1.What is an Upper Ball Joint?
1).Structure and Function of Upper Ball Joint
The upper ball joint is the core component of the automobile suspension system. It connects the control arm with the steering knuckle and undertakes three core functions:
Flexible Steering: Multi-angle rotation is realized through spherical design to ensure accurate steering wheel control.
Load Support: Withstands vertical and lateral impact force of the vehicle to ensure driving stability.
Shock Absorption: Cooperates with the suspension system to reduce road vibration transmission, improving driving comfort.
2).Common Faults and Replacement Signals
Abnormal Noise: “Creak” or “click” sounds on bumpy roads.
Loose Steering: Increased steering wheel free play or vehicle pulling to one side.
Uneven Tire Wear: Ball head wear causes positioning inaccuracies.
Seal Sleeve Rupture: Grease leakage accelerates internal wear.
Recommended Maintenance: Replace suspension system every 80,000-100,000 km or when symptoms occur to prevent cascading damage.

FAQ:
The normal service life is 80,000 to 100,000 km, but it may be shortened to 50,000 km under bad road conditions or improper installation. It is recommended to check the condition of the seal sleeve regularly.
Professional tools (press, torque wrench, etc.) are required, which are recommended to be operated by the repair shop to avoid damaging the control arm or affecting the four-wheel positioning.
Retail MOQ 50 pieces, wholesale orders can be negotiated up to 10 pieces, support mixed model procurement.
