Product Uses
Here are specific application scenarios of Steering Tie Rod:
1. Daily Urban Commuting
Ideal for vehicles used in daily urban travel (average 50-80km daily mileage). The component’s 10,000+ fatigue test certification ensures it maintains stable steering precision under frequent stop-and-go and low-speed maneuvering. Compliant with ISO 9001, it eliminates loose steering or delayed response—common issues in high-frequency urban use—guaranteeing daily driving safety.
2. Suburban & Mountain Road Driving
Perfect for vehicles navigating suburban gravel roads or mountainous curves. Its 30% longer service life than industry averages (backed by IATF 16949 tests) resists wear from bumps and uneven terrain. The 0.02mm CNC machining precision ensures instant steering response, critical for avoiding risks when cornering on winding mountain roads.
3. Light Commercial Vehicle Operations
Suitable for light commercial vehicles (e.g., delivery vans) with frequent loading and start-stop cycles. It withstands a maximum bearing torque of 25 N・m (verified via Shimpo torque tests), handling the extra steering load from cargo weight. The electrophoretic coating also prevents corrosion from road grime, maintaining performance even with 6-8 hours of daily operation.
4. Extreme Climate Environments
Reliable in harsh climates: -40℃ cold regions (e.g., northern high latitudes) and 120℃ hot coastal areas. It passed 500-hour ASTM B117 salt spray tests, so the coating resists rust from sea salt. The 45# steel material remains rigid without brittleness in low temperatures, ensuring no steering failure in extreme weather.
Product Operate Guide
Prepare tools: a wrench and a torque wrench (to meet precision requirements). First, safely lift the vehicle and remove the old component after checking steering system stability.
Install the A3401108: fasten it to the steering rack, tightening to 25 N·m (per Shimpo torque test standards, compliant with IATF 16949).
Post-installation: test steering—ensure no looseness or abnormal noise. For safety, we recommend professional technicians operate; this cuts installation time by ~30% vs. unskilled attempts.
