Hey Guys.
My rear end is making grinding noise at low speed turns in a parking lot.
I just installed an Anti-wheelhop kit and now the noise is much louder.

Any help.
Please.

I remember reading a thread on here talking about the same issue awhile back and it turned out to be a lack of the limited slip additive these things require.

Yeah that^^^ Have you changed the fluid in the rear lately? If you have or the dealer, they probably didn't put the additive back in.

Swap the fluid.

Thanks to those who posted in this thread, I've been having the same noise and will be doing this very soon.

Flush the fluid and make sure to put the additive in there. Don't put the $35 per liter GM stuff in there. Go with something like Amsoil Severe Gear 75W90. They say you don't have to put the additive in with the Amsoil, but I do anyways, it can't hurt.

The fluid was changed in 08 by the dealership.

OMG You guys are the ****.
I change the fluid and not much came out.
I added 2qt of Mobil one 75W-90 and 1 bottle of GM LSD fluid. Rear end noise went away.

Thanks guys.
