Am I steering my Jeep?

Now this issue has been plaguing me for some time, I am just now gettin gto the point where I can address it. Driving down the road and all of the sudden my jeep tries to switch lanes. Never the same direction, always keeps me guessing. Very exciting stuff here. This will happen of rough or smooth surfaces alike. Any thoughts?

I've got a 3" lift and mine did that bad too. I put a dropped pitman arm, and that seemed to help some but not totally. I'm starting to wonder if it's the 31X10.5 tires on stock rims or bent axle! Front end seems pretty tight.

If you remounted the spring perches on the frame to mount the ch*vy springs OR relocated the spring pads on the axle for springover, my guess is the caster/camber (can't remember which it is) is way off and causing the truck to wander.

Drive it right to an alignment shop and have them do a 4 wheel alignment and check the caster/ camber too. I guarantee it's way off. If it's not that you must be running 7" wide rims with your 12.5 tires.

SOA on top of 6" springs?
That's a lot of lift for sure.
Or are we talking SOA front and 6" springs rear?

The rims match the tires. Last time i had the alignment shop look at it, they said that the @!#$^!&&% was off just a little bit. That meant that the top of the tires was pointed in just a little bit, front and rear. There are no adjustments for these settings.

No. The soa and 6" lift springs are in the front. The rear has rebuilt/ relocated shackle hangers, AAL, and blocks bring it up even with the front.

When you did your SOA, did you convert over to High-Steer?

I want to SEE the caster numbers. Not be told that ANYTHING is 'just a little bit off'.

Was that after all the mods to the spring hangers? I still say the caster is probably off some. Did you SOA your existing front axle pads or did you install a factory SOA axle? The tires pointing in at the tops will actually help the handling. It shouldn't really cause it to wander.

Wow. Lots of great ideas here. I appreciate all of the feed back. I installed a DP when I did the SOA. I used the original axle and just welded on new perches. The angle is right at 4%. I did not convert to high steer. When the alignment shop told me the problem, they did give me exact numbers. With no adjustment to be made........... those numbers have long since left my brain.

I don't think there is enough info to help you. How flat is the drag link? Pictures? It sounds like you have alot of lift

X2 spring over + 6" lift= very steep drag link. Spring over got what... 6" or so lift & even using a 4" dpa your already 2" higher than stock. Plus add on another six inches of lift and you suddenly have a pretty steep drag link. Any little dip in the road will now suddenly feel like your driving drunk. Time for high steer.

Its really not THAT much of a lift guys. He said CHEVY 6" springs, which are only like 3-4" lift on a jeep + the SOA. To me it sounds like it either has too much angle on the drag link or you have the pinion angle too high for the stock axle. If you steer all the way to either way does it look like the tires are pointing towards the ground at all? That can cause it to dart around like that.

This is how tall a FSJ sits with SOA + 6" Chevy springs and 38x12.50 tires

One thing that really helped me with my bump-steer was taking pictures of my set up from a few angles and posting it on here for the guys.

Also, get all the angle measurements done like on your pinion, etc.

Mine turned out to be a bent leaf, bad steering stabilizer and shocks an' it needed a drop pitman arm to solve mine. Fun eh? Could have been worse.

The guys here are awesome if you can show them what they're dealin' with. Good luck!

When i had a similar problem. After some "hard" wheeling my steering gear had come lose from the frame. Have sombody steer left to right slowly and look at your steering components (espically the steering gear). Having an extra set of eyes help too.

If thats not the case (and i have a feeling it might be). Then look into caster issues.
