1. Loosen the rear wheels bolts then place the rear of the
car on jack stands. Clean the differential if there is a lot
of dirt and oil around.
2. Grab your favorite oil pan and place it under the differential.
Locate the drain plug and drain the differential oil.

3. Take a socket Allen key and remove all the
bolts holding the half shaft. To do so, I place the car in 1st
gear, loosen a bolt then remove the car from gear, turned the
wheel, place the car in 1st gear again, loosen another bolt
and so on...
4. once all the bolts are removed, place the half shaft out
of the way and secure it with a piece of wire. |
4. Pry the drive flange out with a big screw drive
or a little pry bar. You have to use a piece of wood for leverage
else you might damage the differential.
5. In the picture you can see the seal. To pry it out, you need
a seal
puller (cheap tool), don't even try with a screwdriver,
there is a big chance that you won't be able to remove it... |

5. Once the seal is out, in the picture you can see the
snap ring. This is a good thing to change while you are
changing the seal. Use a small flat screwdriver and remove
it.
6. Install the new snap ring in place.
Snap rings failure will make the flange pop out on its
own and you will loose a lot of differential fluid.

|
7. Lubricate the new seal with differential
fluid and carefully install it in the differential. You can
use a big socket and a small rubber hammer to make sure that
the seal is in place. Be careful as you can VERY EASILY damage
the seal... It is a good thing to buy an extra seal just in
case.
8. Install the drive flange back in place until the snap ring
engages.
9. The rest of the installation is reverse of removal. Don't
forget to fill up the differential with fresh redline gear
oil.
