Rear end differential gear loud humming/grinding sound
I bought this van last year and the rear end made some sounds but not as bad as its now.
So, after buying it I decided to open up the rear end and inspect for any damage to suggest it needs repairs. No signs of metal chips, nicks, or any wear on the bearings and gears. After a while of driving it I decided to remove the carriage and pinion from the rear end to give it a close inspection.
After doing this and finding no clear sign of war or damage, i decided to replace the carriage barrings to see if that made a difference.
After placing the new bearings back on the carriage, pinion back into the rear differential, and trying to do it all by myself, i lost the marks i had placed on the carriage bolts and clamps since I had little time to get it back together. After that I had no other choice but to place the clamps bolts where i could estimate they belong. I was done, then drove it and some of the noise went away but a grinding sound on decelerating emerged. Well, now that sound is gotten worst and its more like a grinding sound.
I can assume that not placing back the bolts and carriage clamps back changed the position of the carriage relative to where it was, but am not 100% sure. how can I correct the positioning of the carriage? if that is not the issue what test can i perform to find the culprit?
