    FCAB Rubber Bushing Install

    I have always tried to install the Front Control Arm Bushings (lollipops) while the Front Control Arms are still on the car. I know you can pop the ball joints loose, which makes the bushings easier to install, but that seems like a lot of work.

    The hard part of this method is that the rubber bushings don't really want to on the ends of the arms very easily, even if they are lubed up good.

    I have, however, discovered a secret. I'm sure that someone else knows this secret, but I've never seen it. The secret is: don't try to push the bushings on straight. It will take you forever and you will swear a lot. Instead, twist the bushings on, as if they were threaded. They will go right on with only a little pushing.


    Does everyone else already know this, and I'm just behind?

    That's how I get them started, but I used to use a V shaped piece of all thread and a piece of bar as an on car too. With twisting I suspect you'd really need to be careful about lubricating the CA stub forward of the bushing lest it get stuck out of position, and it would be even better if you jam the CA down so you have more room to work.

    What lubricant did you use?

      I was a bad person and used wheel bearing grease. Not sure about all the warnings about using it because they still get really stuck on the arms.

        If it sticks, we must acquit, I suppose.

          If you use the right tool, the lollipop can be removed with the CA still on the car. If you have stock centered bushings, you should be ok for the most part. If using the offset m3 ones, will shift it.

            It was not cheap, but I bought the Bav Auto CAB tool when it was on sale. After two bushing replacements I LOVE IT! Makes the job quick and easy on the car.

              I have always just muscled them on, or hit them with a dead blow. Removal sometimes requires a 2 arm puller, or if they are broken, pull the lollipop off and slice the steel insert.

              As far as pressing the actual bushing in/out of the lollipop, an old bushing with a slice in it works great for pressing them in/out. Since there's a slice in the metal ring, they slide right through to press out the old, and stay neatly in the lollipop, then fall out when pressing the in new.

                When you press the bushing into the lollipop, do you use a press?

                  Press, or a bench vise, both work well, although my preference is the vise as it seems easier to get it started square. I've always used centered bushings, so getting offsets to stay clocked seems like it could be a bit tricky as even the non solid centered bushes seem to move a bit from their ideal orientation.

                    I do just because there's one set up at work. :p

                      When you are pressing bushings into/out of lollipops on a press, what do you set the lollipop on top of to keep it in place without interfering with the opening for the bushing?

                        Arbor plates in both cases, or a set of ball joint press cups if you have them.
