Light chassis knocking on uneven roads: anti-roll bar link ball joint play check
Light clicking or knocking occurs while driving straight over uneven roads.
Light chassis knocking on uneven roads: anti-roll bar link ball joint play check
Symptoms
- Light clicking or knocking occurs while driving straight over uneven roads. [1]
Possible causes
- Anti-roll bar link ball joint wear, or water ingress and corrosion after dust boot failure, can cause excessive play and abnormal noise. [1]
Checks
- Have a qualified technician check link play with the wheels on both sides raised, and check ball joint and anti-roll bar bushing wear at the same time. [1]
What to do
- Replace the link after confirming excessive play; compare the dimensions of the new and old parts and tighten to the vehicle manufacturer's torque specification. Component failure cannot be determined from noise alone. [1]
Applicability and limits
- Delphi general suspension technical information; no specific brand, model, year or powertrain type is stated, and no vehicle fitment assessment has been made. Scope: unknown [1]
