3:23 Limited Slip

I replaced my 2:76 with a 3:23 limited slip about a week ago. I bought it off someone I really trust. It seems fine except at really slow speed like when parking. I'm noticing a chattering while turning almost like an old school 4WD on dry pavement ( but only a tenth as bad). Actually its very slight but its there. I also feel it in reverse. I'm using Lucas SAE 80W-90.
