⚠ Important – VIN / OE Number Confirmation Required:
This rebuild kit fits differential housings matching the OE numbers listed above.
Please confirm your vehicle’s OE reference or provide full VIN before purchasing.

Installation Notes

Ensure all old bearing races and seals are completely removed before installation.
Clean the differential housing thoroughly to avoid contamination from debris.
Use a correct press tool to install bearings; avoid hammering the bearings.
Install oil seals flush and evenly; do not tilt or over‑drive seal lips.
Lubricate seal lips with gear‑oil‑safe lubricant before assembly to avoid dry start.
Set preload and backlash according to factory specifications post‑assembly.
Use GL‑5 mechanical differential gear oil; friction‑modifier additives are not required.
Ensure the breather is not blocked to prevent pressure‑related oil leaks.
Torque all fasteners to OEM specifications using a calibrated torque wrench.
After installation, test drive briefly and inspect for abnormal noise or oil leakage.
Re‑check differential oil level after 50–100 km of driving.
