The WG9925682102/4 Tie Rod Bushing is a precision-molded rubber-and-steel composite component engineered to provide a durable, low-friction pivot point in the steering linkage of SINOTRUK Sitrak heavy trucks. It is installed between the tie rod end and the steering knuckle, allowing smooth articulation while isolating the chassis from road-induced vibrations and shocks. This bushing plays a pivotal role in maintaining steering geometry, reducing tire wear, and ensuring predictable vehicle behavior during cornering and braking.
Manufactured from high-grade synthetic rubber bonded to a precision-formed steel inner sleeve, this bushing offers excellent elasticity, fatigue resistance, and load-bearing capacity. Its advanced polymer composite formulation provides ten times the impact resistance of conventional rubber bushings, making it ideal for heavy-duty applications where durability is paramount. The steel sleeve is zinc-plated to prevent corrosion, while the rubber compound is formulated to resist oil, ozone, and extreme temperature variations from -40°C to +120°C, ensuring reliable performance in diverse climatic conditions.
The WG9925682102/4 bushing is a direct OEM replacement for original Sitrak and HOWO suspension components, ensuring seamless integration and restoring factory-spec steering geometry and ride quality. Its engineering precision eliminates the need for shims or modifications, significantly reducing installation time and ensuring a perfect fit every time.
The WG9925682102/4 bushing is manufactured to exacting OEM tolerances, ensuring a perfect fit with Sitrak C7H, C5H, and HOWO T7H steering knuckles and tie rod ends. Its self-lubricating polymer layer reduces friction by up to 40% compared to standard rubber bushings, minimizing wear and extending service intervals. The inner sleeve is machined to a surface finish of Ra 0.8 μm, ensuring smooth rotation and consistent torque transmission.
Built to withstand the punishing conditions of long-haul trucking and off-road operations, the WG9925682102/4 bushing features a specialized rubber compound that resists cracking, ozone degradation, and thermal aging. Its steel inner sleeve is zinc-plated for corrosion resistance, ensuring reliable performance in wet, salty, or dusty environments. The bushing has been tested to withstand radial loads exceeding 50 kN and angular misalignment up to 8 degrees without loss of performance.
By effectively dampening road shocks and minimizing play in the steering linkage, the WG9925682102/4 bushing delivers precise steering response, reduced driver fatigue, and improved tire wear. Its uniform load distribution design reduces stress concentrations, protecting adjacent steering components from premature failure. The bushing’s progressive spring rate characteristic ensures a comfortable ride under light loads while maintaining firm control during heavy cornering.
Designed for serviceability, the WG9925682102/4 bushing features precision alignment indicators that simplify proper positioning during assembly. No specialized tools are required, and the bushing can be installed using standard workshop equipment, reducing labor time and vehicle downtime. The bushing’s symmetrical design eliminates orientation errors, and the installation process typically takes less than 30 minutes per side.

Superior Vibration Dampening: The advanced rubber compound absorbs road shocks and isolates the cabin from harsh vibrations, significantly improving ride comfort and reducing driver fatigue during long hauls. This translates to higher productivity and safer driving.
Extended Component Life: By eliminating metal-to-metal contact and reducing friction, the WG9925682102/4 bushing protects tie rod ends, steering knuckles, and other suspension components from premature wear, reducing overall maintenance costs. Fleet operators report up to 50% longer steering component life after switching to this bushing.
Improved Steering Precision: The precise fit and low-friction design of the WG9925682102/4 bushing eliminate play in the steering linkage, delivering crisp, responsive steering control and enhanced vehicle stability at highway speeds. This reduces driver steering effort and improves lane-keeping ability.
Cost-Effective Maintenance: With a service life exceeding 100,000 kilometers, the WG9925682102/4 bushing reduces the frequency of replacement, lowering parts and labor costs over the vehicle’s lifetime. Its durability also minimizes vehicle downtime, keeping your fleet on the road and earning revenue.
Superior Thermal Stability: The rubber compound retains its mechanical properties across a wide temperature range (-40°C to +120°C), ensuring consistent performance in both freezing winters and scorching summers. This makes it ideal for fleets operating in diverse climates.
Environmentally Friendly: The bushing is manufactured using lead-free, RoHS-compliant materials, and its extended service life reduces waste generation. Additionally, the reduced friction contributes to lower fuel consumption, decreasing the vehicle’s carbon footprint.

Installation Tips:
Pro Tip: Always replace tie rod bushings in pairs (left and right) to maintain balanced steering characteristics and even tire wear. Inspect the tie rod ends and steering knuckle for wear during replacement, and replace any damaged components simultaneously.
Regular inspection of the WG9925682102/4 bushing is essential to ensure continued steering performance and safety. Check for visible signs of wear every 20,000–30,000 km, including cracks, swelling, or separation of the rubber from the steel inner sleeve. Excessive play in the steering linkage (more than 2–3 mm of lateral movement) indicates bushing wear and warrants replacement.
During routine maintenance, also inspect the tie rod ends and steering knuckle for any corrosion or damage that could compromise the bushing’s performance. If the vehicle exhibits wandering steering, uneven tire wear, or a clunking noise when turning, these are common symptoms of a worn tie rod bushing that should be addressed promptly.
For optimal service life, ensure that the steering system is properly lubricated and that all fasteners are torqued to manufacturer specifications. The WG9925682102/4 bushing is designed to be maintenance-free for its entire service interval, requiring no additional greasing or adjustments after installation.
Choosing the genuine WG9925682102/4 bushing from SINOTRUK Sitrak ensures that your vehicle receives a component engineered specifically for its suspension geometry and loading characteristics. Aftermarket bushings often use inferior rubber compounds or inaccurate steel sleeves, leading to premature failure, poor handling, and increased tire wear. The OEM bushing undergoes rigorous quality control, including dynamic load testing, thermal cycling, and salt-spray corrosion testing, to guarantee performance and longevity.
Moreover, the WG9925682102/4 bushing is backed by SINOTRUK’s engineering data and warranty, giving you confidence in its reliability. It is the same bushing installed on new Sitrak trucks at the factory, ensuring that your replacement part matches the original vehicle specifications. This consistency is vital for maintaining the vehicle’s original ride quality, handling, and safety.
Investing in genuine parts also helps preserve the resale value of your Sitrak truck, as potential buyers recognize the importance of using authentic components for long-term durability. With the WG9925682102/4 bushing, you are not just buying a part; you are investing in the continued performance and safety of your vehicle.
