I have an 8.8 we are putting together and before we kill ourselves I thought I would pick your all's brains. I want to know what you guys have done to collapse the crush sleeve when the rear is OUT of the car on the floor. With it in the car it is no problem but with it out what is the easiest way to do it. My buddy does not want to use an impact thinking it could damage the bearings. So give me your ideas. Thanks.
