    just make sure that I am right, if the UCA is bad it can pull to that side & the camber would be off right?


    I had my alignment checked and it is pulling to the right & the camber is off. So I am thinking that mine is on the way or pretty much toast.

    It got moved from the Tech Staging area anyways so it doesn't matter

    I don't have any pulling, I'm not sure on camber issues, but the Jeep seems to be driving just fine. The only reason I was inspecting and ended up at ball joints was that I had a popping sound over bumps sometimes, so I jacked it up and started moving things around to see what the problem was..

    When the control arm is "bad", that either means the control arm bushings are bad or the balljoint is bad. These conditions result in popping/knocking noises; and bad control arm bushings can sometimes result in pulling while braking.

    Your camber being out is more of an issue of the limited adjustability of the camber/caster on these vehicles and running a 2+ inch spacer lift. First things first, make sure the tech actually adjusted the LCA. Sadly, i've seen many cases where shops just don't bother adjusting them on these vehicles (either by negligence or laziness).

    Well I got them installed.. I didn't do much with write up or pics. Reason being I was pissed at how long it took me.

    Here is why..

    The bolts to remove the UCA's were blocked by the springs. So I had to basically remove the struts.. which also meant disconnecting to sway bar to get everything to line up without fighting it too much. Overall the instructions are good, but depending on what lift you have or what position your springs are in, or how the moon and sun is aligned may change the difficulty. I'd give it a 3 out of 5 difficulty. If you aren't comfortable installing a budget boost lift kit, I wouldn't attempt this just because of the issues that I ran into, not huge to overcome, but might be more than some would be willing/able to overcome without help.

    Additionally since I had to loosen the struts, I ended up tearing on the of boots on my passanger side CV.. awesome.. so another job grew out of this one, thats no ones fault but mine, but just another reason to put it at at least a 3 wrench difficulty.
