Peterbilt 367 Torque Rods & U-Bolts

Frequently Asked Questions About Peterbilt 367 Torque Rods & U-Bolts

What do torque rods and U-bolts actually do on my Peterbilt 367?

Torque rods connect the axle housing to the truck frame, controlling axle movement and absorbing driveline torque during acceleration and braking. U-bolts clamp the axle housing to the leaf springs, holding the suspension components together securely. Both parts work together to keep your suspension and drivetrain properly aligned and stable under load.

How do I know if my torque rods or U-bolts need to be replaced?

Common signs include a clunking or knocking noise when accelerating or braking, noticeable axle shift or misalignment, uneven tire wear, or visible cracking, rust, or looseness in the bushings and mounting points. If you notice play in the torque rod bushings or stretched, corroded U-bolts, it is time to inspect and likely replace them.

Will these torque rods and U-bolts fit my specific Peterbilt 367 configuration?

Fitment depends on your truck's axle type, suspension setup, and model year, since the 367 was built with different axle and suspension configurations over its production run. Always check the listed specifications, such as bolt length, thread size, and mounting dimensions, against your truck's OEM parts before ordering, and reach out to our team if you're unsure.

Are these parts OEM or aftermarket, and does it matter?

Our catalog includes both OEM and quality aftermarket options. Aftermarket torque rods and U-bolts are manufactured to match OEM specs for fit and durability, often at a lower cost. If you need an exact factory match, look for listings noted as OEM; otherwise, a well-made aftermarket replacement will perform the same job reliably.

Can I install torque rods and U-bolts myself, or should I have a professional do it?

Experienced DIY mechanics with the right tools, such as a torque wrench and proper lifting equipment, can often handle this job. However, torque rods and U-bolts affect axle alignment and suspension integrity, so bolts must be tightened to the correct torque spec and alignment should be checked afterward. If you're not confident in doing this safely, having a professional shop handle the installation is a smart choice.
