Re: 2001 Grand has "thump" in rear end
 

Jeep is aware of this problem, my wife's '99 JGC had the same issue and our
2002 has it to a much rarer and smaller extent. It's something inside the
axle is all I can remember... they even replaced the driveshaft on the '99
trying to fix it. I think Jeep has a TSB on it.
