hey guys, i was screwing around with my pro4 at the track the other day. i was using rubber tyres and a 540J stock motor.
When i turned hard, the car spun around, because of the tyres being too hard. but when i spun around, and the car rolled backwards, it made a clicking sound!
on closer inspection (by turning the front one-way backwards while holding rear wheels, it did the same thing. i opened up the front diff case and there is absolutely no damage to the gears!
i remember putting some diff oil on the one-way bearings and i thought this could be the problem, because the outdrives are slipping on the bearing. could it be this, or something more major!?
Turns out, the small diff gear in the front was missing a few teeth
i have now put the old version gears into the front diff, will have to go and buy another set of the new version ones.
Does anyone have a good diff shim setup for the front and back? i am running the newer version gears in the back and the older ones in the front. i have a few silver and copper lookin shims lying about.
Cheers
