I have a 2001 Chevy Suburban that kept making a rattling sound. I took it to 7 different mechanics, one of them was the Fairfield Chevy dealership that tried to rip me off by saying that I needed all the joints under the truck replaced. This was going to cost me $1700. I also took it to Ryan's Automotive in Fairfield and they said it was my catalytic convertor and that was going to be around $1600. I finally took it to Cme and they were able to determine with certainty what was wrong with it, the transfer case. They are very honest and knowledgeable people. - Soccer M.
