I've been wanting to change the gear lube in the rear axle of my '01 3500 as it's coming up on 180,000 miles. With the pulling I do I thought maybe this might help my mileage and reduce heat. Anyone have experience and what are you using? Also will synthetics have the additives for limited slip diffs?
