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 liquid gasket to cure at least 30 minutes after assembly before filling the differential with fluid.
