Do you have to wait to get the full weight of the car on the ground before you tighten up the upper A arm bushing bolts ?

I know you have to tighten up the lowers with full weight, but I wasn't sure about the upper ones.

By the way - air chisel or not those busings put up a good fight !

Thanks !

Rubber bushings should have the weight of the car on them before tightening,regardless of their location on the car. Polyurethane or polygraphite can be tightened weight on car or not.
