Im just a n00b to LC's, but instead of tie rod ends, what would replacing them with sperhical rod bushings do? You could buy blanks, and drill and tap to fit your linkage... The only pic i know of is the ones for my stang, so this is what they look like, but not specific. http://www.partshopper.com/shop/Steeda-Bump-Steer-Kit-79-04-Mustang-m139.html
I know they helped my steering, but i haven't checked to see what they may do in offroad platforms.
