Right rear sticking

Bad Sport said
Not really sure, but the symptoms started after the changes.

I hope you find the issue in the wheel cylinder, that's a good place to start.

I know after I messed with my suregrip, it was so tight for a while it was like I had a spool in there. Going around corners it would hitch and almost feel like one wheel was locking up.

Im hoping for the wheel cylinder to be my problem as well.. Heres how the gear swap happened.. I had a 742 case with .355's in the Dart.. My buddy had a 741 with .391's in his Cordoba... He bought a set of .430 gears but needed my 742 case... so we swapped.. I have been in his car many times.. His rear made no noises, sure grip worked perfect.. So I am not leaning towards the gear swap at this point.. I am gonna start with the wheel cylinder and work my way in if I need to
