1. Put together the gears in the case
make sure you have the housing gasket that goes between the housing and the case. I also used silicone to insure a good seal
green bearings are just sealed bearings all one piece as opposed to the original style tapered bearings. Make sure you have them pressed on by a shop. it should be just the metal plate the bearings and the collar
much easier to get the gears bolted to the housing out from under the car. the axels could be put in when it is already sitting on the leafs
