000 miles....
BTW.... although I'm not out doing much 4x4 driving, this truck does do a lot of dirt roads, probably over 50%...

I have a 1999 f250 7.3 I was driving down the road today and I lost throttle along with my check engine light coming on. I pulled over and turned my truck off and now it will not fire back up.

I just came back from a 200 mile trip and parked my truck. Next day, got in the truck and turned the key.... it turned over and white smoke coming out the tail pipe. After doing some research(you tube),I ruled out cps sensor because it was showing low rpms on tach. Replaced glow plug relay and still have same issue.. what else to look at that I can do without getting it towed. Hunting season coming soon and I need the beast.

I have some whine coming from my front wheel bearings so I'm going to replace them both. I'm not sure if this had been done on my truck before, but I'm thinking so since I have Moog greaseable ball joints.
Truck has 250k miles on it. I'm going to check the pads, rotors and slide pins. Anything else that might need work? I'm sure the half shaft could use a once over, but I don't keep my hubs locked so they don't turn much in regular driving.

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?

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?

I have a 2002 f250 7.3 and the belt is rubbing front edge of the belt and making a whipping sound at 65 mph. Have replaced tensioner, idler, water pump and a/c bearing & pulley.
