When checking over your braking system, look for signs of cracks, wear, and glazing.


Gear oil is recommended to be changed once a year or every 50,000 miles. If you’re not sure, these are things that will indicate the need of a change. Check for water in the oil, as well as metal flakes or if the oil is blackened.


It’s been a terrible year for pot-holes and frost heaves. It’s a good time to have your front end checked (king pins, tie-rod ends, springs, pins and bushings) and aligned. Rear axles should have the U-bolts re-torqued or checked. The torque rods should be checked for worn bushings and the axle housing checked for cracks and then aligned.
