The steering bushing is an important component in the automotive steering system, mainly used to reduce friction and wear at the connection of the steering mechanism, and provide cushioning and shock absorption. The following is a detailed introduction about the steering bushing:
1. The function of the steering bushing
Reduce friction: Provide lubrication at connecting parts such as steering rods and swing arms to reduce direct friction between metal parts.
Buffer vibration: Absorb vibrations and impacts from the road surface to enhance driving comfort.
Maintain positioning accuracy: Ensure the stability of the steering geometry structure and avoid steering wheel misalignment or reduced maneuverability due to looseness.
Extend lifespan: Protect the metal components of the steering system and reduce wear and tear.
2. Common types
Rubber lining: The most common, low-cost and elastic, but it is prone to aging and cracking after long-term use.
Polyurethane lining: more wear-resistant and oil resistant, with better performance than rubber, commonly used for modification or high-performance vehicles.
Hydraulic liner: filled with hydraulic oil for better shock absorption, commonly used in luxury car models.
Metal lining (such as bronze): used for high load areas, but requires regular lubrication.
3. Symptoms of malfunction
Abnormal noise: making a "creaking" sound when turning (due to rubber aging or broken lining).
Loose steering wheel: increased virtual position, inaccurate handling.
Vehicle deviation: The wear of the lining leads to abnormal positioning parameters.
Chassis vibration: The damping effect decreases, and the transmission of road vibrations is significant.
4. Replacement steps:
Lift the vehicle and remove the tires or related connecting rods.
Remove the old lining (may require specialized tools or a press).
Clean the installation position and apply lubricant (such as silicone grease).
Press in the new liner to ensure proper alignment.
Re do the four-wheel alignment.
matters needing attention:
After replacement, tighten the bolts to the standard torque.
Avoid using inferior bushings, as they may quickly fail.
5. Key points for purchasing
Matching vehicle model: Select the original factory or certified brand.
Material selection: Rubber is sufficient for daily driving, while polyurethane can be considered for sports car models.
After sales guarantee: Priority should be given to products that provide warranty.
6. Maintenance points
Regularly clean the chassis to prevent mud and sand from accelerating the wear of the lining.
Avoid prolonged parking in extreme temperature or humid environments.
If cracks, deformations, or dislodgements are found in the lining, replace it promptly.
