Possible reasons for abnormal sound of a stabilizer:

Loose part: The fixing screw or connection of the stabilizer bar is loose, causing friction or knocking sound during drives.

Wear: The ball head, bearing, or joint of the stabilizer bar is heavily worn, causing friction between metals and abnormal noise.

Oil seal leakage: The lubricating oil seal in the stabilizer bar is damaged or broken, resulting in a lack of lubrication on the friction surface and harsh friction sound.

Insufficient pre-tightening load: The pre-tightening load of the stabilizer bar is insufficient of absent, resulting in loose part, friction, and abnormal noise.

Excessive wear: Excessive wear at the connection between the pole head and suspension or aged and damaged rubber parts can cause instability and abnormal noise in the suspension system.

Oil seepage: The dust cover or sealing ring on the stabilizer bar is damaged, and consequently dust and water enter and cause abnormal noise.

Solutions to abnormal of a stabilizer bar:

Inspect fasteners: First, check if the fasteners of the stabilizer bar are loose, including bolts and nuts, and make sure they are firmly connected.

Apply lubricant: Lubricating the ball joint, bearing, and other components of the stabilizer bar can reduce friction between metals and eliminate abnormal noise.

Replace worn parts: If the ball head, bearing, or joint of the stabilizer bar is heavily worn, it should be replaced with a new part in time to eliminate abnormal noise.

Replace sealing parts: If the dust cover or sealing ring on the stabilizer bar is damaged, it should be replaced in time to keep dust and water from entering and causing abnormal noise.

Adjust pre-tightening load: Check the pre-tightening load of the stabilizer bar, and adjust or replace the part with failed pre-tightening to ensure stable fastening of the components and eliminate abnormal noise.

Check other issues: If the above steps cannot solve the problem of abnormal noise, it may be necessary to further inspect other components of the suspension system, such as spring and shock absorber, in order to identify the real cause of the abnormal noise.

Advantages of vika STO stabilizer bar:

1. The vika STO stabilizer bar uses a new two-layer structure to reduce the possibility of pull-off, wear, and breaking.

2. A precision forged steel ball with higher strength is adopted, leading to a larger stress area.

3. The diameter of vika STO stabilizer bar has been increased from the original 10 mm to 11 mm, resulting in improved product pull-off resistance.

4. Larger swing angle: The ball pin swing angle of vika STO stabilizer bar is increased from 31° to 34°.
