Brought my in my 2006 F150 for noise coming from the rear end. I tried to self diagnose and fix with changing out the fluid in the rear differential but that did not get rid of the noise. After checking other components that could have been causing the issue I gave up. I had read all of the positive reviews from others about Valley Automotive and dropped it off. They first did their courtesy inspection along with a detailed report which I was not expecting but appreciated since I recently purchased this vehicle used. They found this issue and gave me the bad news, best case replace pinion bearing worse case replace the entire axle assembly or rebuild differential. After further investigation the found that it was much more damaged than I thought. Bryan called to provide the bad news and went through the photos of the damaged components that were added to the report. I had them replace the entire unit with a Jasper remanufactured differential along with new axles. With only 92k on the truck I felt it was totally worth it. When I picked up the truck and payed the bill it was less that I what I had written down from the estimates given over the phone. Bryan always returned my calls and answered any questions I had. The final bill also had a second page that listed all of the future services my truck will need along with their cost which will help me budget and choose what to have done in the future. I would highly recommend.
