Differential Reconditioning to Restore Functionality and Performance
Our differential reconditioning service revitalises your existing differential by removing worn components and replacing them to restore smooth function and prevent costly drivetrain failure. Reconditioning can help you avoid purchasing a brand-new differential while improving vehicle reliability and reducing noise and vibrations. This service is essential for keeping your drivetrain in top shape, especially if your vehicle endures heavy loads or rough terrain.
In-House Parts Rebuilding for Quality and Precision
At D & R Differentials, we offer in-house rebuilding of crucial differential parts such as crown wheels, where tooth damage like shear-off can occur, as well as seals and bearings. This ensures every part meets our high standards and fits perfectly within your differential assembly. Our skilled workmanship guarantees durable repairs that restore the integrity of your drivetrain.
Reasons to Choose Differential Rebuilds Over Replacement
Rebuilding is particularly valuable for early-model vehicles where parts may be scarce or difficult to source. It is also necessary when undergoing gear ratio changes to optimise vehicle performance. Rebuilds save you significant cost, keep classic and custom vehicles on the road longer, and allow customised upgrades to meet your specific requirements.
Common Signs Your Differential Needs a Rebuild
Watch for clunking noises when shifting between drive and reverse or persistent whining and humming sounds from the drivetrain. Fluid leaks around the pinion flange or axle seals are warning signs, as are vibrations or shuddering through the floor under acceleration or while carrying heavy loads. Early diagnosis and rebuilds can prevent total drivetrain failure and costly breakdowns.
