Can the ball joint be purchased separately from the control arm, and How to remove and refit it on Volvo S40?

The balljoint is not available separately to the control arm but, if defective, the control arm/balljoint assembly will need renewing. To start removal, slacken the driveshaft retaining bolt, loosen the wheel nuts and then raise and support the front of the car and remove the roadwheel and engine undershield. Next, remove the driveshaft retaining bolt and discard it (a new one will be required during reassembly). Loosen the nut until it is level with the end of the balljoint shank and use a balljoint separator tool to remove the suspension control arm balljoint from the hub carrier by using an Allen key in the end of the balljoint shank to prevent rotation while loosening the nut. Use a stout bar to lever the control arm downwards and over the end of the balljoint shank, taking care not to damage the balljoint dust cover. Undo the two bolts holding the control arm back mounting and the one bolt holding the front mounting and work the control arm from underneath the car, removing the bolts as new ones will be required. For overhaul, thoroughly clean the control arm and the area around the mountings and inspect the arm for cracks, damage or distortion and carefully check the inner pivot bushes for swelling, cracks or deterioration of the rubber. If both bushes need renewal, it is recommended to seek the help of a Volvo dealer or specialist as a hydraulic press and appropriate spacers are necessary for removing and refitting the bushes along with a setting gauge to measure the correct positioning of the bushes. For refitting, locate the arm in its mountings, and fit the new mounting bolts, tightening them to the specified torque. Engage the balljoint shank in the control arm, and tighten the new nut to the specified torque, the rest of the refitting process being a reversal of the removal steps.

Volvo S40 Control Arm

The Volvo S40 Control Arm connects the frame of the car with both front wheels, allowing the suspension to roll over bumps with smooth movement; the whole car is maintained in position and therefore the steering is always accurate and contact with the tires is even. The Control Arm serves as the primary mounting point for shocks, springs, and the sway bar and attaches to the chassis by way of rubber bushings and to the knuckle by ball joints, allowing the wheel not only to go up and down but also to avoid sliding back and forth. Early Volvo models applied stamped steel arms, which are strong but heavy and prone to corrosion, an issue that would reduce the strength of the piece or trap the bushings, whereas subsequent Volvo models applied cast iron and lighter cast aluminum arms, which are resistant to rusting and shed weight to enhance the responsiveness of the ride. The second-generation S40, in front MacPherson strut use, places the arm at right angles to the car with an additional radius rod taking care of fore-aft forces, so it does not need to perform this duty in addition to the anti-roll bar and therefore moves more smoothly. The arm itself tends to be good over thousands of miles, but its bushings and a ball joint may wear out, and any collision with a curb that bends the metal or rusts deeply on a steel one demands replacement in order to keep the Volvo on track. Selecting a cast aluminum Control Arm will not only reduce the unsprung mass but also resist rust, which will keep the suspension sharp and reliable.

OEM parts are the only choice for top quality and real functionality. They pass strict checks, and they match Volvo's factory specs, so installation is easy.

Volvo S40 Control Arm Parts and Q&A

Lower Control Arm, Driver Side

Q: Can the ball joint be purchased separately from the control arm, and How to remove and refit it on Volvo S40?
A:
The balljoint is not available separately to the control arm but, if defective, the control arm/balljoint assembly will need renewing. To start removal, slacken the driveshaft retaining bolt, loosen the wheel nuts and then raise and support the front of the car and remove the roadwheel and engine undershield. Next, remove the driveshaft retaining bolt and discard it (a new one will be required during reassembly). Loosen the nut until it is level with the end of the balljoint shank and use a balljoint separator tool to remove the suspension control arm balljoint from the hub carrier by using an Allen key in the end of the balljoint shank to prevent rotation while loosening the nut. Use a stout bar to lever the control arm downwards and over the end of the balljoint shank, taking care not to damage the balljoint dust cover. Undo the two bolts holding the control arm back mounting and the one bolt holding the front mounting and work the control arm from underneath the car, removing the bolts as new ones will be required. For overhaul, thoroughly clean the control arm and the area around the mountings and inspect the arm for cracks, damage or distortion and carefully check the inner pivot bushes for swelling, cracks or deterioration of the rubber. If both bushes need renewal, it is recommended to seek the help of a Volvo dealer or specialist as a hydraulic press and appropriate spacers are necessary for removing and refitting the bushes along with a setting gauge to measure the correct positioning of the bushes. For refitting, locate the arm in its mountings, and fit the new mounting bolts, tightening them to the specified torque. Engage the balljoint shank in the control arm, and tighten the new nut to the specified torque, the rest of the refitting process being a reversal of the removal steps.
