Hey guys, I have a 98 xj and am getting a banging under my feet when hitting bumps and it is worse in four wheel drive. I originally thought it was a control arm bushing and have replaced all bushings. I have disconnected the sway bar and shocks and it still bangs. I have also checked the exhaust bracket at the cross member mount and that is fine. Any ideas would be great. I am thinking motor mount or tranfer case mount.
