Differential Servicing

grslightng02 · 10-19-2008

I seached the posts and did not find the information I was looking for. I thought I had once seen a posting mentioning two bolts on the differential, one to fill and one to drain? I'm only finding one bolt in the back of the differential plate.... so I'm confused where you fill and drain the differential.

Chilton manual and Opel GT manual don't help much. Can someone please post the correct procedures for changing/adding differential fluid and any pics that might be helpful.

Thanks, Neil

Neil;
The "drain" hole is the lowest bolt holding the cover on the diff. The "fill" hole is the plug that is in the cover about the 3-4 o'clock position.

Let it drip for a few hours

, the only bad side about it is filling it again

fill it up until the oil comes out the filling hole
