"last ?" lol....i dont mind helping folks as long as they arent annoying and rude (no offense "like Hart") but you havent been.......yeah i dont understand and have tried to figure out why James had caster problems.......caster really isnt that big of a factor unless its positive or set to 0, which would be really hard......and another thing camber doesnt affect caster so there isnt a real explaination as to why James had problems, even with the extention, unless something was extremely wrong somewhere. but yes you can order the upper arms from djm (2000 ranger 2wd ext. sport, to be exact is what i used) they should all be the same but just incase thats what i used, i installed mooog balljoints in them bc you get more movement. Raised the upper arm with 2x4 tubing 3/16" thick i believe (2" high). Ok heres the tricky part i used ranger balljoints which is what you are goin to have to use, the overall diameter of the balljoint(the width) that attaches to the spindle is smaller than an explorer balljoint. It will seem to fit fine in the spindle and lock into place but its really not its loose if you hit it kinda hard with a hammer (other words like hitting a pot hole). This cannot stay that way or youll end up rolling it bc it rips out. To fix that problem, on the balljoint, on the top part meaning the part that sits into the spindle above the lock in bolt, lay a weld bead all the way around it, and so forth on the bottom of the balljoint that fits into the spindle below the locking bolt. Grind the weld down until it fits snug into the explorer spindle, in other words i being the same size in diameter as the explorer balljoint...................ok this is alot of stuff so read it carefully and reread it before asking ? again bc it should click with you unless you are totally confused.....let me know through my email with any further ?'s please...ill respond better and quicker on there. let me know!
Thanks,
Matt
