Rear axle "Green" bearings

Green bearings are a bearing made by the Green Ball Bearing Co.. They are a one piece sealed ball bearing used in place of the factory rear wheel bearing which is an open cup and cone style bearing. The sealed bearing pressed in place eliminates the need for a bearing preload adjustment/end play adjustment. The sealed green bearings are round (ball)versus the cylindrical factory bearing (cone). Because of this they are not as strong in a corner but have been used seemingly without issues on many a street car.
