Reliable Suspension Fastening: Sinotruk HOWO Thrust Rod Bolt (Q151B20180TF2)
In the world of heavy-duty logistics, the suspension system’s integrity depends on the smallest components. This Q151B20180TF2 Thrust Rod Bolt is a critical fastener specifically engineered for the lower thrust rod (V-stay or torque rod) of Sinotruk HOWO and Steyr trucks.
When your vehicle is hauling maximum loads over uneven terrain, the thrust rod absorbs massive lateral and longitudinal forces. Using a generic or low-grade bolt can lead to suspension misalignment or even catastrophic failure. This genuine Sinotruk part is forged from high-tensile alloy steel and heat-treated to withstand constant vibration and shear stress. It features a precision-cut thread for a secure, anti-loosening fit, ensuring your truck’s rear axle remains properly aligned under the most demanding conditions.

Installation Tips for the Q151B20180TF2 Bolt:
Preparation: Support the axle with a heavy-duty jack and ensure the thrust rod is not under tension.
Cleaning: Clean the mounting holes on the axle bracket and the thrust rod bushing. Any grit left inside will prevent the bolt from reaching its full clamping force.
Alignment: Align the thrust rod eye perfectly with the bracket hole. Do not force the Q151B20180TF2 bolt through with a hammer; this can damage the threads.
Torque Specs: Use a calibrated torque wrench. Since this is a critical suspension component, follow the Sinotruk service manual's specific torque settings (standardly requires high torque to ensure the bolt remains pre-loaded).
Locking: Always use a new lock nut or lock washer. We recommend inspecting these bolts every 10,000km for signs of fatigue or loosening, especially in mining applications.
