Hi,
I've just finished fitting a whole new rear diff setup in my Kraton. I've kept the old diff housing, but I've put a brand new set of bearings, a new diff cup and out drives. I've even replaced the spiral gear to the center prop shaft out drive and added new bearings.
My issue is that the mesh on the crown gear feels really poor, it has some play in it, but it is really noisy spinning one way and not too bad the other. I've added two shims on the crown gear side to help push the crown gear towards the spiral gear. I've tried it with 0 shims and it feels a little worse and I can't get 3 to fit in, so I'm stuck at 2.
Does anyone have any suggestions, the old rear diff was ok, but the spiral and crown gear were worn away a fair bit so I don't want to see this happen again, but that seemed to be caused by a bearing failure at the spiral gear on the center drive shaft out drive. The diff housing looks ok also?
I should also note that the rear diff is not yet been fitted back into the car, it is rough and noisy just turning it by hand. I have tried leaving some play in the center drive shaft out drive and also tried it right up tight against the bearings, without much change. I've greased the gears, but I just feel it doesn't seem smooth enough. I hope I'm not being paranoid, but I don't want to strip these gears, as I've just bought them and are brand new.
Thank you.
