Hi Scotty love your videos. My question is I have a deep groan when turning the steering wheel from right to left (usually when the wheel goes past centre position ) but doesn't happen from left to right. The noise goes away when the car is jacked up. What's your guess? Thanks in advance :)

Could be a number of things from loose belt, low fluid, bad pump, bad tie rod, bad ball joint, bad strut bearing - guess? bad joint

Thanks for your speedy reply Scotty. PS your trans tune for power steering video completely solved my sticking/slipping power steering. Smooth as butter now (apart from the groan haha). Have a great day.
