I have a 2003 S2000 may have been abused by previous own. Have been noticing a shudder in the rear end when leaving out of a stopped position while turning. This does not occur unless I have been driving for at least 30 minutes. Any ideas?

 

Last time you changed the diff fluid?

What fluid is in it now?

If you just got the car, and aren't certain of the answer, change the diff fluid and see if that makes a difference.

Note the color of the old fluid and if any particles on the drain plug.
