To replace the early type
Ball Joint you start by raising the vehicle's front, supporting it under the jacking points, and removing the roadwheel. Loosen the cap nut with a peg wrench or special Volvo tool, support the track
Control Arm with a jack and detach the tie-rod ball joint from the steering arm with a ball joint splitter tool. Next, remove the stabilizer bar from the link rod and remove the cover from the center of the strut top mounting. Unscrew the brake pipe bracket bolt and undo the strut spindle top nut without removal (holding the flats of the spindle so that it does not rotate). Mark the position of the strut top mounting with regard to the inner wing turret, and then unscrew and remove the 3 strut upper mounting nuts. To do that, lower the jack under the track control arm while holding the strut in place to prevent putting a strain on the brake hoses. Fit clamps to the coil spring to compress it, then unscrew and remove the strut spindle top nut and the top mounting components, as well as the spring. Remove the cap nut and pull out the shock absorber from the strut tube. Loosen the ball joint retaining nut, using a 19.0 mm socket and long extension, hold the tube against rotation using grips. Release the ball joint stud from the tube with the help of a long drift. A new strut insert can be fitted by reversing the removal process and if re-using the original coil spring, keep the clamps until fitted to the strut. If a new coil spring is being installed, open the clamps from the old spring slowly then fit them to the new one. The lower ball joint can be renewed after unbolting it from the track control arm. For refitting follow the reverse order of removal, ensuring to coincide the marks at the turret and that all fixings are tightened to the specified torque to ensure camber angle is correct. For the type ball joint later, the operations are similar but some specific details should be followed to disconnect it from the base of the strut.
