1998 Lexus LS 400 V8 Two Wheel Drive Automatic 83,454 miles
My lexus is making a thumping sound when accelerating. We have replaced the differential and the problem still persists. We lifted the car on a vehicle lift and accelerated and noticed the rear wheels were turning intermittently. Upon further inspection we noticed the brakes were locking up and releasing and locking up again. We removed the ABS relay and ABS Solenoid relay and the wheels started turning freely again. The problem is we do not know what is causing this and removing the relays has not solved the problem completely as when we accelerate on the ground the thumping still continues off and on and the car seems to be dragging or feels heavy. Can you help me?
