Replace the rear differential center case
Remove the dirt and oil from the sealing surfaces Apply liquid gasket (P/N 08717-0004, 08718-0001, 08718-0003, or 08718-0009) to the sealing surface Make sure you seal up to the inside edge of the bolt holes to prevent oil leakage
NOTE:
- You must assemble the housings within 5 minutes after applying the liquid gasket If you applied liquid gasket P/N 08718-0012, the component must be installed within 4 minutes If not, the sealing surface must be cleaned, and the liquid gasket reapplied
- Allow the liquid gasket to cure at least 30 minutes after assembly before filling the differential with fluid
