  • Most folks never consider rear differential service until one of two things occurs

    A leak or a noise. Both problems are actually symptoms and many times both could have been prevented. Our philosophy is to prevent expensive breakdowns, rather than only treating them after they occur.

  • Can service the rear differential in your vehicle, checking seals, the vent and replacing the lubricant.

    We have found rear differential fluid, like all lubricants, breaks down over time. As lubricants lose their ability to protect, damage occurs. We use Mobil One fully synthetic lubricants to protect your investment.

  • Much damage also occurs because of damaged and missing vent hoses.

    All differentials build pressure when operated. This pressure is vented to prevent damage to seals. The vent is normally connected to a rubber hose, preventing water from entering the differential when driving in the rain. Over time these hoses crack and often come off. This allows water to emulsify the lubricant and quickly destroys the differential.

  • Performing a differential service can prevent this and many other problems.

    Spotting a dry-rotted vent hose and replacing it may be a small thing, but it can prevent a huge problem.

  • Even when a problem occurs, such as a whining noise on acceleration, quick action can drastically contain cost.

    We can often replace bearings and seals, restoring the differential to original condition. Left un-repaired, the bad bearing quickly degrades to a ring and pinion replacement, which is far more expensive.

  • Whether a fluid change

    Leak repair, upgrade to a locker, gear ratio change or total rebuild, let one of our highly trained technicians take care of that differential problem.
