Anyone Ever Rebuilt Their Power Seats?

[ec437]

My driver's seat has a couple annoying problems. First, the right side of the back tilt adjustment mechanism doesn't work right, and breaks again right after I fix it. The other (more) annoying problem is that whenever I come to stop or slow down, the seat rocks forward ever so slightly, and then rocks back again when I accelerate. Only enough to drive me insane. How can I fix that? Has anyone here ever rebuilt their power seats?
