I have a 99 Grand Cherokee limited, the v8 4.9, and it has started this loud clicking and rubbing sound when turning sharp turn. Its completely stock and im not great at diagnosing problems. I read it might need diff oil and I checked its fine, but its a grinding sound and it sounds to be getting worse. Any idea or a place to start would be really apprieacted.

 

Also it has that quadradrive if that helps

 

I'd check the CV or U joints.. whichever you have. While you're under there, you might also check the plastic wheel well liner. I've seen them come loose and rub the front tire.

 

My wife just told me sometimes it prevents her from turning the wheel all the way over.to the right.

 

You might get a response if you post this in the GC section since this id for the XJ's.
