Ford F-150 - 1997-2003 :: Constant Whine - Rear Axle Pinion Bearing Replacement
May 19, 2012
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 .

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.

Looking for a video, pictures, or steps that are in depth on how to replace my rear seals and bearings? They are leaking very badly and would like to see some other ways to get it done.

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.

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.

It's time to replace my axle bearing and hub assembly. Looking at RiffRaff site they show 3 different models. Early 99, fine course and course. I think I have the course thread but just want to make sure before I order. My truck is a L99 and I don't have the abs sensor. Looks like all 3 have come with the abs sensor. Do I simply not connect the sensor? Here's a pic of what i have. Course thread?

We've had a lot of rain here in pa lately and i hit a few big puddles the other day and now i have a growl slash wine in the front of my motor,now i narrowed it down to something driven by the bely because I removed the belt and no noise all pulleys feel good and smooth except the ac compressor if you spin it by hand it has a rough/dry feeling and sound to it but the noise doesn't change with the ac on or off its just constant grinding/whine. Replace the ac compressor pulley bearing that what I am thinking it is and don't really want to change out the whole compressor..

When I am coasting in reverse or forward at low speed e.g. 5 mph, I am hearing a whine that seems to be coming from the rear axle.
Usually it happens just after I have shifted OUT of gear (it's a manual transmission).
I uploaded the sound as a WAV file to here: Note! I recommend that you disable flash before going to this [URL]......
When I speed up the whine just rises in pitch and it's making my ears ring. What that sound might be? Maybe I just need some "axle grease" or something?

i'm just wondering if i need to worry about preload and backlash if i just pull the carrier out and replace only the carrier bearings. would simply replacing the shims in there original side keep the specs where they should be with new bearings or would i have to completely dismantle the housing and start from scratch.
I only ask because you can move the entire carrier by hand and see the slack in the bearings but i don't seem to have any noises or vibrations coming from the rear end so i don't know if it's worth tearing into...

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 a 97 F-150 with just over 300,000 miles. I lost all oil pressure and know I need to replace the main bearings. Must I pull the engine to do so?

I changed my rear axle grease a couple of weeks ago and now I see some fluid coming out of the pinion seal. Do you think I overfilled it or do I need a new seal?
How hard is it to replace the pinion seal, will I need a new crush washer and will it knock out the preload?

1998 F-250LD 4X4 ... The outer boot is cracked, so I got a new one. Took the axle off, but cannot understand how to remove the boot. Where do I take the joint apart?

I have a 73 F100 with a 9" rear end. I need to replace the drivers side axle shaft as the bearing retainer is starting to slide off and I'm not willing to take a chance a new bearing and retainer will do it again. They are 31 spline axles and have the ball bearings not the tapered rollers.
What year trucks can I find a replacement axle shaft? Any other thing I should be aware of in finding a replacement?

I own a 1999 F250 super duty and have the front end apart to service the u joints , I noticed that i have bad axle stub needle bearings on one side. I was wondering what is involved in taking those out and replacing them, it looks like they are held in place with some type of spanner nut. My next question :Would it be worth the cost just to replace the whole bearing hub assembly? The truck has 134000 miles on it.

I had the rear axle seals replaced less than 1000 miles ago. Now the axle is getting whiny. First I thought maybe that the tires made noise but now I'm pretty convinced it comes from the axle.
With a seal replacement, what do they do that might impact the axle - over tighten the bearings?
I also had the rear diff fluid replaced - perhaps they put in the wrong stuff...
Should I replace fluid and see if that stops or should I simply take it to the dealer and let them deal with it?

had a leaking rear driveshaft seal at the axle and replaced it and fluid. 75W145 full synthetic as recommended. it was changed at 128000 and I've started to get an axle whine over 25 MPH up to 65-70MPH. quites down around 80 MPH. I just checked it after 2 months (whine just started) with 133000. Any TSB. does this fall under TSB 05-23-3? Noise sounds like I've got really aggressive tires on the truck. Only have Dayton HT all season. Did not add the XL3 additive. Would this work at this juncture.

I have a 1998 F-250 LD 4x4 with 462,000 km. I have been hearing for some time quite a drone coming from the rear axle. I am guessing the wheel bearings are due, as both front ones have been replaced, but never the rear. More about the noise, I hear it come to life as I gain speed. The faster, the louder. If I decelerate the noise is still present, but volume significantly decreases. Should I change the oil and friction modifier and see if there's an improvement or go ahead and change both bearings too?

How does it come off. I wasn't able to turn the axle vent without turning the block on axle for the brake lines.
I would like to remove the brake system from my current axle without breaking any lines open, then putting a new axle in and put the brake system on the truck to the new rear axle.

I've got a 2003 F150 4x4 supercrew that's got a 9.75" rear end with 3.73 gears. I just replaced clutch packs and spider gear set 2 weeks ago. The last day or two I have noticed that when I make sharp turns that it get a whining like spinning noise. It sounds to me like the spider gears are spinning. It only does it when making sharp turns. There is no noise going down the highway or normal driver. I have noticed at times I get a little shutter when I go to take off or back up. Kinda feels like a brake is hanging. I put friction modifier in when I did the clutch packs and everything. Maybe not enough?

I got a 2002 f150, right now it has a 9.75 with disc brakes. But it exploded. I can only find a 9.75 with drums in the wrecking yard. Can I just swap my disc brakes on to the axle with drums?
