Ford Super Duty (1999-2016) :: Squeaking Noise Coming From Front Differential Pinion
Jan 2, 2016
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?

For starters I have a 1999 F-250 5.4l changed all 4 ball joints about 15,000 miles ago. I have been hearing a grinding noise coming from the front end for the last month only when I turn left and at slow speeds. I was servicing the TC so I threw it in 4 wheel to check it and it wouldn't engage until I started moving. When it did engage it was a bad grinding/ clunking sound coming from maybe the differential.

So to start at the beginning.... Traveled across Canada East to West towing 11000lb travel trailer, no problem. Have used 4x4 in a few campsites to pull out of a pitch without spinning the wheels and causing damage to the site when it has been really wet. All good.
Got to Banff in December and the town was an Ice rink, engaged 4x4 and all good. Crossed the Rockies and the 4x4 starts making grinding noises. Up and down some mountains and squeaking, grinding noise then clunking.
I have manual hubs, disengage and the noise all goes away. Engage 1 hub and no noise. Engage both hubs, noise back.
I bought some needle bearings and went to swap them. Got hubs apart and they look good. No scoring on the drive shafts. They are not dry, but as I have them open, repack them with grease anyway.
Do more research... Remove ABS sensor and repack main bearings with grease. (broke one sensor pulling it out, too cold plastic brittle oops). Still clunking noises.
The universal joints look good, doesn't appear to be any play in them. However, the axle seal (knuckle seal) (F81Z-3254-CB) does move around a lot in it's metal casing. It is tight on the shaft, but with the hub off, I can move it in and out, and move it side to side. If I had ESOF hubs I guess they would not be locking as I'm sure there would be no vacuum in there!
Question is then, would this seal be allowing the universal joint to wobble under load in 4x4 mode? Would this wobble be the cause of the rumble? As it is labelled as a seal and not a bearing, I wouldn't of thought this would have been a loaded point, and the weight would have been taken by the associated bearings and it could be run without this seal? But if it is not this, then I'm still looking for a clue as to what is making the rumble....

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.

Wondering what difference in tire pressure are you running front to rear. I have a 1999 CC LB 4x4 with a v10 with 180k on it and have always had to run lower on the rear with a empty bed. Most of the time I'm empty. If I don't the rear centers wear a lot quicker.
I ran KO's most of those miles and recently switch to Geolanders. The tires are 315x75x16. BTW the geolanders are doing great. A better rain tire, smoother and much more quiet. 6k on them so far and very little wear. Time will tell, I would get 55-60k out of the KO's.

My 2013 f-250 with 6500mi. has peeling paint on the front differential and the axle.. I sprayed it with some fluid film for now.

With the front hubs locked locked I get a ticking noise out of the front axle almost like there is rocks in the hubcaps. But unlock the hubs and the noise goes away. Also, if I put it in 4 wheel with the hubs unlocked i get no noise.

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 you say no 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?

I have a 2002 F-250 7.3. I was driving home from work on Tuesday (highway), I heard an intermittent noise coming from the front end, sounded like a rubbing/grinding noise. Yesterday on my way to wok, same thing, on and off. Yesterday on my way home the noise was constant, didn't go away. The noise comes at about 45mph and stays until I'm back under about 45mph, so mainly just on the highway. I put the truck in neutral and let off the pedal and the noise is still there which tells me it isn't engine related.
Yesterday after work I jacked up the front end, spun the tires, no noise. No play in the tires top/bottom or side/side. Took the tires off and what I did notice is the right axle u-joint is shot. I am hearing the noise in 2wd so I don't know if its the u-joint that's making the noise. Could it be a bad wheel hub bearing? Is it the u-joint? Maybe needle bearing??

2012 truck, started making a noise today. I cannot tell what it is, but seems to be coming from the passenger front suspension, its a crunching/light clunking sound, happens when going over bumps, when the truck pitches one way or the other turning, and coming to a stop....
Truck has 6k miles, I did a quick visual inspection this afternoon, didn't notice much, but the sway bar endlink looked a bit odd though, not sure if normal, its gota little bend too it and seems to just contact the vac line mounted behind it, seemed unusual...
Maybe its its just one of the crappy rancho branded shocks is junk?

I thought there was a v10 specific superduty section like how the psd does, but my thread went in the "performance, engine, troubleshooting" section.
I wanted more exposure than that particular small viewed area.
I don't have a video of the noise, but my 99 f450 v10 5spd has some iffy noise coming from the front. I've read so many threads on this and they either end with "my motor had 1-2-3 bad pistons" or "my flexplate was cracked" and all that dealt with chain tensioners were never finished.
I know what piston slap sounds like (worked on many cobras and lightnings with forged pistons that had it) and have experience with bad wrist pins and broken piston skirts, and this noise doesn't sound like any of it.
Noise is a loud clicking/clunking/Detroit diesel idle noise. When you rev the engine up it doesn't lighten or get better, only worse as rpm goes up. Oil is terrible looking, I'll be getting that changed this week.
Story on truck. I've had this thing for 4 years with blown motor. I got a buddy that acquired a parts truck and he said it ran good. I dropped my truck off and he swapped the engine. I got my truck back running, but with this engine noise. He said it needs to get run some more and change oil.
I think it's timing tensioners, my buddy says it will come out of it, a mechanic friend says it's going to blow up "because they all do" and I don't really want to replace the engine again.
If it's tensioners, how big of a job is it. I have the cam clamps and crank stop and the ford tools to make sure crank and cams don't rotate while apart.
I'm just 650 miles from my truck and may need someone else to do the work. Which sucks.

So today I was backing up my 11000# fifth wheel at the campground when at 1500-2000 rpm I hear this awful shrieking sound coming from under the hood. I heard it the whole time while backing up and under a load. I never heard it once going forward. So when I get home I put it in reverse and hold the brakes and again I hear this shrieking sound coming from under the hood I get it up to 1500 rpms or so not moving just holding it and the more throttle i apply the louder the shrieking gets.
Now remember the truck is not moving its just spooled up, holding the brakes. I think that maybe something is wrong with the turbo, but I dont want to jump to conclusions. This truck is a 2001 F350 SRW CC LB 7.3 161,000 2 owner miles, 4 inch turbo back FLO PRO Straight pipe, and gauges everything else stock. What is moving that is making this horrible sound.

My 99 F250 has just recently started making a "rattling" noise. The noise sounds like its coming from the front left wheel area. The noise is constant while driving down the road, its NOT created by bumps or anything, its a constant noise while moving.

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.

2002 F-250 7.3 4x4 ...
I have a rattling noise coming from the front suspension (both sides) when going over small bumps. Most people point to ball joints, but I find my case odd because I just replaced
Upper/Lower ball joints
Track bar
Tie rod ends
Shocks
Front U joints
Drag link
I did not touch the leaf springs or the sway bar, except to grease the links, which otherwise looked good.

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...

I have an '08 F250 w/ a 6.4. A couple days ago I started getting a loud squeaking when I turn to the right. It only does it under speed, almost like it needs the weight transfer to make the sound. In addition it's only when I turn at a like 45 deg angle, I can turn less or more to make it stop. But it has gotten louder and louder.

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.
