Find Reliable Steering Parts for the Peterbilt 359
We carry a wide range of replacement components to help rectify any steering troubles you might have, including:
Power Steering Pump â The heart of your steering system. It pushes hydraulic fluid under pressure, giving you smooth, effortless control even when fully loaded.
Drag Link â The link between your steering gear and the front wheel assembly. A worn drag link can cause play in the wheel and sluggish response.
Cross Tube (Tie Rod Assembly) â The stabilizing bar that keeps both front wheels aligned and turning together. It helps maintain straight tracking and prevents uneven tire wear.
Tie Rod Ends â The flexible joints that connect your steering linkage to the knuckles. When worn, they cause sloppy steering and reduced road feel.
King Pin Kits â The heavy-duty pivot points that allow your front wheels to rotate under load. Fresh king pins bring back tight, steady steering performance.
Steering Stabilizers & Accessories â Reduce vibration, absorb shock, and improve steering feel for smoother control on long stretches and rough terrain.

Will these steering parts fit my specific year Peterbilt 359?
Most steering components for the Peterbilt 359 are compatible across the entire production run from 1967 to 1987. However, there are some exceptions. Early models (1967-1972) may have different steering box mounting patterns and column lengths. Always verify your truck's serial number and year when ordering steering boxes, drag links, or steering shafts. Tie rod ends, pitman arms, and most steering wheels are typically universal across all 359 model years.
What's the difference between manual and power steering components for my 359?
Manual steering boxes use a different gear ratio (typically 24:1) compared to power steering boxes (16:1), and they cannot be interchanged. Power steering systems require a steering pump, hoses, and a different steering box with hydraulic ports. If converting from manual to power steering, you'll need the complete kit including brackets, pulleys, and reservoir. The steering shaft and column are the same for both systems, but the steering wheel effort is significantly reduced with power steering.
How difficult is it to replace the steering box, and what tools do I need?
Replacing a steering box typically takes 3-4 hours for an experienced mechanic. You'll need a pitman arm puller, basic hand tools, and potentially a steering wheel puller. The most challenging part is usually removing the old pitman arm, which often requires heat and penetrating oil. Make sure to mark the steering shaft position before removal to maintain wheel alignment. Many drivers recommend having a helper to support the box while removing the mounting bolts.
Are aftermarket steering wheels legal, and do they affect airbag systems?
The Peterbilt 359 never came with airbags from the factory, so aftermarket steering wheels won't affect any safety systems. Any DOT-approved steering wheel is legal for highway use. Popular upgrades include 18-inch and 20-inch chrome or wood grain wheels. Make sure to order the correct horn button kit for your chosen wheel, as universal kits may not fit properly. The steering wheel hub adapter must match your specific column splines (typically 36 spline for most 359s).
Why is my steering loose or wandering, and which parts should I check first?
Steering play usually starts with worn tie rod ends, which should be checked first as they're the most common failure point. Next, inspect the drag link ends and pitman arm for play. A worn steering box will show excessive play when turning the steering wheel with the engine off. The steering shaft U-joints can also develop slack over time. For proper diagnosis, have someone turn the wheel back and forth while you watch each component. Any visible movement at the joints indicates wear. Most mechanics recommend replacing tie rod ends every 100,000 miles as preventive maintenance.
