Ball joint nuts in front control arms

Background

Volvo Cars has decided that a defect related to motor vehicle safety exists in certain model year 2004 S60, V70 (01-) and S80 Volvo cars. The ball joint (SEMS) nut securing the front control arm to the spindle may lose its initial tension. This defect may cause the steering wheel to go out of alignment, potentially leading to front end suspension noise. Under certain driving conditions, the vehicle may become less responsive and the driver may experience steering wheel play. In rare cases, the control arm and spindle could separate. The corrective action will be to secure a modified ball joint (SEMS) nut to the spindle with increased torque.

Replacing the ball joint nut 1

Note!
Replace on both sides. Remove the front wheels.

Caution!
The ball joint pinion must not rotate. Use a Torx wrench as a counter hold so that the rubber boot is not damaged.

Remove the nut on the control arm.





Torque tightening 2

Install a new nut.

Caution!
The ball joint pinion must not rotate. Use special tool 951 2927 (torx 40 long version) as a counterhold to prevent damaging the rubber boot.

Tighten the joint. Tighten to 50 Nm. Using the torx 40 as the counterhold.
Then continue with angle-tightening. See step 3.





Installing the ball joint nut, angle-tightening 3

Angle-tighten 35°. Use angle gauge 951 2050.

Note!
A counterhold is not required when angle tightening if the joint has been tightened to 50 Nm. Because the friction between the ball joint and control arm is greater than between the ball joint nut and threads.

Install the wheels.
Tighten to 140 Nm.
