Hi y'all, my mad rat had a noisy drive train , when i took it apart i found that there was only one ballrace in the diff when there should be two, this was allowing the diff to flex and causing a loud noise when accelorating hard, once i replaced the missing bearing it ran very quiet and smooth,there wasnt any thrust race grease in the kit so buy some of that or the thrust race will simply wear out in a few runs.dont waste money on a tiny tube just go to your local hard ware store and get some molybdinum grease, once assembled and set to the correct point fit a foam plug in the outdrive to seal it from the elements and to hold the grease in the thrust race . i found the best diff setting was with the nut retainer that is visable in the outdrive set to about 2.5mm from the inboard end of the outdrive slot, this should give a good free diff with with zero slip and a touch of on power oversteer on grass track with stock kit tyres (that work really well on wet grass ! ),, also i found that i had to run the slipper very loose ( but still enough to move the car) for half a pack then started to adjust from there as the slipper takes a while before it beds in , more like a gripper than a slipper when it was new, .
