Heck I've been missing a front end link for a couple of months and other than some more ody roll in corners it's fine...even on the highway at 130.
I was missing one of my fronts for awhile as well, being secure on one side eventually bent my sway bar. I had to use JKS adjustable ones for stock to 2 inches of lift to get them to fit. One side stock level, the other had to be maxed length.
Be careful thou, running no front links severely alters maneuver response time, with dangerous body roll. Personally I would not run intentionally without the front links, and would not run at all if there where no rear or front links. Unless it was a trailered non pavement bush toy.
Thought I'd throw that out there for anyone thinking it was cool to lose them.
