I replaced the pinion bearings and races, all is good now, no more noise.
Only the front pinion bearing needed replacing, but I changed both anyway.
The front one was pitted on the rollers, but the race was fine .
The replacement bearing came with the race.
I also replaced the 2 diff. bearings because it was apart allready, and didn't want to do it again.
No More Noise !!!!!!
I could not believe how easy it was to disassymble the rear , and set it back up.
A trans. shop by me wanted $1100 to do the job.
I have less than $150 into the repair for everything !
