A defective control arm can manifest in the following ways

(1).Noise (squeaking, creaking, rumbling).

(2).Deteriorating driveability.

(3).Increasingly woolly and imprecise steering.

(4).Uneven tyre wear.

Tip:If the control arm is in working order, it is possible to only replace the defective bearings and joints. However, replacing bearings, control arm bushings and ball joints can be very complex and costly.

1.First lift the vehicle using a car lift, ideally a wheel-free four-post car lift. This makes it easier to correctly tighten the control arm fixing screws.

Note

Do not tighten the fixing screws and nuts in this step, otherwise the rubber mounts will twist when the suspension compresses. This would lead to undesired preloading on the mounts.

11.Now lower the vehicle until the suspension is compressed. Depending on vehicle type, load or unload the vehicle until the required height published in the specific installation instruction is reached. This is where a wheel-free four-post car lift is advantageous, as the underside of the vehicle can still be easily accessed once lowered.

12.Tighten the fixing screws with the torque stipulated by the vehicle manufacturer.

13.Lower the vehicle all the way.

14.Measure the chassis and adjust if necessary.

15.Check and, if necessary, adjust the headlight settings on vehicles with automatic headlight leveling where the leveling sensor is attached to the control arm.

16.To conclude, test-drive the vehicle.

Ball Joint

Ball joints may be grouped into two classifications, load carrying and non-load carrying. Ball joints may be manufactured with forged, stamped, cold-formed, or screw-machined housings. The coil spring is seated on the control arm to which the load-carrying ball joint is attached. For example, when the coil spring is mounted between the lower control arm and the chassis, the lower ball joint is a load-carrying joint. In a torsion bar suspension, the load-carrying ball joint is mounted on the control arm to which the torsion bar is attached. A load-carrying ball joint supports the vehicle weight.
