To access the upper control arm there is required a tool to separate the balljoint from the
Steering Knuckle. The right upper control arm holds the engine compartment fuse and relay box so to gain access to it release the tabs that retain the fuse and relay box to the mounting brackets. As for the left upper control arm, the coolant expansion tank has to be moved aside. After that, it is necessary to take off the upper fasteners for positioning the
Shock Absorber thus it is possible to have access to the facteners of the control arm. Next, remove the upper control arm mounting nuts which are on either side of the shock tower at the front part of the car. Before removing the wheel, turn the wheel lug nuts to a lesser degree of tight, further elevate the front of the car and place it on jackstands under the frame rails. Where the brake hose and the brake line fitting can be seen, the ABS wheel speed sensor harness should be unbolted from the frame bracket. Unscrew the nut of the upper balljoint stud slightly but do not remove it (P125) then, there is need to use a balljoint removal tool together with steady hand to pull apart the balljoint from the steering knuckle with the nut still on the ballstud to avoid sudden detachment. Take care to rotate and fix the steering knuckle out of the way, and pull the shock absorber further out. Torque the control arm mounting flag bolts and take the upper arm off its frame brackets. For installation raise the lower control arm with a floor jack to normal ride height before tightening the upper control arm mounting nuts at the shock tower. Removal of the balljoint is done in the reverse manner to installation process which entails applying new balljoint stud nut and tightening all the bolts up to torqued values. Last, the wheel and the lug nuts are to be fitted, the car is then rested and the lug nuts are tightened to the right torque while the front end alignment is checked and adjusted if required.
