Todd, the shop I go to charges $400 parts and labor, just to do a gear swap, using Motive Gear gears. However, I had the Traction Lok rebuilt with new clutch packs, bearings, seals, and Royal Purple gear lube, and the gears of course, done for $675. I'm extremely happy, and there is absolutely no noise. This is in North Carolina.
