What are the main inspection items for the major components of the automotive running gear system?

The running gear system includes components such as the frame, front axle, drive axle housing, wheels (steering wheels and drive wheels), suspension (front suspension and rear suspension), etc. Below are the inspection items for automotive parts: 1. Applicable Products: Front and rear plastic (metal) bumpers, metal & non-metal fenders, mirror housings, engine hoods, exterior trims, impact strips, etc. 2. Testing Items: Mechanical performance, stiffness and strength, deformation testing, surface thickness testing, adhesion testing, corrosion resistance testing, wear resistance testing, high and low temperature environmental testing/UV aging testing, UV/xenon arc aging, high and low temperature mechanical testing, environmental mechanical performance testing, sand/dust/rain/stone impact testing, metallographic testing, non-destructive testing, comprehensive performance testing/fatigue durability testing, etc.
I usually pay close attention to safety when driving, and I’ve found that the inspection of the main components of the vehicle's running gear should focus on several key areas. First, the suspension system must be checked—look for oil leaks or deformations in components like shock absorbers and springs. If the car body shakes excessively when driving over rough roads, there might be an issue. Steering components should also not be overlooked; inspect the tie rod ends and steering knuckles for wear. If the steering wheel feels too loose or makes unusual noises when turning, it could be dangerous. Tires and rims require even more attention: tire pressure must be maintained at the standard value, and tread depth should be monitored. If the tread is below 1.6 mm, it’s time to replace the tires to avoid slipping in rainy conditions. Finally, the clearance of the wheel hub bearings is crucial—lift the car and shake the tires to check for looseness. I always recommend regular wheel alignment, about once every six months, to prevent issues like misalignment or blowouts. Safety comes first—saving a little money on repairs is not worth the risk when preventive checks can avoid major troubles.
