Differential Repair and Maintenance

The differential and axle system handle heavy torque loads and keep power delivery smooth and controlled. When differential problems develop, they can show up as whining or humming noises at specific speeds, vibrations under load, clunking during acceleration or deceleration, oil leaks at seals, overheating, or metal contamination in lubricant. Left unaddressed, differential wear can damage gears, bearings, and axle components, leading to major downtime and expensive repairs.

Our differential service starts with careful evaluation of noise patterns, lubricant condition, leak points, and driveline behavior. We inspect seals, check venting, verify fluid levels and quality, and assess bearing and gear condition when symptoms suggest internal wear. If a repair is required, we focus on correcting the root cause, whether it is lubrication breakdown, improper setup, contamination, or progressive wear. We also examine related components such as universal joints and driveline angles, because driveline issues can imitate or accelerate differential problems.

Preventive maintenance for differentials is one of the most cost effective ways to avoid catastrophic failure. Regular fluid checks, leak repairs, and timely service protect gears and bearings and support smooth, efficient power delivery. When properly maintained, the differential runs cooler, stays quieter, and delivers consistent performance under heavy loads, which helps fleets and owner operators protect uptime and extend the life of the entire drivetrain.
