Help rearend noise - The 1947 - Present Chevrolet & GMC Truck Message Board Network

LS1 K-5 Blazer · 11-09-2002, 03:55 PM

12 Bolt 71 K-5 four speed.
I posted this in the none specific section but it is really kicking my A**. I looked at the brakes they are fine, change the rearend fluid, everthing looked good for being 31 years old. With rear tires in the air if I spin one of them I get a clicking as the teeth mesh, What is "Normal" noise for one of these.
The noise that concerns me is the one the shows up on deccleration. It is alsmost like a Harmonic, I even get a vibration. It also gets loud when coming to a stop brakes applied or not.
Any help would be great
Thanks!
