OK, so I know that CJ's stearing sucks. Is there anyway to make it so that the jeep feels good while driving over 55 MPH? Any aftermarket parts to do this? There isn't alot of slack in the stearing the jeep just has a mind of it's own once it hits the highway. Any suggestions are welcome.
No It's pretty much sucked since I bought it. Its an 86 CJ, with 33's. The damn thing is horrible on the highway. Id really like it to run good on the highway so I don't have to tow it to the deer lease everytime I go. I know the short wheel base isn't the most condusive to high-speed handling but it realy sux. Any input would be great.
What eight said is right, if you have lift shackles, it will mess up your camber. You have 2 options then, either grind off your spring perches and rotate your axle back and reweld them in place. You can also put shims between the spring and the perch. If you are going to do any serious off roading, I would go ahead and reweld the perches. The say that the cast shims can break and come out. I have never actually seen it happen, but it is possible.

This may sound crazy, but what pressure are you running in the 33's? If your contact patch is too small, the jeep reacts more to the heavier rotating mass of tires and tends to bounce off the small bumps in the road. This was the problem in my buddies CJ with 33s. He lowered the pressure (from 35 to 23 or so) and said it was a world of difference. Also check the wear in the box, tie rods and front bearings as these Jeeps aren't getting younger and have both milage and age against them. I'm running pretty much all stock and it tracks better with speed. Yes, I can take my hands off the wheel (even at higher speeds) and it tracks great. I'm stable up to 90mph or so.
you're running 33s? you have a lift? what kind of angle is the draglink compared to the tie rod? why is it only bothering you over 55? have you checked all your rod ends, ball joints, steering box, steering shaft, and steering column for any kind of play?

I know, it sounds strange, but I run 75 to 80mph all the time and it does it just fine. Running 265/70/R15 dunlop rover AT's at 25 psi in the front and 23 psi rear, with 3.31s , 5th gear and 258 engine (165 thousand miles).....I credit the tires matching the power band of the engine (I believe it's 2500rpm at 75mph). Hard top must be on as due to a low pressure drag, I can only do 70 (= OR -) with the top off.
Now I have a CJ-6 that you couldn't pay me to drive over 50mph in it! and its a longer wheelbase (104) It's just a whole different feeling creature. Not all CJ's are the same. Each one I drive has it's own "feel" .....some I trust, others I don't.
Have you thought about a shackle reverse? This is something I've thrown around, but I don't do highway much in my jeep anymore. I worked with a guy who had a shackle reverse and he said it was night and day in the way his jeep drove. Also, I thought my steering box was in good shape, but replaced it with an AGR superbox 2 when I got the engine built. It drives a whole lot better now (course for what the agr box/pump costs it ought to!) Just a couple of thoughts. I also have heard that your front u joints (in the axles, not on the driveshafts) will wear and cause sloppy steering. Another thing to look at. This is a problem common to a 20 year old jeep. If you want good steering you can replace u joints, ball joints, steering box, and tie rod ends, and it should drive great (at a pretty hefty price). It is possible for a jeep to drive well on the highway. The guy down the street had an 86 with 19K miles on it and it drove like a caddy (and he sold it for 5500 with HT/ doors and a warn 8274 on the front, no rust, paint like new, renegade package, don't get me started on missing that one). I personally would look at the shackle reverse first, they're about $200 (or you could try to make it yourself).
