I have a problem with my 97 Range Rover 4.0 drive system. Each time I want to turn, the wheels kind of seize. This damages the Universal Joints, which I change atleast once a month. It only happens when the steering whell is turned, either going forward or backwards. Its like the front wheels want to go forward and the rear wheels in opposite direction. I have replaced both differentials to no avail. I hope somebody has experienced this before. I hate to sound stupid!. And please dont advice me to see a main dealer. There is none here in GAMBIA
