popping noise in rear end of ss camaro 2000

put new grease in rear end and limited slip additive have no clue what the hell the noise is it has a wobble when you accelerate.

Did you check your ujoints? Its either that or your rear is living on limited time....

What grease?
Should have been gear oil. Some good heavy stuff.

i put the factory 70w-140 and limited slip additive but like you said the rear end could probably have gone south. but is there anyway there could be slack in the axle due to the fact that it only does it when i turn? because it doesn't make a roaring sound it just feels loose and its like let me say it make a sound like a shock does when the bolts are loose but the shocks are not loose i was just using that to explain the sound. I feel stupid as hell cause i've been around cars all my life. I just restored a 68 ss from the ground up and this just baffles me, maybe i just don't like the sound of buying a new rear end.

so wait a second, this problem AFTER you only changed the diff fluid?

Are you sure you accounted for all tools and parts afterward?

could be the center pin coming loose. those bolts like to break and if it broke at the wrong spot that thing can sling out and catch/catch/catch until it eventually wedges :o. might pop the thing back open and have a look. 70w-140? SAE 75W-90 Synthetic Lubricate GM P/N 12378261 or Equivalent Limited Slip Lubricate Additive GM P/N 1052358 or Equivalent. thats what the factory recommends.

LOL!!!!

Hope you get it fixed

I left a wrench on the parking brake adjustment nut and started driving and heard it rubbing on the driveshaft. Scared the crap out of me. Someone called me and I forgot all about. So i would definetly say go take a good look.

Didn't say it to be a wise ass or nothing, we've all done it at some point.

My 2000 Z28 has a Torsen posi not the old Auburn style, yours should be the same. Posi additive is not needed with the Torsen.
I used 1.5 bottles of Mobil1 75w-90 gear oil.

Yea guys i think the guy is right about the pin, i've asked a few other people and they've all said the same thing, so guess what that means i'm gonna be doin tonight. I appreciate it guys yal have been helpful. Oh and no tools left behind, I tend to lay my wrenches on the ground.
