Beside a bent axel,what could cause camber to be off?

Bad ball joints or unit bearings... check for play as they'll lean in with weight on them.



Zimm... yeah probably not a perfect balance. Try switching them around until you find some decently balanced tires up front, if not go somewhere else that can zero them out.

I can go to my alignment appointment Weds. and have a clue as to what they are taliking about, Thanks

Did you know they now have offset upper balljoints to set camber for the Jeeps? They have to replace perfectly good condition parts with new parts to dial in the specification then the ball joint is pressed in the adjust camber. Oh yeah its a one time shot and the ball joint can not be reused. A rookie can cost you a couple of bucks.

Can anybody help me with this. Had my 2004 Jeep Wrangler aligned and they set the front ok but they said the back axle was way off . This is a stock 04 that has not been in a wreak and has been well taking care of. I am not com. savy so I don't know to send alignment sheet but the readings are 0.80* left rear and-0.25* right rear with a 0.5* thrust . Now what can cause that and what can I do to fix

something is bent. look for bent control arms, the axle being off-center, bent track bar mount or bent track bar.

Found the problem where the lower right control arm mounts to frame the bracket is welded half a inch forward compared to left side . I guess its always been like this and I never notice it untill I put a 2'' lift and had it aligned

i have pmd flatfender couple times about my issues which im slowly getting worked out.first id like to say thanks to him and mud for this thread .i set my pinion angle and now my front axle is rotated to far foward i need to set my caster i will post my setup will you guys give me control arm lenghts? i have changed so many times their sure to be off.what caster number i should start off with? its grabbing cracks in the road pulling to the left and down right almost scarey on the highway.wheres the best place to set my angle finder to measure caster/camber? my front right tire is or was not sure now wearing bad on the inside.camber from last alignment before i set my pinion angle was -0.19 left -1.78 on the right(a friends shop did this i was standing there)but im still thinking about paying for a 2nd alignment.he swears i need an adj ball joint several other what i consider knowledgable friends say try and stay away from it this is getting expensive i need another tire now! heres my setup let me know if you need anymore info and thanks again guys sorry if any of this has been covered im a busy guy took me 3 sittings to read this thread i may have forgotten something

The first thing I would do, if this my problem, is to call the manufacture of the lift and ask for the arm specs. New in box length and the max/min length for adjustment. Then adjust them to original install length. Then get a alignment at Les Schwab, they have a 30 day warranty on alignments and they will re-adjust the settings for free if your un-happy with the handling.
I had Teraflex Longarms and they set my original caster setting at 00.00, then I added 3.98 caster to my jeep and it handles perfectly.

[jeep2008]

These are my numbers,what do you think?

caster:left+05.18 right+05.37

toe-in:total +1.2mm/left +0.6mm and right +0.5mm

camber:left-0.81 right -1.13

a rear thrust angle of .5* will make all the other #'s look way off, if you correct the thrust angle with adjustable CA's or fix what ever is bent, the specs will likely be where they belong..

assuming you have a RE 4.5" and adjustable arms, you're stuck with the uppers @ 15.5", which is as short as they go... set the lowers @16.5", make sure you have at least 3" bumpstop extensions to keep the JKS JJ end from hitting the differential. the 16.5" length will help keep the 37's off the fender well at the firewall.

I'd install .5* ball joints to correct the camber. spec is -.3 so a 1* offset ball joint will be a bit much...

Okay guys, lemme' start with what a great write up! Thanks to all involved!
Now I have a question, I purchased a used 4" Rough Country lift for my LJ. I installed the lift, along with adjustable front and rear upper control arms, from Rubicon Express. I also installed a heavy duty drag link/tie rod set from Rugged Ridge. I'm running 35's on 16" wheels. I got rid of my death wobble by lengthening the front upper control arms 1". (I think I have a 5.5 degree caster angle now)
There are some vibrations i feel comming from the rear, and I would like an alignment done. The shops that I've called in my area have all said the same thing, I need to find the proper alignment specs...
What would the alignment specs be for an 06 LJ with 4" lift sporting 35" tires on 16" wheels?
Any help would be appreciated, Thanks in advance.

[flatlander757]

Stock toe and camber specs

Set caster to 5 degrees.

Thank You Flatlander!

Sorry to but in but I need some help!

1999 TJ 4.0L RE 3.5 in SA lift with Fixed lowers and OEM upper on front, adjustable rear uppers and fixed lowers on the back. In the past I have aligned it myself with the old two rods and tape measure trick and never had any issues.

Anyway I let my Swampers wear out way beyond the point to replace. They were so bad I had bad vibration from them. Well I just replaced them with Mickey Thompson MTZ 35x12.5/15 and replaced the worn-out steering stabilizer too. I grabbed the tape measure to make sure the alignment was true and it needed a tad bit of adjustment. I assume this was due to going from a 34 to a 35. Well I drove it a bit and had some shimming at high speed say 50+ MPH. So I crawled back under it and measured again made a small tweak and figured that would do. Well I still have the shimmy at 50+. So I decided to have a local shop give it the once over since I guess I was doing something wrong.

Well they got:

LF -0.5 RF -0.9 Camber
LF 5.4 RF 5.3 Castor
LF .12 -0.09 Toe
Total Toe 0.03
Steer Ahead .11
LR -0.5 RR -0.8 Camber
LR 0.04 RR 0.22 Toe
Total Toe 0.26
Thrust Angle -0.09

Before they made any adjustments. Now it’s at:

LF-0.5 RF -0.9 Camber
LF 5.4 RF 5.3 Caster
LF .16 RF .11 toe
Total Toe .27
Steer Ahead 0.03
LR -0.5 RR -0.7 Camber
LR 0.05 RR 0.20 Toe
Total Toe 0.25
Thrust Angle -0.08

Anyway Discount tire mounted the 5 wheels and balanced them and I had them check for any wheel damage. The tech there I have used several times and he’s top notch he said he zeroed out the tires on the balance.

I have crawled up under and checked everything twice and nothing appears loose and when I put a wrench on it, it seems good and to torque.

I have put maybe 100 miles on the tires since install and can’t seem to shake the shimmy.

Any idea’s am I just overlooking something. It feels like a very mild death wobble and seems to stay with the speed until I get up to like 65+ or more.

Thanks for any help.
