Do you have a limited slip (posi) rear differential in your truck ?
it is two wheel drive so I am assuming that it is.
sry, limited slip
If you have a posi rear , this is most likely caused by the clutches in the differential, they will grab and "chatter" on slow speed turns when they are worn. A bearing will cause more of a growling noise and will increase with speed, it will be much louder at higher speeds than lower speeds. You may want to try to add a friction modifier to the fluid to see if this helps first, it might help, if not you will need to replace the clutches, and use the friction modifier when refilling.
I have looked at several sites to find people with similar problem. one suggestion was to replace clutch pack. The other was to try the friction modifier as you suggest.
can the friction modifier be purchased at auto parts stores?
did I mention that it doesn't make that noise when traveling in straight line?
Replacing the clutches is a pretty big job and may be the needed repair, but adding the friction modifier is well worth trying first, it may take a few miles with some figure 8 driving to work the friction modifier into the clutches.
I'll try that. Thanks. I f I have to replace clutches, is that something that the backyard mechanic could do?
Yes, this is do-able, you need to remove the axles to remove the carrier and ring gear assembly, just keep your bearing, shims and bearing caps on their correct side, (right and left) if you mix up the caps or shims you will have problems. Other than that, there is no measuring or setup involved. The clutches need to be stacked just like they come on, one friction plate than one steel plate and so on.
The truck has 106,000 mi. on it, do you think the bearings should be replaced also?
It would probably be a good idea since your that far into it.
ok. Thanks for your help Brian.
