CJ-7 swaying all over

My '84 CJ is starting to scare the crap out of me on the highway. The front-end is tight, the axle bearings are tourqued to specs, the ball joints are good, the steering stabilizer is good, and the alignment is good. The steering box, pump, and shaft are original. I have 31x10.5's and a 2.5" lift in it. I'm basically constantly steering or counter-steering to keep it in the lines. Could it be the steering box?

Re: CJ-7 swaying all over

Shackles are a common cause of wandering. Do you have lift shackels? Are they loose?

Re: CJ-7 swaying all over

When you say the alignment is good, are you referring to the toe-in or did you have the full frontend alignment checked? What you've described is a classic symptom of insufficient caster. If you have longer shackles, they roll the axle down in the front and reduce the caster. You might try some degree shims to rotate the axle back and see what happens. Toe out can contribute to wandering, too.

Good Luck!

Re: CJ-7 swaying all over

It does sound like a caster problem to me as well. Did it just become noticeable after the lift or has it just occurred out of the blue?

Re: CJ-7 swaying all over

The shackles are stock, and the bushings look good (Came with the lift). I haven't done anything to the suspension on the Jeep, i bought it as is and put about 20k on it. It started swaying noticably over the summer. Almost feels like one of the rear tires are low on air.

Re: CJ-7 swaying all over

Check the steering box. They get worn in the middle and tend to wander. To check this, look at the front tires while in the jeep. Now slowly move the steering wheel back and forth and make a note of it's position when the tires start to move. If it moves more than 1/8" turn in each direction without moving the tires, it needs to be tightened. The center of the gears get worn out and pick up some slop, then you have to constantly correct to keep it straight down the road. My '78 Scout II does this, it's hard to drive, only does it going straight, but you get used to it after awhile (until you hit the brakes and it sends you all over the road again). Check these few items and get back to us, I know I'm curious as to what it could be.

Re: CJ-7 swaying all over

JEEPN-

How much and how do i tighten the gear box? I know it has some play, on the road i can swing the wheel back and forth some and it stays straight.
