  Q: How to remove and refit the ball joint and control arm on Volvo V70?

  A:

  To remove the control arm, first loosen the appropriate front wheel bolts, chock the rear wheels, apply the handbrake, jack up the front of the vehicle, and support it on axle stands. Remove the roadwheel, then release the screws and take off the engine undershield. Next, undo the nut securing the balljoint shank to the control arm using a Torx bit to counterhold the nut, then lever the arm downwards over the end of the balljoint shank. If necessary, undo the two bolts and remove the balljoint from the base of the hub carrier; if it is difficult to remove, use a slide hammer attached to the balljoint shank. For the left-hand control arm, undo the two inner mounting bolts, withdraw them, and remove the arm from the vehicle, noting that new bolts will be required for refitting. For the right-hand control arm, raise the engine approximately 25 mm, pull the plastic cover on top of the engine straight up, undo the bolts securing the engine cross stay to the brackets on the suspension turrets, and position a workshop jack under the engine sump with a block of wood to protect the casing. Then, undo the bolts securing the right-hand engine mounting to the cylinder block and the bolts/nuts securing the front engine tie-rod and rear mounting pad to the subframe. Use the jack to raise the engine approximately 25 mm to access the control arm inner bolts, undo them, and maneuver the arm from the vehicle, noting that new bolts will be required. For the overhaul, clean the control arm and the area around the mountings, inspect for cracks, damage, or distortion, and check the inner pivot bushes for signs of swelling or deterioration. If either bush requires renewal, it should be entrusted to a Volvo dealer or specialist, as a hydraulic press and suitable spacers are needed for removal and refitting, along with a setting gauge for accurate positioning. For refitting, locate the arm in its mountings, fit the new mounting bolts and nuts, and tighten them to the specified torque. If the balljoint was removed, refit it to the hub carrier and tighten the new retaining bolts to the specified torque. Engage the balljoint shank in the control arm, tighten the new nut to the specified torque, followed by the specified angle, and complete the refitting as a reversal of the removal process.
