Here, Chris Eimer is installing the new arms after they were fabricated.
The lower control arm rod end bearing acts as a ball-joint. We drilled the tapered hole out of the knuckle to run a 3/4″ bolt through it. We used high misalignment spacers to get more articulation out of the rod end.
It was not quite as easy to get our upper control arm on the car. We have to connect the upper control arm a little differently than stock.
We ran a 5/8″ bolt all the way through the spindle and the spherical bearing. This replaces the ball joint stud which is held in through a groove cut in the spindle and a clamp bolt. Unfortunately, that surface on the underside of the spindle where the bolt mounts is cut at an angle relative to our nut, which prevents us from tightening the nut.
To fix this issue we took the spindle over to the mill to create a flat surface for our nut to seat on.
