I just had my rear diff serviced.My pinion seal was leaking and spraying gear oil all over the undercarriage.My mechanic said the yoke was screwed and he showed me how it had a groove cut in one side of it.I guess it was wobbeling or something.So now it seems my car doesnt spin as bad from a stop.Is it possible that with the work done I better better traction now?Sorry if that sounds stupid but its either that or I`ve got another problem going on cause it`s not burning up the tires like before and I may have a part throttle and low rpm miss cause after a second it comes alive again.Thanks.
