Ken's located a very hard to find squealing noise from under my vehicle. I thought the repairs were pretty expensive until I found out that the replacement part (from the manufacturer) was the entire drive shaft, support bearings, and support brackets. I was very pleased that they even showed me the old drive shaft and pointed out the problem area and other wear points that they noticed. Ken's continues to give me excellent, fast service and fair prices. They even sent a courtesy driver to pick me up so that I could retrieve my vehicle.
