Hello to all and thanks in advance for any and all help provided. I own a 2000 Yukon Denali project. I can purchase a complete rear axle from a 2004 Yukon for 250.00, this would provide the rear disc brakes I want. Is this a feasible swap and should I consider any precautions. I know it has the same gear ratio of 3.73, and am unsure if a locker or a limited slip, which would be bonuses!! Thanks again for help from the guru's
