Tires Rubbing
 

Does anyone hear some rubbing when making tight turns at slow speeds?

I park in a garage with epoxy floors and mostly notice when making the turn out sounds like tires are rubbing the inner well!

No noise when wheels are straight.

Have you pulled a tire yet and looked for rub marks on the inner fender to verify?

Make sure that the dealer removed the spring spacers when they did the PDI If you have to tow it the spacers need to be put back in for clearance on the flat bed. Might be causing your tires to rub.

Yes the spacers are removed. Just got to either look into fender wells or pull them off again and look.

TY....

noisy clutch packs in rear is my guess. Get the fluid changed. How many miles? I changed mine at 1k and it was disgusting. You need the special part # fluid(in owners manual) with GM additive.

no rubbing here, suspect just noise you hear from the flooring, which mine do this on the ZL1 and my Avalanche.

My tires make a lot of noise when backing slowly.

What's probably happening is that the limited slip differential is doing its normal job of trying to keep the two rear tires rolling equally. That will then try to keep the car from turning, and when the front tires are on a relatively slick surface (which I suspect the epoxy surface is), they'll be more likely to be sliding a bit as they roll. As they slip more than just a tiny bit (tight turns), expect some sort of sound to be generated.

When you aren't turning, the LSD isn't trying to slide the front tires at all.

No evidence of inner wells showing rubbing. What would clutch packs have to do with it? Never even heard of clutch pack fluid? The noise is coming from the front tire area anyway and only when slow in a turning radius

The clutches they are talking about are in the rear end....

Limited slip differentials require a specific "friction modifier" additive to keep the clutch packs that perform the "limited slip" function from chattering as they slip to permit the wheel on the inside of the turn to rotate slower than the wheel on the outside of the turn. But that's more of a "chatter". A rubbing sound is more likely to be the front tires sliding.

The slidding part makes sence...ty....will look into changing the fluid you mentioned. 3600 miles!

The best thing to do is to get a proper diagnosis at a dealership. Please let us know the outcome.
