The ball joint in my rear upper control arm went out on side of road. I was wondering how to get the 3 bolts on top the cross bar of the arm off.
Do you

INSPECTION
Inspect the control arm for physical damage. If it is determined that the upper control arm is broken or bent, the upper control arm must be replaced. The rear suspension upper control arm is not a repairable component and no attempt is to be made to repair or to straighten it. The upper control arm must be replaced if found to be damaged in any way.
Inspect the control arm pivot bushings for deterioration. If found to need replacement, the upper control arm is to be replaced.
The rear control arm, control arm bushings, and pivot bar are serviced as a complete assembly on this vehicle. Do not attempt to disassemble the control arm from the pivot bar to service the rear control arm bushings.
The only component on the upper control arm that is serviceable is the rear upper ball joint and its seal.

ASSEMBLY - UPPER BALL JOINT
1. By hand, position ball joint assembly into ball joint bore of control arm. Be sure ball joint assembly is not cocked in the bore of the control arm, this will cause binding of the ball joint assembly, when being pressed into lower control arm.
