Zrsnopro97 That's what I'm thinking also, got to be be a worn bushing or steering component somewhere...just have to find it. Thanks for the replies guys!

Oktavius There are three ways of adjusting caster. Ball joints, adjustable control arms, and a welder (rotating the C's on the axle tube).

Based on your caster value, I would look at other things before caster.

Zrsnopro97 Is the only way to adjust caster either offset balljoints or adjustable control arms or is there another way?

I’d be surprised if my caster being out of spec by one degree or so would cause this much of an issue. I could be wrong though. I might look at the tierods as soon as I get a chance to see if I see anything.

Caster can have a yuge affect on wandering but your values aren't crazy. My WJ is at 0.5 degrees at the moment as I was trying to reduce a front end vibration and 0.5 degrees caster resulting in a perfect pinion angle. At 0.5 degrees, the WJ does want to wander alot. For my WJ, it seems that having more than 3.5 degrees of caster is what I would consider acceptable for handling.

Think I narrowed down my vibration to lateral play with the transfer case's front yoke. Swapped the transfer case last night and ordering a new rear driveshaft. Will then increase caster angle until I get vibrations from the front driveshaft and then back it off slightly.

Skerrvydog Steering My 02 with ~125k was like walking a drunk to bed. Changed all 4 TREs and got it aligned and now itís smooth and tight.

jserna First what helped mine a ton was installing a ball joint spacer on the rear a-arm. I used one from Kevins off road.

jansel620 Yeah make sure itís off the jacks and on the ground. Have someone move the steering wheel back and forth. If the tie rod ends are bad you will see play in them. Same for the track bar bushings.

My 2004 WJ with 4.0 wanders all over the road at highway speeds, you can actually feel it as slow as 35mph but its worse the faster you go. My jeep only has 120,000 miles on it so its not completely ragged out. The issue is hard to describe but i find myself constantly correcting (turning left and right) to keep the jeep going straight down the highway. My family used to have a WJ years ago and I dont remember it doing anything like this. I've already dumped way too much time and money into this thing to give up on it so and i drive the highway every day to work so its real annoying.

This is what I have tried so far:

-Redhead Steering Gear box brand new
-2" Budget boost, new spring isolators all the way around.
-Bilstein 5100 series shocks all around
-All new upper & lower ball joints both sides
-All new rear upper and lower control arms.
-All new upper and lower front control arms. (did not change the bushings on the front axle yet that the control arm bolts to)
-Brand new 17" aluminum rubicon wheels and brand new Goodyear Wrangler TrailRunner AT's in 265/70/17 balanced
-Alignment at Belle Tire was done before the front control arms and steering box. They said it was close but there was play in my steering box which is why i bought the Redhead Box. Caster was the only thing that was slightly off. I have the alignment numbers i will post when i get home from work.
-Addco 1" rear sway bar with Iron Rock Offroad extended sway bar links.

Any ideas??? I have crawled under the jeep with the front end off the ground and attempted to check steering components and bushings with pry bar but not seeing anything too obvious.

Thanks.
My first thought, while reading your post, was, your rear lower LCAs. When they are bad, you WILL get "rear steer". You replaced those, so I immediately thought "front CAs".

I'm in the same boat as you. I have a 3" lift and have replaced ALL ball joints, TREs, track bar, steering sleeve and drag link, rear upper and lower CAs, as well as the rear upper A-Arm ball joint. The last two axle connections that aren't new on my 2002 WJ are the upper CA axle bushings. I have them, but haven't put them in yet. My front axle searches a little because of it. I'm anxiously awaiting my next layoff and have the tools to make a press kit now that I got a box of 3/4" drive BIG sockets and ratchets for $40.00 at a yard sale last weekend.

I tried using the press kit from AA to remove the two axle bushings, but it had too many moving parts and I had no help and couldn't get the things to cooperate. I YTed some videos and will make a bushing removal/installation tool for future use. I figure it'll knock HOURS of frustration out of a simple looking job.

Zrsnopro97 Thanks for the replies everyone! I will look at that TSB about the ball joints, however that would suck to have to do those again.

I have replaced the rear upper control arm which came with a new ball joint. That replacement actually fixed a separate issue I was having with an on/off throttle wiggle.

I have not replaced any tie rod ends or track bar or drag link yet... is there a way to visually tell if a tie rod end is bad? I guess I need to enlist a helper to steer the wheel back and forth while it’s on the ground and I’m under it. I tried it while up on jack stands and I don’t think there’s enough pressure/weight on the steering components to see anything then.

jansel620 I just dealt with this myself on my 2004 WJ. My problem ended up being the tie rod end at the pitman arm and at the steering arm. (Inspect them all while someone moves the steering wheel back and forth) But the biggest offender was that the track bar bushings were worn out. I previously pressed out the stock bushings and replaced them with the moog replacement bushings (bad idea), worthless and wore out fast allowing the front axle to drift back and forth just enough to cause the wandering effect at higher speeds. I opted to replace the whole track bar and it tightened up everything, no more wandering on the expressway.

If youíve lifted it, you may want to look into a quality adjustable track bar.

GmanWJ Two things: 1) did you change the rear upper ball joint? It mounts on top of the rear axle, connects to rear upper control arm. 2) did you change out the tie rod ends? There are 4 total.
Of these two the ball joint is often found to be the biggest contributor to wandering issues, but new tie rod ends really tighten up the front and make it less susceptible to bump steering.

Mofugly13 There is a TSB that addresses this exact issue I believe. Go to wjjeeps.com and search the TSBs. Seems like the fix is to install offset ball joints to adjust the caster.

Look for TSB. 0200102
