- Locate Drain and Fill Plugs: For differentials, these are typically on the cover or housing. For manual transmissions and transfer cases, they’re usually on the side. The fill plug is almost always above the drain plug. Always remove the fill plug *first* to ensure you can refill the unit once drained.
- Drain the Old Oil: Position your drain pan directly under the drain plug. Carefully remove the drain plug. The oil will likely be hot, so wear gloves and eye protection. Let it drain completely, which can take 15-30 minutes. Inspect the old oil for metal shavings, which could indicate internal wear.
- Clean and Replace Plugs: Once drained, clean the drain plug and its mating surface. If your vehicle uses a crush washer or gasket, replace it. Reinstall the drain plug and tighten it to the manufacturer’s specified torque.
- Refill with Lucas 80w90 Synthetic: Insert the fluid pump hose into the fill plug opening. Begin pumping the Lucas 80w90 synthetic gear oil. Continue filling until the fluid just starts to trickle out of the fill plug opening. This indicates the correct level.
- Secure the Fill Plug: Remove the pump hose, clean the fill plug, and replace its gasket if applicable. Reinstall the fill plug and tighten it to the manufacturer’s specified torque.
- Final Checks: Lower the vehicle if it was lifted. Check for any leaks around the drain and fill plugs. Take a short drive, then recheck for leaks.
Crucial Safety Tips and Pro Advice
Safety is paramount when working under a vehicle. Always use sturdy jack stands and never rely solely on a jack.
Wear appropriate personal protective equipment, including gloves and safety glasses, as gear oil can be an irritant.
Always refer to your vehicle’s service manual for specific torque specifications for drain and fill plugs; overtightening can strip threads, while undertightening leads to leaks.
