I've always had great service from Scott and his crew. The rear pinion bearing and seal went out in the rear differential in my 2005 Yukon XL. I had this replaced by them in December 2016. They replaced these for free as it was under their 2yr/24K mile warranty. In addition, there was another part that failed (a yoke) that they determined was the root cause of the problem. They replaced that part at a very reasonable cost. They stood by their warranty and now it shouldn't happen again. Very satisfied! I will continue to take my vehicles to Valley Auto Care.
