Lexus 12157-10010 Rear Differential Filler Plug Gasket

Removal steps 1. Park on a level surface, engage parking brake, chock wheels, and wear eye protection and gloves. 2. Raise and support the vehicle with jack stands if needed to access the drain area; never rely on a jack alone. 3. Allow the engine and oil to cool enough to avoid burns. 4. If you want added safety against accidental starts or if working near electrical components, disconnect the negative battery terminal. 5. Position an oil drain pan under the drain plug, then loosen the drain plug slowly to control oil flow; remove the plug and let the oil drain. 6. Remove the old drain plug washer from the plug or oil pan mating surface; inspect for damage, debris, or metal particles. 7. Clean the mating surfaces on the plug and pan with a clean rag; ensure threads are free of old sealant or contaminants. Installation steps 1. Select the correct replacement washer type and size for your drain plug (commonly crush-type or bonded washers). 2. Place the new washer onto the drain plug seating surface so it will sit flush when installed. 3. Thread the drain plug into the pan by hand to avoid cross-threading, then snug it with a wrench until the washer is compressed and the plug is seated. 4. Do not overtighten; final tightening varies by design-use manufacturer torque if available or tighten only until the washer is properly compressed and no leaks occur. 5. Refill the engine with the correct oil and level, then reconnect the negative battery terminal if you disconnected it. 6. Start the engine, let it run briefly, and check the drain plug area for leaks; recheck oil level and retighten slightly if a leak is observed after shutdown. 7. Properly dispose of used oil and old washer, and lower the vehicle from the stands. Repair tip: Replace the washer every time the drain plug is removed; if the washer is a reusable metal type, inspect for warping or corrosion and replace if any defect is present.
