For my fellow Midwest members. Wondering if anyone in the Midwest (N/E Illinois area) can point me towards an excellent quality re-gearing/driveline shop. Will be re-gearing to a 4.56 or 4.88 this winter and am having trouble finding a reputable axle shop that can be trusted to do a perfect gear swap (Dana 44 ADVAN tek). As Overland travel requires our rigs to stay reliable for very long distances, I do not want my swap done by someone who does it "on the side" or a shop that is a general "do all" shop. I know gearing has to be done absolutely right to be trouble free. Any recommendations would be a great help. Thanks for the assistance!
