Frequently Asked Questions About Kenworth W990 Torque Rods & U-Bolts

What are the weight ratings and material specifications for W990 torque rods?

Our Kenworth W990 torque rods are manufactured from high-strength steel alloy with a minimum tensile strength of 110,000 PSI. Standard torque rods for the W990 are rated for applications up to 46,000 lbs rear axle capacity. Heavy-duty options are available for severe service applications. All torque rods feature greaseable bushings with natural rubber compounds rated for -40?F to 180?F operating temperatures.

Will these torque rods and U-bolts fit my specific W990 model year?

These torque rods and U-bolts are designed to fit all Kenworth W990 models from 2018 to present. The W990 uses the same suspension mounting points across all model years, making these parts universally compatible. However, verify your specific axle configuration (single vs. tandem) and suspension type (Kenworth AG400L, AG460, or Neway ADZ) before ordering to ensure you select the correct length and style.

Do I need special tools or professional installation for torque rod replacement?

While torque rod replacement can be performed with standard shop tools, you'll need a torque wrench capable of 450-500 ft-lbs for proper installation. A pickle fork or bushing removal tool is recommended for removing old torque rods. Installation typically takes 2-3 hours per axle. Critical torque specifications: U-bolts should be torqued to 300-350 ft-lbs, and torque rod mounting bolts to 450-500 ft-lbs. Always replace torque rods in pairs to maintain proper axle alignment.

What's the difference between adjustable and fixed-length torque rods for the W990?

Fixed-length torque rods are OEM-style replacements that maintain factory suspension geometry and are ideal for standard applications. Adjustable torque rods allow for precise axle alignment and are recommended if you've modified your suspension height, experienced uneven tire wear, or need to correct thrust angle issues. Adjustable rods feature left and right-hand threads with jam nuts and typically offer 2-3 inches of adjustment range.

How often should I inspect and replace torque rods and U-bolts on my W990?

Inspect torque rods every 50,000 miles or during regular PM services. Look for cracked or torn bushings, bent rod bodies, or excessive play in the joints. U-bolts should be checked for stretching, corrosion, or thread damage every 100,000 miles. Replace torque rods when bushings show visible deterioration or if you notice wandering, dog-tracking, or irregular tire wear. U-bolts should be replaced if threads are damaged or if they've been loosened and retorqued more than twice.
