just a quick question, how much use do you generally get out of the car before the rear diff needs rebuilding, i have just rebuilt it with new washes and its crap, do the balls need changing everytime aswell??? it seems a right clart on, only been racing indoors, might go back to touring cars less hassle i think

are you running any diff seals - you know, the circle of vinyl type of thing that does its best to seal things up?

[big air]

no there's no seals in dont think the kit came with any, can you buy these for the yok or will others fit

Hi Steve,

You can make your own out of a sticker sheet or be lazy like me and buy Tamiya ones # 53970 - there are some on ebay if you do a worldwide search.

Cheers Jon

Do you have a picture that show how you seal the diff?
