I want to know what MM size are my front sway bar so I can buy the correct bushings for it.

 

I think its 24mm, but not 100% sure. Its not hard to measure, but the bushings are a pretty big job to replace. You can probably measure it if you just turn the wheels all the way and reach behind the tire.
You should do the lower control arm bushings at the same time. If you're worried about the sway bar bushings being worn, your control arm bushings are probably shot also. You have to drop the front subframe to get to them, including unbolting the rack. Its not hard work, just a decent amount of parts to remove.


Have fun,
Mike
