    If I put both on one side with arrows to ball joints won't it cancel out some positive camber?? And defeat purpose of installation?? Just wanna make sure efore I dive in

    The instructions are not correct. I don't have the correct instructions handy, but they are out there.

      Both holes outward would give the most negative camber. Both inward would give you the most possible positive camber.

      Installing the front bushing with the hole farthest from the ball joint and the rear bushing closest to it it will shift the ball joint aft giving the most caster.

          An off set on both sides gives the maximum amount of adjustment because there both off set for more travel/adjustment. Not just one bushing.
          Go for it.

            I just went thru this again.... the instructions are not very clear and there seem to be contradicting advice.
            I went 1 in..1 out...
            Dont feel stupid

                FWIW, I installed them (per the above photo) when I fully rebuilt my suspension, asked the alignment shop to max out the caster and WOW...what an improvement.....tracks so much better on the highway now! "Almost" like a new car...I really need to send my steering box to FirmFeel.....

                  Also with the Ferrules/ washers, do I press one in before I install or do both after to not damage?

                  You cannot install them after. They go in as a set

                    Wait ..the inner washer is bigger than outer bushings sleeve..so would have to at least put that one in after

                    You press the bushings in and then squeeze one washer on each side of each bushing before you stick 'em im the frame receptacles.

                      The washers have a centering locator step over 1/16 high, that is a light press fit into the bushing. There is barely room in the frame saddles to receive the assembled LCA, and often you have to slam them home. There would be no way to put the washers in last, not even just one.

                      I have come across many bolt sets that do not have enough threads to properly compress the bushings. They are just long enough to fool the tech intosigning off on the job..... and the next day. or even on the roadtest, the the bushings slip, And he gets a do-over. We hate do-overs. The solution is thick hardened washers installed either on the nut side to push the nut further away from the shank, or under the head to suck the threads further away from the nuts. I just put two on each, one at each end, for a forever fix. But that was nearly two decades ago; they may have fixed that,IDK.
                      Just FWI

                      Ohhhhhh, yeah well then no washers at all!, you have to press on the outter sleeve with a corret size driver, while the arm has to be supported with a correct sized receiver...., else you will tweak the arm into uselessness

                      Well, I hope them pics about the Moog K-7103 offset bushings are right. I just removed the new ones I installed in a set of UCAs, and reinstalled them as per the pics in post # 7. I pressed in the supplied washers, with the large one on the outside of each arm.
                      I also installed new Lrg ball joints. one torqued down to 125 ft lbs, the other wont toque at all. Guess i have to brake out the welder, and tack it.
                      I have to say that a few years ago, I bought the Mopar front end tool kit from Mancini, and it works well. I also used the HF ball joint kit to help install the Bushings. Both tool sets are great to have.
