Leaking Rear Differential

Pic 1: Leaking rear differential

Noticed that the ER34 has a leak on one side of the differential. Nothing major, just a leaky differential seal. So I got the car jacked up and the differential removed. Whilst only one side is leaking, well one might as well replace both sides of the differential seals since it's already removed from the car.

The ER34 uses the "Rear Differential Seal-Side, bearing the part number 38342-N3100". Ordered two of them and it was replaced after all the existing oil was drained out. I took the opportunity to change my differential oil while at it. Motul Motyl Gear SAE 80 W140 was ordered and in it goes into the differential.

Now it's as good as before. There's still some work to be done to the ER34. Will update as and when I get around to do it. Looks  like 2013 will see a bit of more work done to the ER34. :)
