Buying a used differential: what to check
- Check gear ratio and ring backlash: Rotate the input flange to count ring-and-pinion ratios and check for excessive rotational play or binding between teeth.
- Inspect drain plug for metal debris: Pull the magnetic drain plug to look for heavy steel filings or gear teeth chips that indicate bearing or tooth failure.
- Confirm limited-slip versus open carrier type: Verify whether the unit houses standard open gears, a factory limited-slip clutch pack, or an electronic locker.
- Check input yoke and axle seal surfaces: Inspect seal contact areas for deep grooves, rust scaling, or oil leakage that will require new shaft seals.
- Refill with fresh specified gear lubricant: Install new axle seals and fill with fresh gear oil—adding friction modifier if equipped with limited-slip—before driving.
