Changing a Broken Stabiliser Link
The function of stabiliser links, also known as connecting rods
They transmit torsional forces occurring between the body and the chassis to the stabiliser of the particular axle. Depending on the design of the front or rear axle, they form the necessary connection for optimal interplay between wheel guidance and stabiliser. The body roll of the vehicle during cornering is minimised, ensuring safe roadholding.
Defective stabiliser link?
The symptoms
While driving, the following signs may indicate a faulty stabiliser link:
- Rattling and thumping noises on rough roads
- Imprecise vehicle handling
- Stronger inclination of the vehicle during cornering
If the stabiliser link is found to be defective, it should be replaced as described below.
Note: The pictures used in this practical tip and the procedure described for changing the stabiliser link on a Mercedes Benz C220 (S204) are examples and may vary depending on the vehicle manufacturer and axle design.
How to change
a broken stabiliser link:
1. Raise vehicle and remove front wheels.
Tip: Always check both stabiliser links and replace them in pairs if necessary.
2. Spray fastening nuts of the stabiliser link with rust remover and let act for a few minutes.
3. Loosen the lower fastening nut of the stabiliser link at the stabiliser and remove.
Tip: If the ball stud also starts to turn, hold it with a suitable tool.
4. Press stabiliser link out of torsion bar.
5. Loosen the upper fastening nut of the stabiliser link at the suspension strut and remove it.
Tip: If the ball stud also starts to turn, hold it with a suitable tool.
6. Press stabiliser link at suspension strut out of bracket.
7. Insert new stabiliser link at suspension strut.
8. Tighten stabiliser link at suspension strut to the tightening torque specified by the vehicle manufacturer!
Tip: Secure the ball stud against twisting with a suitable tool!
9. Insert new stabiliser link at stabiliser.
10. Tighten stabiliser link at stabiliser to the tightening torque specified by the vehicle manufacturer!
Tip: Secure the ball stud against twisting with a suitable tool!
11. Remount the front wheels. Lower the vehicle and tighten the wheel studs to the tightening torque specified by the vehicle manufacturer.
Tip: Even if replacing the stabiliser link does not directly affect the chassis setting, we recommend checking the axle setting and adjusting if necessary after working on the suspension.
12. Conclude with a test drive.
