Was Not the Wheel Bearings, Rear Diff?

[NiveK1970]

Changed out both rear wheel bearings, no change, still roaring like 747, goes away under acceleration, how hard is it to rebuild the rear diff?

Are you positive it is coming from the rear end? If so... I would check the diff fluid level to make sure it has gear oil in it..

 

[NiveK1970]

ya i need to jack it back up and take the filler nut off and check, i looked around it there are no signs of it ever having any leaks, and I am almost totally positive it is coming from the rear

When you replaced the wheel bearings, did you replace both inner and outer? Was either dry or were they all good? Brakes look good? Have you check the Ujoints for grease?

 

[NiveK1970]

damn the ujoints take grease? , been a long time since ive seen a zerke ******, guess i better get my ass under there and give it a thorough going over

 

[joey]

they do up to a certain year... on disco's = early 99... not sure on the RR's.

What year is your Classic, how many miles on it and when was the gear oil last changed?
I would inspect/grease the u-joints, replace the gear oil, checking for water and or metal in the oil, and then see what happens. If still there, get back to us.
