Bump Steer/Anti Lift Kit Install Help

Recommended Posts

Hello,

I am getting springs, swaybars, links, and the above kits installed in my 07 legacy. What i am trying to avoid is having to get two alignments. Should i do the springs first, wait for them to settle, then get the rest done/aligned or should i do it all at once and only align it after the install. Any advice/experience would be much appreciated. Thanks.

ALK is not the same as bumpsteer/roll center kit. Those are two different things.

 

ALK is just the front lower control arm-rear bushing. You won't affect alignment much (if at all) if you mark things. However, the RCK/BS kit will completely change alignment. You MUST get the car realigned after that is installed.

 

I'd put everything in, and then drive around for a week and get it aligned. Let the shop know to please try to get everything as close to it was before hand, even though it'll be hard since you're replacing balljoints and tie rods with different length units.

 

If your concern is tire wear, a week won't make or break you, unless you're driving a LOT. Get some fat friends to ride around your car. ;)

Jamal, you think so? I'm under the impression that if nothing else is touched, the ALK shouldn't change much in the way of alignment, provided everything else is put back the way it was, unless you get the offset bushings which will throw your caster off.

Actually, there is no caster adjustment on the subies. The lca bushings even the offset ones, only effect caster, so there is really no alignment needed if thats all one does.

 

With the springs and roll center you will need an alignment, so do em all and then wait a week to get an alignment.

Yeah, there's no caster adjustment on the car itself, but the offset on the bushing still has to be rotated/positioned properly. I guess you could eyeball it when installing, but I found we were off a bit when I went to get it aligned afterwards.

Gotcha. Yeah, an alignment always is a good idea, especially since we just got an alignment machine :)

they do change the anti-geometry (some by more than others), and by changing the caster you are changing the alignment of the upright to the steering rack, which results in noticeable toe out. When I install them I give the tie rods about a half turn in on each side before I even check the alignment.

Yeah I can see how that can change the tie rod ends to an extent, although we haven't really seen it effect it too drastically. Of course now we have a full alignment setup so we will be able to check them more precisely going forward. :)

my mechanic appears to have no faith in his abilities so he will be doing the springs first then i will be returning to have the suspension bits installed and have an alignment. Oh well the process will now be longer than it needs to be but as long as it gets done properly i suppose.
