St.Clair Co. IL. | If your wondering about adjusting first I block the front wheels jack up the rear wheels one at a time on the back of the slack adjuster there is a 3/8 (usually) bolt head push in on the lock and turn clockwise while turning the wheel by hand if you have the self adjusters just turn slowly till the wheels start to drag then stop if they are not turn till tight then back off a quarter turn and go to the next one repeatly the procedure hope I helped some.
