Ford Super Duty (1999-2016) :: Rear Pinion Angle - Vibration In The Truck Around 65 - 70 Mph
May 15, 2013
Trying to figure out my rear pinion angle should be. I still have vibration in the truck around 65-70 mph and sometimes around 80mph if i go that fast. I checked my rear axle last night and its at 8.5 degrees on top of the pinion snout is that correct???? And i forgot to measure the rear driveshaft angle but i can do that after work when i get home. Truck is a 2004 ext cab short bed 4x4...

Well, I am getting a vibration In 4x4 99 f250 sd, pinion seals leaking and it has a little bit of movement. I have done a pinion bearing in a crown vic I had before. But not a dana 50. What am I in for, I searched but couldn't find a step by step , how long does it take a back yard guy.

I am working on my Dads 01 super duty with a 5.4, automatic, and the pinion bearing has seized up due to a lack of fluid from a rusted out rear diff cover. The tag on the diff cover had a 10.5 stamped on it and has 12 bolts. Is this known as a ford 10.5"
I have changed gears and pinion bearings in a Dana 70 before is this the same process? What are part numbers for a new pinion bearing and seal? Gears are in fine shape.

I was looking underneath the truck yesterday and saw that the rear end pinion seal was leaking. Looked like it had been for a while. Truck has 35,850 miles on it. Unscrewed the fill plug and a lot of pressure is released. So I'm assuming the breather is clogged somewhere along the line. I have an appointment at the dealer on Friday to see whats wrong. What is supposed to be at the end of the breather tube? Mine has a barbed 45ish degree fitting on the end of it. Its a SRW by the way.

I just picked up an 09 F250 a couple of weeks ago and I was planning on replacing all the fluids since I'm not sure when everything had been done in the past, but it did pull a camper 5th wheel. It has about 93000 Km/57000mi on it
One thing I noticed when reading the manual is that a rear diff fluid change is not necessary on these rear axles unless they have been submerged in water or repaired etc..
Just after I got it I noticed the pinion seal was leaking. It was fixed under warranty but the dealer did not replace the diff fluid as they said Ford will not pay for it.
My question is do you think I need to replace the diff fluid or should it still be good, given the relatively low mileage.

2003 f250 crewcab 6.0 auto 4x4. I all of a sudden started feeling a vibration under the truck near the back when I accelerate and when I let off the gas no other time. No noises or clanking just vibration. I can wiggle the driveshaft inside the carrier bearing do you think that could be it or is it the rear end.

I finally got my lift installed the other day from PMF. My question is how do I get my pinion angle corrected on the front drive shaft? I know Trevor sells a Tcase clocking adapter may have to go that route IDK Unlike the rear there's only so much pitch you can put on the front axle until it causes issues with steering. I was thinking of going with an aftermarket front drive shaft designed to handle harsher angles.
I live in the mountains and after installing the lift and pulling a trailer on some of theses steeper gravel roads I can feel a harshness or something coming from under to front of the truck. I'm unable to post pics since I'm back on the road but I can visually see the front drive shaft angle is definitely not in line like it was.
I'm currently running PMF 2.5 alpha with a 1'' spacer and 3 link kit up front and 5'' progressive leafs and traction bars out back. I was able to fix my rear shaft angle using shims on my carrier bearing ( not really a big fan having 1 1/2'' of stacked shims BTW ) ....

Pinion seal on my truck is leaking. At auto parts store they gave me National seal part number 4278. It does not fit it is too small.I went back and other seal they have is too big. What is the part number?

The other day I pulled a fella out of a ditch. It was a dulley 350 with a lowboy trailer and a small dozer on it.
Well, after finishing and driving away. I inadvertently left the truck in 4x4 while driving on wet pavement at speeds ~30 mph. What I noticed was: when I let off the accelerator there was a low growl/vibration noise coming from the front/under the floorboards while the truck coasted to slower speeds.
I have never had my truck A) in 4x4 on clear roads or B) at speeds above 10mph in 4x4. Maybe they all make noise at low speeds in a quite cab in 4x4. I wouldn't know, I've never driven it under these conditions.
So, can you hear your truck in 4x4 when not giving it gas and coasting on the road?
I did not think I put the truck through too much while pulling that fella out, but now I'm wondering....oh, and I at one point I coasted forward and ran over the towing strap that was attached to my front pull hook and it made a HECK of a noise...could that have done something bad?
4x4 still works, and everything seems/sounds fine otherwise. I might just be hearing the front end putting friction on the transfer case and I can hear it in the tranny as she coasts to a stop (it goes away as soon as I press the accelerator at any speed) but like I said, I've never noticed this before.

My truck had devolped a whine/howl over the past coulple hundred miles. I thought it was a wheel bearing failing me. So yesterday I pulled it into the shop and jacked up the front end. Everthing checked out fine so I jacked up the rear end, started it up, put it in gear and to my surprise the noise was from the rear end.
I pulled the rear end apart and found the front pinion bearing had a defect in the race and the rollers were starting to pit out causing the noise and harshness when turning it. The truck has 130k, seal wasnt leaking and fluid looked/smelled normal. I think it was a legitimate defect not from abuse or lack of maintenance.

we've had a bunch of snow this week and I've been driving around with my hubs locked in. today I noticed when I was slowing down to pull into my driveway I could hear a slight squeaking sound(sounded like a squeaky belt) coming from the front.
I verified it was coming from underneath the truck behind the engine compartment so I unlocked the hubs and went for a drive, the sound was gone. I crawled underneath and turned the front driveshaft by hand and I could hear a slight rubbing sound at the back of the pinion. The bearing doesn't have any play in and there are no leaks. What is going on? Could the bearing be starting to fail or could the rubber seal around the pinion have some grit in it causing the noise?

When I bought my 05 350 dually it had been wrecked, the rear diff was under the bumper and most of the rear suspension, including the back part of the rear drive shaft was in the bed of the truck. I have gotten everything back in place, and have driven the truck for a few weeks, but I knew I was going to have to replace the ujoints because there was visible damage to one of the caps. I have also had a vibration at about 45 mph. I had no way of knowing how the original driveshaft was oriented at the slip yoke so I went with best guess. Now in my research I read that if the driveshaft is not put back exactly in the same position vis a vis the slip yoke it will be out of balance.
Also if the drive shaft is dropped it is scrap, and if I have any lift on the truck {it had 4 inches when I got it} the whole thing will shake itself to pieces. Most of the answers to other drive shaft questions talk about taking things to a good driveshaft shop. No such thing here in the vast stretches of My state. I am pretty much on my own as far as building or repairing this thing. Is there any way to determine how the shaft was originally oriented? I also have some damage on the end of the yoke and will have some trouble getting the ujoint apart. Is the shaft now junk? And if I get an ebay replacement, how do I tell if that shaft is in the right orientation?

So I'm getting a mild to severe shudder depending on load and acceleration rate from stop to 10-15mph... It's worse if I'm on an incline...This has started since having a lift installed...I'm guessing it has everything to do with pinion angle...right?

2003 in sig. when going around corners slow I can feel and hear a chatter or vibration coming from what I think is the rear end. I am running amsoil 75/140 in it and added some friction modifier. Do my clutches are shot and making noise or do I need to add more friction modifier ?

My 2003 Ford F250 V10 seems to have a vibration, sometimes at all speeds and sometimes at freeway speeds. I replaced front hub assemblies and ball joints and rear calipers last year. When braking i have a vibration in rear as well, which I think is from uneven rotor but can it be causing my vibration? Also sometimes I can smell hot brakes from the rear.

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....

Ok so I think I have sticking calipers on the rear passenger side of my truck, not 100% sure but ill be getting under the truck tomorrow to check. My question is how hard is it to fix this and how long do you think it will take? I have all the right stuff to get the truck jacked up and I have enough money to do this, time is just the issue. It gets dark around 4:30-5:00pm here and I get home from school at 3pm, and have work also but not until saturday this week.
I'd prefer to do this after school if possible because I've stopped driving it so that way I don't wear down my brake rotors and pads for no good reason. I have to drive the work truck that has many of its own issues but its driveable, headlights are very dim due to oxidization and is dangerous to drive in the snow due to the tires (no money to replace right now). How hard and how long this would be? What else it could be shoot! The problem is, it slows down if i let off the gas as if i was breaking, high heat from rear passenger side brakes/burning rubber smell.

So When driving around I'm hearing this squealing almost chirping noise and it sounds like its coming from the rear of the Truck. I greased the bushings and leafs but that didn't fix it, to me it sounds like a rotating noise. Don't think it's the brakes cause it makes the noise when driving not stop.
Also, a bad alternator would make noise while driving over 40+mph, like a loud whistle?

I know this has been discussed but I still don't understand. Hence my "dumb blonde" user name.
I just purchased a 2013 super duty f350 extended crew cab DRW.
I also purchased a 42 foot (box is 36) Goose neck Bison LQ horse trailer. Trailer weight is 12048 and tongue weight is 4468. Fully loaded I am about 18,500.
Truck pulls and stops great but it is obvious the rear suspension is sagging.
Now what? Do I need air bags? Timbren? Spring Coils? I have called several installers and they all say something different.

I bought this Ex a little over a month ago and finally got around to replacing some stuff.
I have a slight vibration between 50 and 60 MPH. The vibration is the same weather I am accelerating, in Neutral, Coasting down (well, a little bit worse when coasting down), in 2WD, in 4WD, turning, going straight, hot or cold.
I have replaced the following:
Rear Driveshaft U-Joints
Tires and Rims
Upper and Lower Ball Joints
Wheel Bearings
Steering Stabilizer
Cleaned and Greased the Hubs
Greased everything greasable up front
I still have the exact same vibration as when I started. I can feel the vibration in the steering wheel as well as in the body of the vehicle. I am thinking that it may be in the steering linkage. If there is a loose joint then the wheels would be allowed to jiggle a little bit. I am at a loss. What else should I check?
Also, When doing the ball joints, I noticed that the tie rod ends were quite stiff. How stiff should these be? I can't move them by hand, but they will move a little bit when moving the free end of the tie rod.
I am taking it in for an alignment on Friday, and if I can't figure this vibration out, I might have them take a quick look into it. Would a stuck slide pin in the front brakes do this? Both sides on my truck are seized at the current moment.

I have an 2011 F250 gas. I get what feel like a wheel vibration at 48 to 50 mph. It then go as you go up in speed. Comes back as you go down in speed at about the same range. Had it at the dealer for a month they but new tires and one new wheel on the truck. Same problem. Moved up to Ford. The sent me to another dealer. Ford now tells me that this is a problem that exist in the truck and there is nothing they can do.
