How big are the bolts to that hold the front ends of the rear lower controll arms? And is it ok to remove those bolts without supporting the controll arms?

 

I don't remember the size of the bolts (3/4" - 7/8" or something) but you can remove them without supporting the LCA. Just put jack stands under the rear diff and do one side at a time. If you remove both LCAs it can be difficult to get the rear lined up again when reinstalling them.

putting jack stands under the rear and unbolting the control arms is a BAD idea!! you must support the chassis with the stands, then use a jack to support the rear while removing the arms
