I have the same whell shimmy problem when braking at high speeds like many others do here and now I'm trying to fix this problem. I have the stock wheels setup and I just aligned all wheels recently and that didn't fix the problem, so now I'm gonna try to replace the lower control arms.
I'm a little confused tho.....can someone tell me if I have to change the whole control assy. or is it just the bushings at the end?
There's a significant price difference.
here's the link I found on the DIY from Drex:
