Drivetrain

Gear Oil Flushes

The internal gear sets found in differentials and transfer cases operate under immense pressure and shear forces. These components rely on specialized gear oil to provide a protective film between metal surfaces and to dissipate the heat generated during power transfer. As this oil ages, it becomes saturated with microscopic wear particles and loses its viscosity, which increases friction and leads to premature gear wear. A professional gear oil flush removes these contaminants and replaces the old lubricant with high-performance synthetic fluid. This service is essential for maintaining the smooth operation of all-wheel drive systems and preventing the whining or grinding noises associated with differential failure. Proper lubrication in these units ensures that torque is distributed efficiently to the wheels without mechanical hesitation.

Axle Assembly Replacements

The axles and Constant Velocity (CV) joints are the final link in the drivetrain, responsible for transferring torque from the transmission to the wheels while accommodating steering and suspension travel. These assemblies are protected by flexible rubber boots that keep grease in and contaminants like dirt and water out. If a boot tears, the lubricating grease escapes and road grit enters the joint, leading to rapid wear and eventual failure. You might notice a clicking sound during tight turns or a vibration at highway speeds when an axle is compromised. We provide precision replacement of the entire axle assembly to restore the smooth delivery of power. This proactive replacement prevents the risk of a broken axle leaving you stranded and ensures the integrity of your vehicle’s drive system.

Drive Shafts and Wheel Bearings

While axles handle the lateral transfer of power, the drive shaft is responsible for the longitudinal delivery of torque from the engine to the rear or all wheels. The universal joints and center support bearings on these shafts can develop play over time, leading to a distinct clunk when shifting into gear or a high-frequency vibration during acceleration. Similarly, wheel bearings support the weight of the vehicle while allowing the wheels to spin with minimal friction. A failing wheel bearing often creates a low-pitched humming or growling noise that changes with vehicle speed. Inspecting these components alongside axle service provides a complete picture of your vehicle's drivetrain health and prevents secondary damage to the transmission or differential housings.
