Labwork 24.2" Torque Rod Assembly for Freightner Fits 16-15632-000, 16-18972-000

Key Features & Technical Advantages

• High-Strength Heavy-Duty Construction: Fabricated from premium, fatigue-resistant steel engineered to withstand heavy axle loads, continuous vibration, and harsh road conditions without bending or deforming.

• Corrosion & Rust Resistant Coating: High-grade protective surface finish shields the metal body against moisture, road salts, chemicals, and environmental rust for long-lasting durability.

• Optimized Axle Alignment & Tracking: Effectively stabilizes axle geometry, prevents axle wrap-up during acceleration and braking, and absorbs severe driving forces to protect adjacent suspension components.

• Enhanced Ride Stability & Handling: Straddle-mount design delivers balanced flex and articulation, reducing vehicle sway, cab movement, and premature tire wear.

Crucial Fitment & Compatibility Notice

Please Read Before Purchasing: Verify your suspension system type, torque rod length, and existing OEM part number before ordering. Professional installation and post-install axle alignment are highly recommended.

Common Symptoms of a Worn Torque Rod

• Cracked or Softened Bushings: Visible wear, separation, or dry rot on rubber/polyurethane end bushings.

• Excessive Axle or Cab Movement: Unwanted shifting, lunging, or shuddering during braking and acceleration.

• Uneven Tire Wear: Irregular tread scrubbing caused by improper tracking and axle misalignment.

• Increased Road Vibration & Noise: Loud clunking or knocking sounds when driving over bumps or during shifting.

• Handling Difficulties: Wandering steering or instability, especially when navigating turns.

Important Installation & Maintenance Notes

• Professional Installation Recommended: Torque rods require proper torque specifications and precise axle alignment to avoid premature component wear.

• Hardware & Bushings: Ensure proper alignment with mounting brackets and inspect all hardware prior to final torque tightening.

• Post-Installation Alignment: Always check and verify axle alignment after replacing torque rods.
