thanks in advance for any and all help.

here is my problem, this weekend coming back from camping rear diff started whining. it is dependent on speed, worse when you go faster. it is does not change based on load. it is just a constant whine/ hum.

I pulled the rear diff cover and besides the normal blackish pieces on the magnet no metal. Truck has 160k on it and has regular maintenance scheduled done to all the fluids.

i went by a transmission shop and they want to rebuild the entire rear to include the gears. the wear pattern on the gears looks good, but i was thinking it was a pinion bearing, (Had one go out in my old jeep).

what are my options and do you really think it may be? I do not think that i trust the transmission repair facility. but all of the ones around here are quoting $1200. I can get a salvage rear end that has 90k one it for $300.


I can turn a wrench I just hate not knowing what is going on before i start. Also I do not have all of the needed tools according to the service manual.

I have done a search and have seen a couple of writeups I am just not finding the answers I need.

Thanks again this is a great site.
