Truck spherical joint: faults, diagnostics and fast delivery of original spare parts1
2026-04-03
The spherical joint is an important element of the steering and suspension of a truck, responsible for transmitting forces and ensuring the mobility of the suspension and steering units. Without a properly functioning ball joint, the truck's steering becomes unstable, and the durability of the suspension and steering gear is significantly reduced. In our catalog **[truck spare parts]We offer only original spherical joints for popular Chinese truck brands: Howo, Dongfeng, SINOTRUK, FAW and others.
Original spherical joint for trucks
All original spherical joints are made from high quality alloy steels and sealing materials and undergo strict quality control at the factory, ensuring strength, movement and durability in harsh operating conditions. In addition to spherical joints, we also offer other important steering and suspension parts, such as **[seal for spherical joint], steering levers and hubs, which are often needed when repairing a spherical joint.
Common spherical joint malfunctions and their diagnosis
Repair of a spherical joint on a truck
Fault 1: Spherical joint wear and lubricant leakage
Reasons:Long-term operation, penetration of dirt and moisture into the unit, wear of the spherical joint sealing ring, use of poor-quality lubricant, mechanical shock and overload.
Symptoms:The sound of knocking or creaking when turning the steering wheel and driving on uneven roads, play in the steering, unstable movement of the truck (drift), visible traces of grease around the spherical joint, wear of belts and hubs.
Solution:Inspect the spherical joint for wear and damage, check the condition of the O-ring, replace the worn spherical joint with an original one. We recommend simultaneously replacing the **[seal for the spherical joint](https://www.mettleadauto.com/ru/ball-joint-seal)** and applying a specialized lubricant.
Fault 2: Spherical joint is stuck or stuck
Reasons:The unit is clogged with dirt and rust, lack of lubrication, corrosion of the internal parts of the spherical joint, damage to the pin and support, improper installation.
Symptoms:Difficulty turning the steering wheel, hard steering, uneven wheel wear, vibration in the steering wheel when driving, inability to turn the truck completely.
Solution:Disassembling and cleaning the spherical joint, removing rust and dirt, applying lubricant, or completely replacing it with the original spherical joint. Before installing a new spare part, check the condition of the mating components (levers, hubs).
Fault 3: Rupture or damage to the spherical joint housing
Spherical joint parts - pin and seal
Reasons:Strong mechanical shocks, overloads when transporting heavy loads, faulty suspension, use of non-original spare parts with low strength, corrosion.
Symptoms:Visual cracks and damage on the spherical joint housing, complete failure of the steering (in extreme cases), severe play, knocking noise whenever the truck moves.
Solution:Emergency replacement of a damaged spherical joint with an original one. After replacement, we recommend checking the wheel geometry and steering to prevent repeated damage to the spherical joint.
