Alignment sheet after Mojave AEV lift help

[sandifer]

Could the shop had adjusted the control arms to whatever the manufacturer control arm lift/length grid stated without accounting for the changes with the GEO bracket? Like here's what I want installed and they just threw it on by the directions not accounting for the changes being made? Upload some photos of what your working with.

Thanks .... I'm planning on taking some pictures and do measurements tomorrow and uploading them. ...maybe that will help get to the bottom of this issue... thanks for your help..

Wasn't knocking the spacer lift. I don't think he needed to buy control arms and probably didn't need an adjustable rear track bar with the rear track bar bracket on 2". That is all. His money his Jeep, I got no beef with what he does with either.

Measure the bolt-to-bolt length of your control arms while you’re under there. The stock front lowers are 24”. Measuring yours will tell us which direction they went when installing.

The adjustable LCA's measure between 23 3/4 and 23 7/8. Hard to tell exactly looking at it without my glasses. Neither side was quite 24".

It’s

It’s where your upper control arms bolt into the frame/drop bracket. The installer or alignment tech may have rotated them incorrectly, or your control arms (if adjustable) may be measured wrong. Which arms are you running?

I hope this picture is the right spot. The square nut looks the same on both sides. The arms are Core4x4 and the bracket is AEV.

Interesting that off-center square is in a position to move the upper arm clear forward. That takes caster away (moves it in the negative direction)
So they had two ways to make caster in spec - move that square to move the upper arms back just a little, or adjust the lower arms to extend them a bit.
Those blocks should be in the same position on both sides so if they are the same, that is correct.
That block does the same thing as the eccentric on lower control arms of older cars, except for them it was setting camber, not caster -

Your lower arms are too short, and it looks to me like the square washers are installed the wrong way, pushing the upper control arms forward, decreasing caster.

Yup - those blocks should be flipped on both sides to pull the upper arm back.

 

[Renegade]

I also don’t like what they’ve done with your brake line brackets. They bent them to decrease your extension, and zip tied the bracket to the bar.

If the lift was installed per the instructions, the lower control arms would be set at 24”, and the washers oriented as specified below. Note the square and rounded corner notches.

LOL they got BOTH wrong - lower too short and upper pushed forward.
I was guessing that the uppers should be set to "medium" and that's what you are showing. Not clear forward, not clear back, one of the two middle choices.
I'd say they messed up - and good find on the tie strap on the lower arm. Ugh.

Man... Thanks for all the excellent information ShadowsPapa and Renegade...All of that is way above my pay grade. Looks like I'll be visiting a local 4WD shop ASAP...I got the feeling something wasn't quite right after seeing the ALignment sheet and I also fee the steering has a lot more "slack" than it did before.....Thanks again guys !!!!

so in reality are the rear LCAs necesary? I have a 2 in lift and noticed the other day my rear springs seems to bow towards the rear a little, making me think the rear LCAs are short now (theyre oem) I really just want to unass the rear geometry.

Those brackets would probably do the job but every where I look says theyre for the front?

They are only available for the front. A rear spring bowing to the rear might indicate a pinion angle which is high, but that pinion angle might also be necessary to maintain the driveshaft in a proper working range. There are spring correction pads available to compensate for spring bow, although I cannot attest to how well they work.

yea the pinion angle is off, im assuming, post lift. I did the LCAs for the front to correct it there. Thinking I may do the same for the rear. Ive looked under stock JTMTs and the springs are straight.

they had 3 possible options per the instructions and they somehow choose option 4... I bet I check these stupid washers 10 times before I put my tools away! some stuff is just to funny
