I took my Jeep to Brian and Jim's shop a month ago because I heard a grinding noise at about 20 mph and above in the general area of the rear wheels. I talked with Brian a several times and he seems to be a knowledgable and good guy. They found a used "rear end" and installed it at what seems like a reasonable price. Jeep sounded great when I got it back. It's now two weeks later and the same (or similar) sound is back. When I called Brian said essentially, "Bring it right in and we'll take a look." I like this shop.
