Took my truck (2007 GMC Sierra 4.8) with a very noticeable vibration occuring in the front end. Truck was diagnosed within the next day (dropped off at 2pm, diagnosed by 9am next morning). Mechanic personally called to tell me it wasn't CV or bearing related, could have easily sold me into it unnecessary work. Suggested an alignment and wheel rotation, and was ready by 11am. What could have been 1000+ was less than two hundred bucks. Honest mechanics are rare and should be recognized. A+
