i just picked up a used summit and was wondering what everyone uses to take the lug nuts off for the tires, also the guy has two steel drive shafts installed and two stock ones still on it but he gave me the other two metal drive shafts, but the weird thing is the two drive shafts he has on the summit are the front passenger side and the rear drivers side, any one know why and should i just install the other two or just leave them thanks all
