    I've been on a mission to fix some clunking in my front end. I have replaced my UCAs as the bushing began to fail around 40k miles, and just wrapped up a brake job. Unfortunately, I have found out in the process of replacing that the LCA bushings are bad.

    I ordered a set of Superpro LCA units. They are the double offset, TRC484 kit viewable here. As they come with the ball joints, bushings and the arm, I figured its the most hassle was to get ahead on regular maintenance.

    My question is if anyone here has any sort of firsthand installation knowledge, especially with the cam bolts. The Superpro LCA set comes with all new bolts, and apparently there are two types of LCA for non KDSS, a caster-adjustable only, and the double offset, caster and camber. If I follow the usual method of using a paint marker where my cams are to get alignment ballparked after the install, will this work on these replacements, since they may be slightly different from OEM? Any tips for my install? I plan to use anti-seize on these bolts as I live in the north.

    This is my first attempt at LCA work, but my UCA swap was my first endeavor into swapping something on the front end. Im confident in my ability to properly install everything, but I am most concerned about the alignment aspect. Any help would be appreciated!

    Put the cams in roughly the same spot and it’ll be fine until you get it aligned.

    There is no way to adjust exclusively camber or caster on an a-arm via the pivot bolts. Any adjustment is going to move the ball joint along an arc. The front should have more camber impact and the rear more caster due to asymmetry but putting a non-cam bolt in one doesn't mean it locks either value.

    Cam bolts should have little tick marks on them - you can use those to transfer over markings but if you've on bigger tires, standard procedure is cranking the rear all the way out and dialing in the front adjuster. If the 4-position bolts in the listing mean they have octagonal washers and not round, you can use them for this purpose. Any camber setting should be fine to get you to the alignment shop with a little care.
