went to Oasis for regular oil change, and asked Tony to check u-joints or carrier bearing as I was hearing a clunk upon acceleration, a similar sound to u-joints going bad. Tony went for a ride with me, then got under the truck and checked for bad motor or transmission mounts, and the u-joints - all ok. When doing the oil change the next day, they dropped the rear of the drive shaft to check it - nothing unusual. all done at no charge except the basic oil change. Whatever magic Tony has - the clunk (that he heard + felt too) is gone. \nwe trust this shop with servicing our vehicles, and really appreciate their customer service.
