Okay, So I've had my Jeep Liberty for about maybe 7 or 8 years. Just about a year ago I started having trouble, i used to drive her off road nearly every chance i got, i took dirt roads, and basically fell in love with it so i spent most of my time finding ways to keep it at its peak performance, but I've noticed a bone grinding sound coming from either the front left or front right wheel when i turn or press on the breaks. We've replaces the calipers, even new brakes pads, and we still can't seem to find whats wrong with her. Some say It's the ball bearing, and some say its the rotors but I'm not wasting nearly $500 just to have it checked out when i could find out what MIGHT be wrong with it from this forum. Btw everything on her is completely stock, I just upgraded the spark plug connectors, distributor, new alternator, and soon I'll be getting new headers and Cylinder rings. Please help! I don't want to keep putting my Jeep through this!
