Tie rod - Toe-in Allignment

Improper toe settings may cause your vehicle to handle strangely and wear out its tires rapidly.
Only 1/8 inch of toe misalignment front or rear produces the equivalent wear of scrubbing the tires sideways 28 feet for every mile traveled.

Excessive toe-in causes tire wear on the outside of the tire and can also make the car oversteer and dart back and forth across the road. Excessive toe-out causes wear on the inside edge of the tire

Remember, worn outer tie rod ends are a major cause of abnormal tire wear, as toe cannot be accurately set when these components are worn. So replace tie rod ends of there is play.

Changing Differential Fluid

Owners manual says to refill F&R axle every 12K miles under heavy use (off-road, towing, ...), but doesn't give an interval for normal use.

At GetAHelmet.com/jeeps/ they say:
I try to change my diff fluid in my rear axle at least every 15,000 miles and around 30,000 on the front axle since it is only under load during the occasional 4x4 trip.
