Ford Super Duty (1999-2016) :: Whine / Howling Noise - Pinion Bearing Failure
Sep 13, 2013
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.

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.

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?

I have a 2010 6.4L turbo diesel. Without a trailer on a mtn incline I have no issues. She will fly up the hill and she is quiet when I'm not pulling the 10,000 Lb trailer. When pulling the trailer, I have a loud howling noise and reduced performance. I had it at the Dealership and I had them check the engine/turbo and they found no problems? I asked if they tested under load and they said yes?? Someone suggested that the "Waste gate valve" was defective.

2004 F250, I am getting this howling noise when applying the brakes. It sounds like it is from the left front and is more prevalent when applying the brakes down an incline (off ramp, etc) I pulled the wheels off and the pads were probably 50-60% worn. I bought some new pads and installed them and I still get the same noise. I didn't buy the cheap pads, nor the most expensive either. Either way, I can't figure it out. Would I need new rotors? I would think I would have some vibration if the rotors were warped. My other thought was the caliper, but when I replaced the pads it compressed fine and I lubed the slide rails. Not sure what to do at this point. The truck has 94,000 miles on it, FX4, Lariat, Crew Cab, and it has the 5.4L in it.

I have a 2003 explorer where the pinion bearing has started to go, now the rear is starting to whine. the truck is a 2003, its a limited, with the 4.6 v8 in it. I would like to swap the rear with another used one, rather than rebuild the diff. the car is AWD, has a hitch receiver so I would imagine it has the tow package, my question is could I grab a rear out of a non AWD explorer, or one that had the 4.0 in front of it? something with the same gear ratio but out of a similar, non exact car, it has the advancetrac in it with the push button on the center console.

I have a constant whine going down the road with foot on the gas. Back off and it quiets up. At 2-3 MPH i think i can here a " tick- tick". Took the drive shaft off, wheels off ground, cover off and oil out. Spin wheel and i can hear a tick - tick, I think around the pinion bearing. No play up and down or in and out, but it appears to have 2-3 times the backlash i would expect. I used the screw driver- stethoscope--- still think its the bearing. This is a 9.75 axle. What kind of luck would I have pulling the yoke off and going in from the front without removing axles halves and ring gear? I thought I had read that here before. Never done one that way .

Have a rear wheel bearing making some noise. A friend told me that it is always the outer bearing that goes first . Can you replace the bearing without replacing the race?

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 have a 2001 F350 with a 7.3 diesel and automatic trans. I purchased it about 100,000 miles ago. It is all stock as far as I know. The mileage on it was about 14-15 on the road and I decided to put a chip in it. I was somewhat leary of putting too much power to this old of a rig. I put a TS Performance chip in it. It seems to have more power. I am towing a 30 ft. Gulfstream Seahawk I think around 10,000 lbs. When I started up a hill it made a different noise like a screeching noise when I pushed it. When I back off a bit the noise goes away. When I put it back to stock setting the noise is not there just the normal downshift and increased RPM. Not sure how to describe the noise but sounds like a metal bearing type noise. I get the same rush of air or what ever that sound is when it changes back to a higher gear. Is this sound normal or what might it be. It sounds normal when not pressing it.

I have read the older posts here on the super duty ford 4x4 system. At 60,000 miles I noticed what sounds like a gear or bearing noise, or even a whining noise like you would hear from mud grip tires, coming from the front end area, while driving back from Kentucky to Georgia. I have quiet running street tires on this pickup.
I have a 2004 F350 crew cab XL, automatic, 4x4, limited slip axles, 430 gearing and a V10. This truck has always been extremely quiet on the highway. This noise I described above has increased and the truck now has 70,000 miles. I have the factory 4x4 dash switch in my truck cab for the 4x4 engagement. I always thought the dash switch engaged and disengaged the transfer case, and locked or unlocked the automatic hubs.
The service guy at the dealer now tells me that the dash switch only locks and unlocks the front hubs, and the front drive shaft and front differential are engaged full time. So, after checking my tires for defects, and for any play or bearing noise in my wheel bearings, I am looking at pulling the drive shaft out keep the front differential from turning, to determine if I have a bad bearing in the front axle assembly.
Now I read some of the posts here, and they say that with the dash switch in "2 wheel drive", the transfer case should be disengaged and the front drive shaft and front axle should not be turning at all. What is turning up front with the 4x4 disengaged on the dash switch ? I'm afraid to drive my truck out of town now and I need to isolate this issue and get it repaired. This has been a great truck and it's very reliable.

I have a 2001 f250 v-10 4wd with 117,000 miles. I just replaced drivers side front hub bearing assy and not sure if it's the new bearing or what but now I keep hearing this crazy noise from suspension area. It has had bangs and pops for a while now. It almost sounds like abs motor going off but louder. Does it going slow fast or whatever. Brakes on or off. Trucks ball joints were done about two months ago and new shocks, trac bar replaced this summer only thing not done was tie rod ends and all bushings. Brakes are good new rotors and pads this summer also. It's like taking two inflated balloons and rub them together real fast. It may be the timken bearing maybe bad from get go.

2002 F250 4 wheel drive manual hubs, 7.3....
My first thought was to have the tires rebalanced and rotated to see if it is tire noise? I am hearing damage on top of the noise from the 7.3, hard to be sure!

This week was our first nice week of the year. Monday I got in my truck at lunch time turned the a.c. on and it blew ice cold. Today my truck sat in the sun all day and I got in it and turned the a.c. on. I noticed instead of the normal "click" you hear when the clutch engages in the a.c. compressor I got a wine and wimper kind of noise. The system never cooled the air after this happened. Is the compressor shot? Is it safe to drive or is the compressor going to tear itself up and send metal pieces thru the system?

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 bought a 2000 F250 V10 Super Cab. Oddly after a few weeks it has grown on me. There has been a clunking noise out of the right front over bumps. I traced it to a bad axle bearing. The u joint moves up and down about a 1/2 inch. Besides pulling the hub/bearing assembly out and removing the axle are there any surprises getting the old bearing out?

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 have this howling sound in the back that is like heavy tread tires. But thats not what it is. Had to have some work done at a shop (no choice) and they noted on the receipt a "horrible noise".
This is any speed, accelerating and decelerating and coasting in neutral. I checked the fluid in the diff, it is filled to the hole, has good color, smells ok, and no metal on plug. The carrier bearing appears bulged out in one area but the shaft is tight. There is no unusual vibration. The shop did say that I need rotors in the rear.
