    These are pics from the alignment printout from doing a suspension lift on my 2011 Tacoma DCLB 4x4 Sport. First 2 are before and after the night I stayed late at work and did the whole rear and front lift by myself w an alignment w/o new upper control arms. The next 2 are from today with a before and after from adding my new Light Racing UCA's.

    This is the order of the pics:

    1) Right after lift install no adj.

    2) Close as possible to stock maxing out factory adj.

    3) Right after UCA install w/ old adj still.

    4) Current alignment w/ new UCA's (will probably re-check again in a few weeks)


    These are also my heights going from bottom of fender to center of hub with the truck on the ground.

    LF = 23
    RF = 23
    FR = 24
    RR = 24

    Currently the truck drives great, no more wondering unloaded. Also before the LR UCA's post lift from lock-to-lock I got rubbing when at max left and right while moving. After LR UCA's all better.

    A tip for the long bolt, I bent back a little bit of the inner fender but still wasn't enough. Took my 90* grinder with a ceramic nylok disc and sanded down one side of the washer flat to one of the "hex" sides of the "bolt head."
    Doing so let the bolt side out as long as the flat side I made was facing the fender.

    Only issue is a vibe at 65mph. Had before lift also, still there. Felt through steering wheel. Tires balanced perfect with 6 finger thing, still there. Currently using "counteract balancing beads" in all 4 tires, still there. Don't remember if it did it with the factory Grantreks. Could it be b/c of the agressivenes of the Dura Tracs? Or could it be my 2 piece driveshaft angles are not correct?

    I went back and looked at the caster before I did the alignment the first time post lift. Went with the 2* DEFAULT SETTING on the LR UCA's b/c I maxed out the cam adj before. That's why in pic 3 my caster is over 3*. This would let be back them off to get the alignment in. After the cam adj with the factory adj, I then fine tuned camber. Factory is .5* positive, I went with 0.0* camber.

    Thanks OP. so you did not use the adjustable ball joint for the fine tuning of the camber? and used the trucks ability and brought your lower cams back in from max?
    mine now is maxed out on the lower cams and was able to get .2 and .1 camber but sacrificed the caster. What i want to do is put these UCA on an bring the factory settings back from the max and have them more in there middle range.
    I have the instructons for the arms and understand the caster deal and the "D" setting for the 2* as you did , but the camber bit about sliding the ball joint back and forth in the slot i'm not that familiar with. Is there a middle setting for it as well and then the tech can bring my factory cams back from the edge ?
    Cheers:)

    I got a great alignment with my LR UCAs as well. These things are great aren't they? I got 2.5 caster on both sides, 0 camber, and 0.01 toe on both sides. Drives great! I assume I will have to have it checked again in a while as well.

    For the "camber adj" on the LR UCA's there is no middle adj stop it's sloted the whole way. The person doing the alignment will need skill and finesse to get it perfect.

    After I pulled the caster and some of the camber w/ the new UCA's on, I then fine tuned the camber. With the factory cam adj they are in sync with caster to get .5* camber at perfect factory specs. If you want 0.0* camber you then adj camber ONLY with the top balljoint adj.

    Here is the order in which to do each alignment angle adj and wear angle FOR TOYOTA TACOMA W/ ADJ UCA's

    1) Pass side lower cam adj, switch between front and rear cams
    2) Drivers side lower cam adj, switch between front and rear cams
    3) Fine tune CAMBER only with the top balljoint adj
    NOTE: I found it easier to do this using the "jack compensation" feature on our Hunter alignment rack. Lets you do this with the front suspension unloaded.
    4) With truck still in Neutral start up and then center steering wheel
    5) Toe adj on the pass side
    6) Toe adj on the drivers side
