replacing the outer wheel bearings
Has anyone replaced the outer wheel bearings on a 07' F150 4x4? I have a whine coming from the rear end and I am hoping it is just the one of the outer wheel bearings. I have checked the oil,which was full. There were no signs of leakage as well. Any input would be a great help!
Thanks
Matt

Did you do the front? I'm pretty sure you have to pull the axle out and press the bearing off and the new one on. I could be wrong thought. Autozone said kit was $30 for bearing and seal.

Not a difficult project. Other costs you need to consider.
2 quarts of 75-140 syn. gear lube (check the tsb). $50.00
Friction modifier. $18.00
Black RTV. $5.00
Consumables. $5.00
There is another tsb that discribes rear diff. whine. I will try to locate it for you and re post. It would be a good idea to narrow down the source of the whine before you start throwing your time and money at it.
Here is the tsb for the "05 model. I will continue to look for the "07.

Not trying to sound like a dumb a## but what is a tsb? Thanks for the help!

Technical Service Bulletins, or TSBs, are recommended procedures for repairing vehicles. Not to be confused with recalls, a TSB is issued by a vehicle manufacturer when there are several occurrences of an unanticipated problem.
Often shortened to TSB. This is a document distributed by the automaker to its authorized dealers, informing technicians of known problems and how to fix them -- for example, if a vehicle comes into the shop making a specific noise, the TSB tells the technician what is most likely causing the problem.
The first TSB I referred to on the diff. fluid specs, was issued in "05 and refers to viscosity change for the limited slip differential.
The second refers to a repair kit that was developed to eliminate a common differential whine in the "05-"06 - I think.
No problem, I hope we can help, that's what we are all here for.
Also, give us more info. Miles, gear ratios, etc.

When I hear "whine" I think of ring and pinion noise. A bearing causes more or a roaring noise all the time. A R&P will either whine on throttle or off throttle. Also when the bearing fails more times than not the grease seal leaks too which will show up as oil on the backing plate. A little more info will help narrow down the source of noise.

The truck has 66,000 miles on it with a 3:73 gear limited slip also. The whine increases with speed and is not effected by more or less throttle. I drove the truck for 12 miles then felt the axle tubes to see if there was a hot side ,which there wasn't. The center section was warm but not to hot to touch. I rotated the tires to night and found that the boot on the passenger side pvc shaft has a hole in it. But that is the only problem I have found so far,which it doesn't sound like it is coming from there. It doesn't look like it has been leaking for very long. Any help you guys can think of would be a big help.
Thanks!!!!
Matt

You might want to pull your rear rotors and inspect for a bad seal. I found a bad seal, only after pulling the rotors - seems as though the amount of fluid lost through a minor leak, will burn off, leaving no obvious sign of a leak.
I agree with Longbed on the source of the whine. Read the full text TSB I referred to on the "05 model. 05-23-3***REAR AXLE NOISE REPAIR - and see if the symptoms match yours.

If the bearing was just starting to fail then it could sound kind of like a whine, especially if there is some tire noise too. You could pull the axle shafts out and see if the rollers are starting to fail. I have found a few bad bearings by lifting up on the tire and seeing if there is any play, kind of like checking ball joints. Good luck.

[Do the axles have a C clip on them or do they have four bolts at the end of the axle tube like a 9" rear end? I have never pulled the axles out of a C clip rear end before. Is it a pain in the butt? I will jack up the rear and see if I can feel any play in either side.
Thanks Again for the help!

Pull the rear cover and inspect the fluid. If it looks like it has metal in it you may need the ring and pinion. Do you have a "chatter" when you turn a corner? I had my R&P along with the clutch pack replaced @ 35k on mine under factory warranty. It had a whine and chatter in the rear diff.

Troubleshooting. Sounds like you are going to make a repair to see if it fixes a problem.
No offense intended, but your can probably figure this out.
If the sound is coming from an axle bearing, you can probably isolate it by driving the truck on a road with no traffic. If your hearing is not great, bring someone who's hearing is perfect. Get it up to a speed where you can clearly hear the noise, then swerve the truck from side to side while holding your speed steady. If it is an axle bearing the sound will usually go away when the offending side is unloaded by swerving. Sometimes, the bad bearing noise will get worse when it is loaded. If the swerving exercise has no effect, the problem may be elsewhere.
A pinion bearing will usually make less noise when you hold to a steady speed.
If the ring and pinion is at fault the noise will change when the load changes from accelerate to decelerate.
If the carrier bearings are at fault, it is difficult to get the noise to vary with load.
Also be aware that you can get some very misleading noise from tires. If you are really scratching your head over this, get a buddy to swap tires from a quiet running truck, as a test.

Theres no chatter. I did find two bad tires though. The one tire has the inside top outer luggs have two grooves cut into them. There are 15 lugs affected by the grooves. The other tire has two gouges in the side wall. I'm going to get two new tires tomorrow to see if this will clear up the problem. I did check the fluid level,but I didn't pull the cover off yet. I will do that after I try the two new tires. Thanks for the help!

I did find two bad tires. I have tried swering from side to side to see if the sound changes with no change. It does sound like it is coming from the passenger rear side though. Hopefully the tires will fix the problem. If I had a buddy that had the same bolt pattern on his truck that I have that would of been the first thing I would of tried. All my friends are brain washed by the Chevy emblem.
