- Disconnect the negative battery cable from the battery.
- Raise and safely support the vehicle on jackstands.
- Drain the transmission fluid into a large container — refer
to Section 1 for fluid draining and refilling procedures. This would be a
good time to change the transmission fluid filter.
- Matchmark the driveshaft (matchmark both on 4WD vehicles).
- Remove the end of the driveshaft not attached to the transmission, then
pull the driveshaft out of the transmission (also transfer case on 4WD).
- Remove the dust seal guard (if so equipped), then pry the oil seal out of
the extension housing or transfer case with a seal remover or prytool. Be
careful not to scratch or gouge the sealing surface on the inside of the transmission.
To install:
- To install the oil seal, apply transmission fluid to the lip of the oil
seal. Install the new seal with the lip toward the front of the housing (facing
into the transmission). Use the Mitsubishi tool MIT3995 and MB990938–01
to install the seal. If these tools are not available, a large socket the
same size as the seal can be used. Use a plastic or rubber mallet and do not
hit the seal too hard, damage could result to the transmission and to the
seal. Seat the seal until the seal is flush with the transmission seal boss.
- Tap the dust guard back onto the transmission extension.
- Slide the driveshafts back into the transmission and transfer case so that
the matchmarks line up, then attach the other ends to the differential units
or center link.
- Fill the transmission fluid as per Section 1 in this book.
- Make certain everything is in place and tightened securely, then lower the
vehicle.
- Connect the negative battery cable back to the battery.
- Start the vehicle and allow it to warm up. Check for any transmission fluid
leaks from the fluid drain or fill holes and from the oil seals.
