I have a Land Cruiser 80 Series with a Lexus V8 1UZ-FE VVTi conversion. On idle, the power steering is not always assisting in steering, but as soon as the revolution go above 1000rpm the power steering fine. The pump was removed and tested. All seals were replaced and on test bench pump exceeds recommended pressures. What can I do to solve this issue the easiest way?
