The automotive drivetrain system mainly includes tires, wheel hubs, suspension (such as shock absorbers, springs, control arms), axles, steering knuckles, and other components. The selection of these parts directly affects handling, comfort, and driving safety.
Confirm Vehicle Compatibility
It is necessary to check the vehicle brand, model, year, and original factory parameters (such as tire specifications, wheel hub bolt pattern, suspension type) to ensure the parts are fully compatible. Even the same model from different years may have design differences.
Prioritize Genuine and Well-Known Brands
Genuine parts have stable quality and clear warranties; well-known brands such as Bosch, MacPherson, Continental, Hankook, and Leichi offer more assurance in materials and craftsmanship.
Check Key Physical Details
Geometric dimensions: shafts, wheel hubs, springs, etc., should be free of bending or warping;
Joint areas: free of burrs, dents, and cracks;
Rotating components (such as wheel hub bearings): rotation should be smooth without sticking;
Protective layers: rust-proof oil and wax packaging should be intact without leakage.
Pay Attention to Safety Certifications and Warranties
Choose products with certifications such as ISO9001 and 3C, and keep the purchase receipts.
