beware, they lie to your face tell you what you want to here take you money and then you are on your own. had two issues in 4 weeks on two different vehicles and no help what so ever. they rebuilt both differentials on one vehicle and we followed there guidelines , then 2 months later in another state stuck with a $3000.00 dollar bill to fix there mistake and all they did was blame us. bottom line it was installer error. second vehicle almost lost a wheel 20 miles after being picked up. to many people working there and no quality control anymore. they used to be good. but now just a chip on there shoulders and easy to pass the blame.
update, the better business bureau reviewed my complaint and ruled in my favor by there auto repair advisory committee, which is a panel of 10 shop owners and determined that we did everything that was asked. az diff still will not step up to the plate. no surprise apparently they have a hand full of complaints pending at the moment.
