changing oil in the KF gear diff

[shaungooner]

Hi guys

just looking for a bit of expert advice on changing the oil in a gear diff

what do you use to clean away the oil already in there

I have a ball diff in my KF now and really like the way the car drives with that option but I'd like to experiment with diff oils to see if I can ahieve a setup I like with a gear diff installed

thanks as ever

Shaun
