Hey guys (and gals if there are any of you out there), I have a 1974 Challenger with a 3.23 sure grip rear end. I notice when in forward or reverse at very low speed (like less than 1 mile per hour) and especially when turning, I get a clinking feeling, noise and actually see the rear wheel girate a little. Is this normal; ie. does it just do this because one wheel is turning faster/slower than the other, or do I have a potential problem? Thanks everyone. Charlie
