rear end howl

I have a 91 Camaro 305 automatic and the rear end is howling. Is there any type of additive that would quiet this up? Thank you.

A howling noise indicates worn or damaged bearings or gears.

Aside from axle bearing replacement, differential service isn't really a DIY project unless you're very well equipped and know what you're doing.

No additive I've ever seen will replace missing metal. There *may* be an additive that'll quiet the noise, but it will be a short term fix at best.

The cheapest fix for this problem would probably be a used rear end assembly.

Did it just start howling? If it has always done it, it might be filled with the wrong oil. On some R&Pís and differentials the wrong weight or type of lube causes howling because of inadequate lubrication, or cavitation of fluid.

Agree with Knuckles.

Weld: The wrong fluid causes chattering not howling (such as not adding the GM additive in a posi)

Yes, I forget that things are different with the bigger trucks I work on.
