9483502705 - Track control arm, control/trailing arm OE number by MERCEDES-BENZ

This track control arm (trailing arm) with OE number 9483502705 is a key load-bearing component for the chassis suspension of Mercedes-Benz heavy-duty trucks. It differs functionally from V-stay torque rods. It mainly transmits longitudinal force, buffers impact loads between the frame and axle, and limits the longitudinal bounce of the axle. When the vehicle starts, brakes or travels on bumpy roads, it absorbs road vibration, balances suspension force and disperses stress to slow down fatigue aging of other chassis parts. It fits multiple Mercedes-Benz commercial heavy trucks and is widely used for long-haul tractors, engineering dump trucks, cement mixers and other heavy-load applications. Manufactured by precision die forging and equipped with high-durability composite rubber bushings, it is produced strictly according to original drawing tolerances with precise positioning for direct replacement. It is an ideal choice for fleet maintenance and chassis overhaul, balancing durability and installation efficiency.

① Forged arm body made of alloy structural steel with uniform internal structure, excellent fatigue resistance and crack resistance under long-term heavy load. ② Composite rubber bushing resists high & low temperature and tearing, delivers outstanding shock absorption and reduces impact noise from chassis. ③ Original-standard dimension benchmark, accurate hole spacing and angle. No grinding or modification required for fast and convenient replacement. ④ High-adhesion epoxy coating protects against mud, water and salt corrosion for longer service life on construction sites and coastal routes. ⑤ Effectively restricts longitudinal axle movement, shares load of leaf springs and reduces wear on leaf springs and connecting ball joints.

Mercedes-Benz Actros MP2, MP3 and Axor series heavy trucks, chassis code 940, 942; suitable for 6×4 tractors, dump trucks and mixer trucks.

1. Q: Can this control arm interchange with 9483502205 V stay torque rod? A: Not interchangeable. They differ in structure and force direction. The V stay torque rod is for lateral limitation while this one is a longitudinal trailing arm, not for substitution.
2. Q: What common faults will appear if the control arm is damaged? A: Loud clunking noise from chassis when passing potholes, longitudinal axle shifting, obvious jerk at start and chassis shaking during acceleration and deceleration.
3. Q: Can the bushing be replaced separately once it ages? A: Yes. If the arm body is not deformed, only replacing the rubber bushing works to cut repair cost.
4. Q: Is rear axle alignment necessary after replacing this control arm? A: Rear axle calibration check is recommended to avoid forward-backward axle offset and abnormal tire wear.
5. Q: Is it suitable for heavy-duty construction site operation? A: Yes. The forged arm body is impact-resistant and the rubber bushing is tear-resistant, perfect for heavy-load working conditions with frequent bumps.
