Hi guys, there appears to be a groaning noise coming from the steering which is intermittent. It seams to moan when the steering rack is under stress eg. when the the cars weight is to the front as stopping on a hill, or while turning on a hill when the cars weight is at the back. I hope you can understand where I'm coming from. Apart from the pump is there anything in the rack that needs looked at. The car is a 1994 aero abbottised 106000mls. Any ideas.
