LSD oil change
 

Apologies in advance for my stupid question.

How do i change the Diff oil on my 7? I have an aftermarket LSD.
I have searched but couldn't find anything
Many Thanks

There should be some sort of drain plug at the bottom and then a fill plug on the side somewhere. Drain and refill with the proper amount. Since you have an aftermarket unit you may need to call the manufacturer to find out the capacity.

You will either need some kind of pump to get the new gear oil into the differential, or you can use a funnel and a long length of plastic tubing. The tubing/funnel method has always worked fine for me. Put one end of the tubing into the fill plug (after replacing the drain plug) and snake the tubing up through either wheelwell and hold the funnel and tubing above the level of the diff. Pour oil in until oil begins to flow out of the fill plug hole. Verify level with your finger, and close the fill plug.

By the way, make sure the gear oil you choose meets the manufacturer's specifications in terms of weight and that it contains limited slip additives.

or u can buy the friction modifier separtely but dont forget it

Thanks for your help guys will give it a try
