I am Chris Gordon the owner of C & M Gearworks. I would like to respond to ""Honest reviews"". He brought his truck in on 8-23-2006 to change the ratio in his Dana 80 from 4:10 to 3:73 to try to get better fuel mileage. His total bill was 849.47 which included a Dana gearset, complete bearing kit, labor and grease. A far cry from the $1500 he claims he spent at CATT. He did leave his old gearset with us but made no mention of hanging on to it for later use. On 11-10-2006 he came back to go back to 4:10's as the 3:73's didn't help his mileage and the 4:10's pulled his big bumper hitch trailer better. I told him since we had either used or sold his old gears I would just trade him straight accross for the 3:73's he had in there now and only charge him $300 labor. Everything was fine until 7-29-2009 when he brought the truck in with the gearset and positrac differential destroyed. We completely rebuilt the rear end with a new Dana positrac, Yukon gearset and bearing kit, along with Lucas synthetic 75-140 gear oil and Ford positrac additive with a total cost of 1328.99. He did bring the truck back several times to have it checked and all we ever found was the gear oil was as thin as water, and some loose hub bearings which he didn't seem concerned about fixing. We even installed an alluminum rear cover for added capacity and better cooling. So when he came in earlier this year after nearly 2 years and 60,000 miles and said ""the rear end is out again"" and that his friend or neighbor had diagnosed the problem I suggested maybe he should have him fix it, and that I had no interest in working on his truck again. If there was a problem with our work or our products it wouldn't have taken 60,000 miles to go out. This guy is the exception and not the rule with our customer satisfaction. I have a feeling he won't be happy anywhere for very long.
