Keep the vehicle under 60 MPH for the first 100 miles
Drive 15 to 20 miles, stop let differential cool before proceeding
Drive at least 500 miles before towing. First towing should be less than 15 miles, then let cool before proceeding
Change Gear Oil after the 500 mile break-in, this removes metal particles and phosphate coating from the gear set during the break-in period.
