My brother has a pretty darn righteous CJ5 he bought a couple years ago. It is a REALLY nicely built rock crawling rig he bought used. Off road, it is AMAZING. On the road it is really sketchy. To the point that his wife won't ride in it and doesn't like the kids riding in it (on the street). We are trying to think of some ways to improve the street driving characteristics.
First some details:
73 Cj5, 350, TH350, NP205, fully boxed frame, GM 10 bolt front with Detroit locker, Ford 9 inch with Detroit locker,
Front, is kind of a 3 point I guess; it has what looks like Ford tubular trailing arms, coil springs, Bilsteins, and a track bar but I do not see an upper control arm. Steering is a high steer/crossover setup with a Saginaw steering box.
Rear is a triangulated 4 point with brand new Bilsteins and a coil springs.
Wheel base is about 7" longer than stock CJ5. Almost new 35" A/T Tires, just had an alignment. I felt very little slop (but there was some) in the
steering box. None of the bushings or tie rods had slop that I could see.
What makes it sketchy?
1) The center of gravity is pretty high and there are no sway bars. Every change is momentum the whole truck moves. Give it gas and it wants to turn left a little. Let go of the gas and it wants to wander into the lane next to you.
2) steering is SUPER soft and it has a tiny steering wheel. When the truck does sway into another lane and you counter with some steering feedback, the body sways and wants to add more motion and it wants to over correct.
What have we done so far?
A) He wants to put a sway bar(s) on but there is no easy place to put it/them. We spent a good 30 mins trying to think of a place to mount the way bar and the end links. It could be done but he is not a fabricator and would prefer not dump $500 on having some mounts fabricated if it isn't really gonna make a big difference.
B) His front coil spring mounts bolt on to the frame and are adjustable. We tried lowering the front end as much as we mechanically could (was about 4" at the front winch) but then the crossover link (at the pitman arm) was only about 1.5" above the drag link and would have contacted anytime the suspension compressed more than 1.5". He could move the drag link under the knuckle to gain steering clearance but then he loses ground clearance. Again, he would be willing to do that if it would make a pretty drastic change in handling characteristics but neither of us was confident it would so we put it back.

So, any ideas that could help? Stiffer springs? Add a third mounting point to the front axle? Sway bars/Anti-rock? a bigger steering wheel?
