how do ou use the front shock adjusters? should they be able to be adjusted b hand or do you need an adjustable wrench? i tried and mine are stuck. i'm gonna buy a set of adjustable wrenches real soon so i'll try it then. in the shop manual, it just says to rotate them to the desired postion and nothing else. i know the back ones need a wrench to be moved because they have nuts involved, but the front adjusters don't.
