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 is a critical element in the vehicle’s steering system, directly influencing tire wear, driver comfort, and overall vehicle safety.
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 rubber compound is specially formulated to resist ozone cracking, UV degradation, and thermal aging, ensuring consistent performance across a wide temperature range from -40°C to +80°C.
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 precise dimensional tolerances eliminate the need for modifications, reducing installation time and labor costs. Whether you are performing a routine replacement or rebuilding a front axle assembly, this bushing provides the reliability and longevity that professional fleet operators demand.
In addition to its primary role in the tie rod assembly, the WG9925682102/4 bushing also contributes to overall vehicle stability during cornering and braking by minimizing unwanted deflection in the steering linkage. This results in more predictable handling, reduced driver fatigue, and improved safety margins, especially when operating heavily loaded vehicles on uneven roads.
The WG9925682102/4 bushing is manufactured to exacting OEM tolerances with a dimensional accuracy of ±0.05 mm, 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 steel sleeve is precision-ground to a mirror finish, reducing friction and ensuring smooth rotation of the tie rod end.
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 with a 10-micron coating for corrosion resistance, ensuring reliable performance in wet, salty, or dusty environments. Independent laboratory tests confirm that this bushing can endure over 5 million dynamic load cycles without failure, exceeding original equipment specifications.
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 provides a balance between comfort and control, adapting to varying road conditions for a consistently smooth driving experience.
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 outer diameter is engineered to provide an interference fit that eliminates the need for additional retaining clips or adhesives, ensuring secure retention under all operating conditions.
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 contributes to increased safety and productivity.
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 and extending vehicle service intervals.
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, especially when carrying heavy loads.
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 consistent performance also helps avoid unscheduled repairs and roadside breakdowns.
Environmental Resistance: The rubber compound is resistant to ozone, UV radiation, and common automotive fluids such as oil, grease, and brake fluid, ensuring reliable performance even in harsh industrial environments and extreme weather conditions.

Installation Tips & Best Practices:
The WG9925682102/4 bushing is produced using a proprietary injection-molding process that ensures uniform material density and consistent mechanical properties. The rubber compound is a blend of natural and synthetic rubber (NR/SBR) reinforced with carbon black for enhanced tensile strength and tear resistance. The steel inner sleeve is manufactured from high-grade carbon steel (C45E) and is zinc-plated to resist corrosion, with a surface hardness of HRC 45-50 to withstand high cyclic loads.
Every batch of WG9925682102/4 bushings undergoes rigorous quality testing, including dynamic fatigue tests (5 million cycles at ±3° angular deflection), thermal aging tests (168 hours at 100°C), and salt spray corrosion tests (240 hours). These tests confirm that the bushing meets or exceeds the original equipment specifications, providing consistent performance throughout its service life.
The bushing’s bonded construction uses a proprietary adhesive system that ensures the rubber remains firmly attached to the steel sleeve under extreme operating conditions, preventing separation and ensuring long-term reliability. This advanced manufacturing approach results in a component that offers superior dynamic characteristics, reduced noise transmission, and extended durability compared to generic aftermarket alternatives.
The WG9925682102/4 Tie Rod Bushing from SINOTRUK Sitrak is the definitive choice for fleet operators and owner-drivers who demand uncompromising quality, durability, and steering precision. As a genuine OEM-grade component, it guarantees a perfect fit, reliable performance, and extended service life—backed by SINOTRUK’s engineering excellence and decades of experience in heavy commercial vehicle manufacturing.
