Question 1

How to check and replace the ball joint on Volvo 740?

Accepted Answer

Check the play on the ball joint at the axial and make sure that the axial play is not greater than 0.12 inch (3mm) and the radial play is no more than 0.02 inch (0.5mm). For the 240 Series, jack up and safely support the vehicle, mark the position of the wheel stud closest to the valve, remove the wheel and tire assembly and remove the ball joint nut from the knuckle. Remove the 4 bolts holding the ball joint and remove the ball joint from the control arm, then remove the ball joint retaining nut and squeeze the ball joint out. When installing, make sure that you use the correct ball joint for each side, press it into place, install it on the control arm and tighten the bolts to 44 ft. lbs. (60 Nm). Attach the ball joint to the knuckle and tighten to 85 ft. lbs. (115 Nm) then install the wheel and align with the previous marking and lower the vehicle. For 700, 900, S90 and V90 Series, repeat similar initial steps and then remove the anti-roll bar link bolt, cotter pin, nut and washer for ball joint stud. Use a suitable puller to separate the control arm from the ball joint, take off the bolts fastening the ball joint with the spring strut, and press the control arm downwards to separate the ball joint. Install the new ball joint using new bolts, applying sealing fluid to the threads, making sure that the bolt heads are flat, and tightening to 22 ft. lbs. (30 Nm) plus an additional 90 degrees. Reattach the control arm to the ball joint, secure with washer and nut, Tighten ball joint stud to 44 ft. lbs.(60 Nm), install cotter pin, reattach anti-roll bar, install wheel and lower vehicle. For 850, C70, S70 and V70 Series, lift and support the vehicle, remove the wheel and remove the three nuts securing the ball joint to the lower control arm. Remove the clamping bolt and nut from the steering knuckle and spread the ball joint apart and remove it from the hub housing. Clean the control arm and steering knuckle, install the new ball joint with the clamping bolt and the nut, tightening the same to 37 ft. lbs. (50 Nm). Connect the ball joint to the lower control arm, fixing it with new nuts, applying rustproofing compound, and tightening at 13 ft. lbs. (18 Nm) followed by an angle tighten of 120 degrees. Finally install the wheel and lower the vehicle.

Question 2

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

Accepted Answer

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.
