Tools and materials:
* New automatic transmission drive oil seal
* Gear oil
* O-ring for drain plug
* Set of keys
* Flat head screwdriver
* Hammer
* Installation tool for oil seals
* Brake cleaner
* Gloves
Steps:
1. Preparation:
* Raise the car and place it on stands.
* Install wheel chocks for safety.
* Remove the wheel corresponding to the drive shaft to be serviced.
2. Draining transmission oil:
* Locate the drain plug on the automatic transmission pan.
* Place a container under the drain hole to collect the oil.
* Loosen the drain plug with a wrench and allow the oil to drain.
* Replace the drain plug O-ring with a new one.
3. Disconnecting the drive shaft:
* Locate the drive nut on the wheel side of the drive shaft.
* Loosen the nut, but do not remove it completely.
*Using a hammer, gently tap the drive shaft where it connects to the wheel hub to disengage it.
* Pull the drive shaft outward to release it from the transmission.
* Cover the transmission hole with a cloth or plug to prevent oil leakage.
4. Replacing the oil seal:
* Wipe the area around the seal with a clean cloth.
*Use a flat head screwdriver to pry the old oil seal out of the transmission.
* Apply a small amount of transmission oil to the new oil seal.
* Install the new oil seal in place using an oil seal installation tool. Make sure it is fully inserted and flush with the transmission housing.
5. Drive shaft installation:
* Apply a small amount of transmission oil to the drive shaft splines.
* Insert the drive shaft back into the gearbox.
* Slide the drive shaft onto the wheel hub splines.
*Tighten the drive nut to the specified torque.
6. Refilling with transmission oil:
* Pour transmission oil into the gearbox through the filler hole.
* Check the oil level using the dipstick and add if necessary.
7. Assembly:
* Reinstall the wheel.
* Lower the car.
* Make sure all connections are tightened to the specified torques.
8. Check for leaks:
* Start the engine and shift the transmission into several different gears.
* Check under the car for oil leaks.
Additionally:
* For a more reliable seal, apply a thin layer of automatic transmission sealant to the oil seal seating surface before installing it.
*If you are not comfortable performing this procedure yourself, it is recommended that you consult a qualified mechanic.
