I have been searching all over Vancouver, WA from shop to shop and everywhere I go they want ridiculous amounts of money to do the 3.73 rear end swap....I haven't had luck finding anything under 1000 dollars...this just seems outrageous...and all the stores say they won't perform the swap without installing new bearings...as long as my current bearings are in good shape do I really need new bearings I mean the parts will be the same size just the gears will have a higher ratio of teeth so to me the bearings seem pointless....am I wrong? Can anyone help me find a decent price on install?
