My 2006 SC430 has about 130K miles on her and is in need of some TLC. I have already replaced a lot of the rear suspension with this kit from Figs (http://www.shopfigs.com/v3/by-vehicl...GAKIT_TRAC_TOE) with the MOTO-2-P option as this is for a daily driver. I have been very happy with this setup. I'll be putting this kit (http://www.shopfigs.com/v3/by-vehicl...GS-RUCA-HIGHHP) on at the same time I update the front-end

Fast forward to today and I am in need of refreshing the front end. I see figs has a kit for that (http://www.shopfigs.com/v3/by-vehicl...430-FR-REFRESH). I was going to get this, but was also wondering if I needed to replace the caster arm or bushing. In doing research on this site and asking Figs, all I have done is confuse myself. Is the caster arm the same thing as the lower control arm? Is this kit all I need? Are there more things I should consider outside of this kit?

Thanks for the help.

 

Caster arm is also known as lower control arm--LCA-- #2. In Lexulese is the lower suspension arm --LSA-- #2.

 

Okay, so by ordering the front-end refresh kit and getting the option lower control arms, I am replacing the caster arm/bushing. Thanks!

Next question, when I order the new lower control arms, do I spring for the poly bushings as well ($155 dollar add-on) or stick with what comes installed in the Mevotech arms?

 

Why order new caster arms? Why not just get the figs bushings pressed into your existing arms.

 

I installed the Generation 2 Castor Arm # 2 some time ago. I just ordered "front upper inner kit", SPF3161K, and "LWR ctrl arm bush kit", SPF4186XK. I ordered them believing these were bushings for the lower control arm and for the upper control arm. The Castor Arm bushing is shown as a seperate item on the master bushing kit list. The form lets you opt in and out for bushings you already have. Based on this, I don't think the castor arm bushings are the same as the lower control arm bushing. Am I missing something?

 

This answers it.
