Driveline Overhaul

February 9, 2013

Whether you travel in a car, SUV, pick-up camper or expedition motorhome, it’s easy to overlook one of the smallest parts of the drivetrain. When you think about it, all of the power in our big engines is channeled through the transmission and back to the rear wheels (and front wheels if you have four-wheel-drive) through a bunch of little bearings, any one of which you can slip underneath your thumbnail. Those little bearings are located inside a fairly complicated system of driveshafts, CV joints and U-joints, all running on a thin layer of grease. If any one of these little components fails, you will know it right away because you will be on the side of the road. Periodically, and especially before a long adventure, we take our driveshafts to Drive Line Service of West Sacramento where they meticulously inspect, rebuild and balance everything with quality Spicer parts.

These little needle bearings are what connect your engine to the tires on the ground.
