Lifted cj5 questions

Hey guys, I am trying to get my jeep going safely down the road and have a few questions. The jeep likes to wander some driving down a straight flat road and to be honest I only want to take it to around 45-50 mph tops as it seems it's too risky anything above that. The jeep is stock steering wise. Has 33x12.50 tires. My dad put a lift on it years ago. He says it has about a 3-4" lift. He told me he re-arched the springs(I don't know how much) and he put bigger shackles on it and I think they are 4 inches as they are 4 inches from center bolt to center bolt. I am planning on replacing all the old rubber bushings with new poly ones(they are deteriorating pretty bad) and taking it to get aligned. I figure that might help some. Something I read in the forums was that a lot of times when cj's are lifted the tie rod Or the pitman arm angle might be a bit off??? So I took a few pics of my front suspension to show you guys and see if you think it definitely needs some adjustment or not. I checked The steering shaft and it moves maybe a 16th of an inch when I try to pull it back and forth. The steering seems to have a little play but not much. I've read you can tighten up the steering box somehow but I figured I'd get the suspension tuned up first. Something that crossed my mind since I was gonna put new bushings in was maybe I should get some Stock sized shackles and put them back in if that would help with handling??

The wandering may be a combo of things, but most likely it's due to too little caster angle, caused by the longer shackles.

Ideally, the tie rod and drag-link should be parallel to each other. A drop pitman arm and/or a tie rod flip would help yours. That said, improper tie rod/drag-link angle causes bump steer, not wandering.

You should read this.

You're on the right path. Replacing those worn bushings and getting it aligned should make a big difference. Those shackles don't look bad, nor do your angles. The alignment shop can also telll you if you need to add caster shims and what degree.

Thanks guys, I definitely want to get this thing in good running/handling shape. I would love to drive it everyday if I wanted too after I finish it up. Only problem now is the money for parts as it needs new tires, a top, plus the suspension tuning costs

How much pressure are you running in the tire? Too much and mine wanders. If you are running the max pressure in them try letting 5lbs out, or even a little more.

I agree your angles are not too bad. Looks almost the same as mine, which i fine handles great. I have same length shackles also. I would check steering box bracket for play. Cracks can be hard to see.
