Another thread on rear diff. lubricant.....
I didn't want to hack the other thread going on with rear diff. questions, but it influenced me to post my issue with my rear diff.
I have a 2003 Chevrolet Tahoe, 5.3 4x4 133,000 miles. About two years ago, I had some work done at local shop on my Tahoe as my emergency brake was really screwed up, and they ended up having to drain the rear diff. fluid. A holding plate was screwed up on my e-brake, which was connected with the rear axle. 6 months or so passes, no issues.
THEN, the rear end banging, clunking, chattering, bumping began, especially during deceleration. I tried talking to the local shop who fixed the e-brake, and them damn fools could hardly tell me what type of fluid was even used.
So after talking with the local Chevy Dealer, they said try adding a anti-slip. That's what I did, and it still makes the same damn clunking, chattering etc. and its been another year.
SO, what should I even do?? All my manual states is use 75w90 synthetic axle lubricant. Should I trying changing it again, and make sure I put in the 75w 90 synthetic, because honestly, who even knows what the repair shop ever used!!
