So I drove my Mustang to school for the first time day, and as I was driving through the parking garage, going really slowly and pulling tight corners, I noticed my rear passenger tire kept squealing a bit when I gave it a little gas. I also had this problem at home on the gravel getting my car up onto ramps: the tire would start spinning out pretty badly. It's just the rear passenger tire. My grandpa said it might be the differential, but I have no idea how that works, and it seems like it might be a somewhat involved fix. Is it the differential? And what can be done about it? Thanks in advance!

Does it matter what direction you are turning? Do you know what type of differential you have?

I've had the tire sqeeling in parking garages before. I believe it is because the floor of a concrete garage is very smooth and this is easy to do. You may also be giving it a bit too much gas for the slippery concrete surface.

I think you have an open (non-positraction) rear differential which under conditions you mentioned in gravel, can cause only one wheel to spin. You need to ease up on the gas a bit. I think you are used to whipping around in modern cars and these old Mustangs just don't act like the newer cars.

It doesn't seem to me that there is anything wrong with the car that changing your driving habits a bit, won't cure.

As far as the ramps go, I'd get some plywood to put under the tires, when pulling onto ramps. Ramps just don't like gravel - it's too loose for good traction.

I know nothing about differentials. As far as I know it's the stock one.

Well I thought I was taking it pretty easy, but I'll go slow and see if that's all it is. Thanks guys, hopefully it's not actually a problem

there is a 99.99% chance that you have an open differential which means that you only have one drive wheel (passenger rear) which isn't great for traction, and is subsequently great for spectacular burnouts . but just about any light weight car will squeal a bit on smooth surfaces when turning. nothing to worry about.
