ok...weird sound coming from under the back of the car when im turning at slow speeds

[BNK]

ok so whenever im driving at slow speeds (like at the mall) and im turning i hear something that sounds like the back tires are rubbing in the wheel wells but theres no way that they can be rubbing because i have the stock tire and rim setup. i dont know what it could be. Does anyone have any idea what it could be?

i drive a 1995 M3 if that helps

thanks

Might be the clutches in differential.

At 37k, mine had a weird sound/feel at low speed/hard turns (parking lots).

Draining and a fill of Red Line and additive it's happy.:awink:

change your diff fluid.

There are a variety of LSD additives that are designed to fix excessive slipping/grinding in the diff.

Although many that you may find at the auto parts store may be perfectly fine, I would suggest stopping at a Chevrolet dealer. There is a GM-approved LSD additive designed for Corvettes that works very well. This web site allows you to order it online:

Here are examples of aftermarket brands:

Hope that helps!

can you point us in the right direction about how to change the fluid? ( mine has that sound and probably needs it as well)

From the E36 M3 FAQ:

Be forewarned you will probably need to buy a short profile allen socket to get the fill and drain plugs in and out.

i used redline 75w90 and my noise is *much* reduced, though I am intrigued by what Rob has to say about using the corvette diff fluid. Rob, by the way, I finally got your stage II flywheel in with the 6-speed Getrag... i'll have to tell you about it.

cheers,
