Frequently Asked Questions About Peterbilt 330/335/337 Steering Parts & Acc.

What years and specific models are these steering parts compatible with?

Our steering parts are designed to fit Peterbilt 330, 335, and 337 models from 2005 through current production years. However, compatibility can vary based on specific configurations like power steering type (TRW vs. Sheppard) and whether your truck has a set-back or set-forward axle. We recommend checking your OEM or calling our tech support at 1-888-875-7787 with your truck's serial number to ensure exact fitment before ordering.

Are these aftermarket steering components as durable as OEM parts?

We carry both genuine OEM and high-quality aftermarket steering components. Our aftermarket parts meet or exceed OEM specifications and are manufactured by trusted brands like TRW, Moog, and Spicer. These parts undergo rigorous testing for commercial vehicle applications and typically carry warranties ranging from 1-3 years. Many fleet operators report equal or better longevity compared to factory parts, especially with our heavy-duty upgraded options.

What tools and experience level are needed to install steering components?

Installing steering components like tie rod ends, drag links, and steering gear boxes requires intermediate to advanced mechanical skills and proper tools including a ball joint separator, torque wrench, and alignment equipment. Most steering shaft and u-joint replacements can be completed in 2-4 hours with basic hand tools. However, any work affecting steering geometry requires professional alignment afterward. We strongly recommend professional installation for steering gear boxes and pitman arms to ensure safety and proper operation.

How do I identify which steering gear box or power steering pump I need?

The easiest way to identify your steering components is by locating the part number tag on your existing unit. Steering gear boxes typically have a metal tag on the housing showing the model number (like TAS65 or RCS55). Power steering pumps will have similar identification. Common variations include different input shaft splines (36 vs. 40 spline) and pressure ratings. If tags are missing or unreadable, provide us with your OEM and we can cross-reference the correct parts through Peterbilt's database.

What are the warning signs that steering components need replacement?

Common indicators include excessive play in the steering wheel (more than 2 inches of free play), wandering or pulling while driving, uneven tire wear on the front axle, grinding or whining noises when turning, and visible fluid leaks from the steering gear or pump. For safety-critical parts like tie rod ends and drag links, any visible wear, looseness, or boot damage warrants immediate replacement. Regular inspections during PM services can catch these issues before they become dangerous or cause secondary damage to other components.
