Bushings Upgrade For WRX
The trailing arm bushing is more difficult to remove. It has a flange that must be chiseled off, here Howard does so with an air chisel.
Once the flange was raised, Howard cuts it off with a cutoff wheel.
Now the bushing can be pressed out.
The stock bushing is soft rubber and has many cutouts that allow for a lot of movement. The Whiteline bushing is solid and made of a much harder material.  The trailing arm bushing is important to keep the rear geometry in line, especially under braking. Minimizing movement will help stability.
The trailing arm bushing has a steel shell and has to be pressed in. The sleeve is greased and inserted by hand.
We checked the lateral link bushings and found that after 10 years, they were still like new! We just re-greased them and put them back on.


  1. I have a lot of the same parts on my 2005 WRX and absolutely love them. One question, if you needed to replace the rack is there a reason you guys didn’t upgrade to the 2015+ rack? There’s a bit of fabrication needed to make it work on a GD but I’m really glad I did it.

    Keep the GD WRX updates coming, I’m really enjoying them.

  2. Hello MotoIQ. I’ve just wrapped up doing front lower control arm front, front ALK, rear lateral links, and lateral arm bushings from whiteline in my 1999 Subaru RS. I have already had the Roll Center Adjuster kit a few years now.

    I haven’t driven the car yet, but what is your take on these parts “binding”? There’s a lot of info about urethane binding on the net, but I figured Whiteline has taken this into account…or have they? Thanks in advance!

    1. Hi Mike,

      How often do these bushings need to be re-greased? Would it be helpful to wrap the bushing sleeves with teflon tape (doesn’t look like it was done in this instance)?
