Although Pole120 has a lot of knowledge,he is not completely accurate on this subject.You can install the bushing with the sleeve,and while on the car.Get a bushing removal tool.It is a set of "cups" used with a c-clamp, that support the bushing as it is pressed into the hub.I have done this on my car.The best way to get them into the hub is to bevel the edge of the bushing that is going through the hub.Then apply A LOT of lubricant.If you want more info shoot me a PM.
