Product Introduction

Structure

This V push rod ball joint is a composite assembly consisting of a main joint body and a set of replacement seals. The main body features a forged steel bracket with two mounting holes, a central high-damping rubber core vulcanized between precision-machined steel sleeves, and an integrated ball joint mechanism. The accompanying kit includes two black rubber seals and a snap ring, designed for maintenance and replacement to restore sealing performance. The steel components are finished with a corrosion-resistant coating, while the rubber core and seals are formulated for durability and flexibility.

Performance

The forged steel bracket provides exceptional strength and rigidity, capable of withstanding the heavy loads and stresses of heavy-duty truck suspension systems. The rubber core is made from a high-grade natural rubber compound, offering excellent vibration damping, fatigue resistance, and resistance to oil, chemicals, and ozone degradation. The rubber seals are precision-engineered to maintain a tight, leak-proof seal, even in temperatures ranging from -40°C to 120°C, ensuring long-term reliability in diverse operating conditions.

Core Function

1. Serves as a flexible connection point in the V push rod assembly, allowing for articulation and load transmission between the axle and frame while isolating vibrations.

2. Maintains the precise alignment of the suspension system, ensuring stable wheel positioning and preventing abnormal tire wear.

3. Protects the internal ball joint mechanism from contamination and wear via the rubber seals, extending the service life of the assembly.

4. Enhances vehicle stability and handling by providing a durable, reliable connection that can withstand the extreme conditions of heavy-duty operation.

V Push Rod Ball Joint WG9725529213 – Sinotruk Sitrak OEM Suspension Component

When your heavy-duty truck’s suspension system demands precision-engineered components, the V Push Rod Ball Joint WG9725529213 delivers exactly what you need. Designed specifically for Sinotruk Sitrak commercial vehicles, this ball joint serves as the critical pivot point within the V-shaped thrust rod assembly — connecting the chassis frame to the axle while absorbing road shocks and lateral forces. As a result, your truck maintains directional stability, even under the heaviest payloads.

At Mettlead, we supply this genuine-spec part directly from our factory in China, which means you get OEM-matching quality at a competitive wholesale price. Whether you’re restocking your warehouse or sourcing for a fleet overhaul, this ball joint is ready to ship with fast, reliable delivery worldwide.

Key Features and Benefits of the WG9725529213 Ball Joint

This isn’t just another replacement part sitting on a shelf. The WG9725529213 ball joint is engineered to handle the punishing conditions that heavy-duty trucks face daily. Here’s what makes it stand out:

• Precision-Forged Ball Stud: The hardened steel ball stud provides a smooth, low-friction pivot that resists wear — even after hundreds of thousands of kilometers on rough terrain.
• Heavy-Duty Dust Boot: A reinforced rubber seal keeps contaminants out and grease in, significantly extending the joint’s service life.
• High Load Capacity: Engineered to withstand the axial and radial forces generated by fully loaded Sitrak trucks, so you won’t see premature failure under stress.
• OEM-Spec Dimensions: Matches the original WG9725529213 specifications precisely, ensuring a bolt-on fit with no modifications required.
• Corrosion-Resistant Finish: Surface treatment protects against rust and oxidation, which is especially important for trucks operating in humid or coastal environments.

In other words, this ball joint keeps your V push rod assembly functioning smoothly, reduces maintenance downtime, and ultimately protects your bottom line.

Application Scenarios – Compatible Truck Models

The V Push Rod Ball Joint WG9725529213 is specifically designed for the suspension V-type thrust rod system in the following Sinotruk heavy-duty truck series:

• Sitrak C7H – Long-haul tractor units and heavy cargo configurations
• Sitrak C5H – Medium-to-long distance logistics and distribution trucks
• HOWO T7H – High-horsepower heavy-duty tractors and dump trucks
• HOWO T5G – Regional distribution and construction-site vehicles

Within these vehicles, the ball joint sits at the connection point between the V-shaped thrust rod and the vehicle frame or axle bracket. Its primary role is to allow controlled angular movement while transmitting braking and acceleration forces between the axle and chassis. Additionally, it absorbs vibrations and road impacts, which protects other suspension components from excessive stress.

Frequently Asked Questions

What are the signs that the WG9725529213 ball joint needs replacement?

You’ll typically notice clunking or knocking sounds from the suspension when driving over bumps. In more advanced cases, the truck may exhibit unstable handling or uneven tire wear. If the dust boot is torn or grease is leaking from the joint, replacement should happen immediately — because once contaminants enter the bearing surface, wear accelerates rapidly.

Is this ball joint compatible with both front and rear V push rods?

The WG9725529213 is designed for the V-type thrust rod assembly as specified by Sinotruk for the listed models. However, front and rear thrust rods may use different ball joint part numbers depending on the specific vehicle configuration. Therefore, we recommend confirming your VIN or checking the original part number stamped on your existing joint before ordering.

How does this part compare to the original Sinotruk factory component?

Our WG9725529213 ball joint is manufactured to OEM-equivalent specifications — same dimensions, same material grades, same heat treatment processes. The difference is price: because we supply factory-direct from China without intermediary markups, you typically save 30–50% compared to purchasing through official dealer channels.

What is the expected service life of this ball joint?

Under normal operating conditions and with proper greasing intervals, this ball joint typically lasts between 150,000 and 250,000 kilometers. That said, service life depends heavily on road conditions, payload frequency, and maintenance habits. Trucks operating primarily on paved highways will see longer life than those running on unpaved construction sites.

Can I order a sample before committing to a bulk purchase?

Absolutely. We encourage sample orders so you can verify fitment, finish quality, and packaging before scaling up. Sample lead times are typically 3–5 business days, and the cost can be credited toward your first bulk order.
