Well I got tired of the noise from the power steer pump and also the belt tensioner. I purchased both and used factory parts. Made a big difference as she is now nice and quiet with no grinding or whirring noises. Bit of a dirty job but well worth it. I also flushed the power steer system and it now has synthetic so hopefully I wont have to touch that again? I flushed the power steer system by removing the return hose plugging the tank and without the engine going went lock to lock. While the old crap came out I was filling the resevoir with fresh synthetic. The old crap was simply pumped out of the return line into an old oil bottle. Definatley worth the effort as the steering is now smooth and quiet!The belt tensioner was also repalced as that too was noisy and almost grinding.
