We have replaced (within two weeks) at least three remanufactured power steering pumps in our Chevy truck that were purchased from a local auto parts store. This new power steering pump is very quiet and even performs much better than the reconditioned ones. We are very happy with the consistent performance and impressively quiet operation of the Delco AC pump. Highly recommended! Save yourself a lot of hassle and frustration. Avoid cheaper remanufactured pumps and buy this pump.
