Peter:
Next stop would be to check subframe bushings and specially the large
bolts tightening the sub-frame to the frame. Some people have reported
elongation of the hole in the frame allowing some play to the sub-frame
bolt depending on force of traction, turning or breaking. Quick fix,
welding a healthy size/thickness washer, to provide a firm fixed hold
for the sub-frame bolt...Check it out
