I am getting ready to install DT axle arms that push the axle 1/2 an inch forward, to compensate for the leveling coils in front. How do I go about "pulling" the axle forward? Sounds difficult, and possibly dangerous. What or how have those of you who have done this before achieve this? Also, do you do the 2 uppers first, since they don't move their position, then do the lowers or vice versa? Any help would be greatly appreciated! Thanks!
