Frequently Asked Questions About Peterbilt 387 Torque Rods & U-Bolts
What years and models of Peterbilt 387 do these torque rods and U-bolts fit?
Our torque rods and U-bolts are designed to fit Peterbilt 387 models from 2000 to 2010. However, compatibility can vary based on your specific suspension configuration. We recommend checking your truck's VIN and current suspension setup before ordering. If you're unsure, our customer service team can help verify fitment with your truck's specifications.
Are these torque rods greaseable or maintenance-free?
We carry both greaseable and maintenance-free torque rod options. Greaseable torque rods require periodic lubrication but typically last longer with proper maintenance. Maintenance-free versions use sealed bushings that don't require greasing but may need replacement sooner. Most drivers prefer greaseable for heavy-duty applications and maintenance-free for convenience.
What's the difference between OEM and aftermarket torque rods in terms of quality?
Our aftermarket torque rods meet or exceed OEM specifications and are manufactured from high-strength forged steel. The main differences are price and bushing material options. Aftermarket rods often feature upgraded polyurethane bushings that last longer than standard rubber, while OEM typically uses rubber bushings. Both options provide reliable performance when properly installed.
Do I need special tools to install torque rods and U-bolts?
Basic installation requires standard shop tools including a torque wrench, socket set, and jack stands. However, removing old torque rods often requires a pickle fork or bushing removal tool. U-bolt installation is straightforward but requires proper torque specifications (typically 450-500 ft-lbs). We recommend professional installation if you don't have experience with suspension work.
How do I know when my torque rods or U-bolts need replacement?
Common signs include irregular tire wear, wandering steering, clunking noises from the suspension, or visible bushing deterioration. For U-bolts, look for stretching, thread damage, or rust. During inspection, check for play in the torque rod bushings by prying with a bar. Any movement indicates wear. Most torque rods last 200,000-300,000 miles with proper maintenance.
