Break loose the Ball Joint Stud
The ball joint stud is press fitted into the steering upright. In order to break it loose, use a
hammer and hit the steering upright near the stud. After a few hits the stud should pop loose.
The castle nut is the only thing keeping the rest of the suspension from springing down, so do
not remove the castle nut yet!
4
Detach the Ball Joint Stud Completely
Place a floor jack underneath the front lower control arm to support the spring load. Once the
load is off of the castle nut you can safely remove the nut and allow the ball joint stud to
detach from the steering upright.
5
Detach the Upper A-Arm Cross Shaft
The only thing left holding the a-arm in place is the cross shaft. There are 2 nuts that secure
the cross shaft to the subframe. Loosen and remove these nuts. You will also need to pop
the cross shaft bolts out in order to remove the a-arm completely.
