What to Do When the Steering Wheel of Baojun 630 Feels Heavy?

[DeAbel]

The steering wheel of the Baojun 630 feels heavy, and the specific reasons are as follows: 1. Deformation of the steering knuckle arm, lack of oil or damage to the steering knuckle thrust bearing, excessive tightness or lack of oil in the steering knuckle kingpin and bushing clearance, deformation of the front axle or frame causing misalignment of front wheel positioning, insufficient tire pressure. 2. Over-tight assembly of the steering gear bearing, excessive tightness in the meshing clearance of the transmission pair, over-tight assembly or lack of oil in the tie rod ball joints, bending of the steering shaft or main pipe causing friction or jamming, improper lubrication of the steering system, incorrect toe-in adjustment. Fault diagnosis and elimination: 1. Lift the front axle and turn the steering wheel. If the steering feels flexible, the fault lies in components such as the front axle and wheels. Because lifting the front axle eliminates the contact resistance between the wheels and the road surface when turning the steering wheel. At this time, carefully check whether the front tire pressure is too low, whether the front leaf spring is in good condition, and whether the frame is deformed, etc. 4. Lift the front axle and turn the steering wheel. If the steering still feels heavy, it indicates that the fault lies in the steering gear or steering linkage. At this time, the steering arm can be removed, and then the steering wheel can be turned again. If it still feels heavy, it indicates an internal fault in the steering gear, and the damaged parts should be repaired or replaced as needed.
