T4 Geared Diff Advice
 

Who's running what as far as oils/greases in their gear diff's?

We currently run 7k in the front and 5k in the back....it was decent on worn grass and the combination seems to work ok on higher grip astro but we havent used the car all that much really :)

I also use the same oils as Iain, so far haven't felt the need to experiment with anything else

Brilliant, thanks for the info lads. Just cracked the ball diff thing, now got to learn gear diff's!!
