I saw on the alta site a replacement for the front control arm bushing. Instead it is a fixed point mount with a bearing for movement. Has anyone used this? What it is supposed to do makes sense to me, but wanted to know if anyone has used them.

They have been around for some time. They have a problem of the set screws not holding and some people have tack welded them to stay. By far the most used replacement have been poly controll arm bushings and can be purchased pre pressed into the bushing holders. That is a big help for installation and IMHO is your best choice. While you have the front subframe lowered it is a good time to do poly front sway bar bushings at the same time.

Also second the vote for the prepressed bushings. Much easier to install. I have run the new FCAB and sway bar bushings for a year now with no problems. OEM FCABs wore out at 50,000 miles.
