I bought a 2006 grand Cherokee with 30,000 miles 2 months ago. Yesterday it developed a bad crunch/grind/pop which seems to be suspension related and feels like it is under the drivers seat area. It occurrs mostly after a stop when I begin accelerating. CRUNCH!
Doesn't act or sound like a U-joint, no rumble and lasts longer than just taking up some slack. It also happens sometimes when hitting bumps or dips in the road while driving. Feels like a good hammer tap under the drivers seat. Any ideas? I Gotta get under there tomorrow and look
