  • Weird grinding at low speed

    Sometimes when I'm maneuvering at very slow speeds I hear a strange grinding coming from the rear wheels. I'm thinking this is a hub mount issue (the lugnuts may not be torqued right) but I always torque them down heavily in a star-shaped pattern.

    Could this also be a rear-end issue? I tend to think not because the car had this issue when I had it dynoed and the rear end held up fine.

    Any advice would be helpful.

    It could be the rear brakes. Do you have drums or discs in the rear?

      could be a few things. do you have a limited slip diff? if so did you add lsd additive last time you did a fluid change?

      do you have rear disk brakes? or drums?

        That's a new one, what torque value is that? :p

        Anyways, I'm with the other guys that it's either the brakes rubbing or diffy. If you have rear discs the play in the axle c-clips can cause the pads to drag. Pulling the calipers, then cleaning and relubing the caliper slides can help.

          ^^^ LOL that's called doing it by feel.

          I don't know if they put additive in.

          I have disc brakes in the rear.
