Steering components explained

What each part between your steering wheel and your front tires does, how it wears, and what to look for.

Simplified top-down diagram of a solid-axle steering layout A steering box on the driver-side frame rail turns a pitman arm. A drag link runs from the pitman arm to the passenger-side knuckle, a tie rod connects both knuckles, a track bar runs from the frame to the axle, and a steering stabilizer runs between the axle and the tie rod.

Simplified, not to scale. This shows a “crossover” style layout. Factory linkage design differs between Ram generations, and some trucks connect the drag link to the tie rod instead of the knuckle. Your service manual shows your exact layout.

Follow the path from wheel to tire

When you turn the steering wheel, the steering shaft turns the input of the steering box. The box multiplies your effort (with help from hydraulic power steering) and swings the pitman arm. The pitman arm pushes and pulls the drag link, which turns one steering knuckle. The tie rod ties the two knuckles together so both wheels turn. Meanwhile, the track bar keeps the axle centered under the truck, and the stabilizer damps sudden movements.

Every connection along that path is a place where play can develop.

Steering shaft & joints

Connects the steering column to the steering box, usually with one or more U-joints or a slip section. Wear here feels like a slight lag or clunk in the steering wheel. Check by watching the shaft joints during a dry-park test.

Steering box (steering gear)

Solid-axle Rams use a recirculating-ball steering box bolted to the driver-side frame rail. Inside, a worm gear and ball nut drive a sector shaft, which the pitman arm is splined to. Common issues:

  • Internal wear showing up as play between the input and the pitman arm.
  • Seal leaks at the input or sector shaft.
  • Mounting problems: loose bolts, or the frame flexing and cracking around the box under heavy steering loads. This is a widely discussed issue on Rams with large tires and hard use.

A steering box brace ties the box's sector shaft area to the opposite frame rail to reduce flex. Dodge Off Road makes steering braces for several Ram generations.

About adjusting the box. Many boxes have an adjustment screw, and tightening it is a popular “fix” for play. Be careful: over-tightening can cause binding, poor return to center, and accelerated wear, and most play is usually somewhere else anyway. Follow your factory service manual's procedure, or leave it to a shop.

Pitman arm

The arm that converts the box's rotation into push-pull motion for the drag link. It's splined to the sector shaft and held with a large nut. Problems are usually a worn joint at the drag link end, a loose nut, or on lifted trucks the wrong arm for the geometry.

Runs from the pitman arm to the steering. Depending on the design, it goes to a knuckle or to the tie rod. It has joints at each end and usually an adjuster sleeve used to center the steering wheel. Factory drag links take a lot of load with big tires. Bent links and worn ends are common on hard-used trucks.

Tie rod & tie rod ends

Connects the two steering knuckles so both front wheels turn together. Its length sets the toe alignment. Worn ends cause wandering and uneven tire wear. A bent tie rod changes toe and can make the truck feel darty. Heavier-duty aftermarket tie rods are common on trucks with large tires.

Track bar

Also called a Panhard bar. It runs across the truck from a frame bracket on one side to the axle on the other, keeping the axle centered laterally. Because it controls side-to-side axle movement, a worn or loose track bar is one of the most common causes of wandering and death wobble on solid-axle Rams. Check the bushings or joints, the bolts, and the mounting holes in both brackets for elongation. See the track bar category at Dodge Off Road for Ram-specific bars.

Steering stabilizer

A shock absorber mounted between the axle and the steering linkage. It damps sudden kicks from bumps and tire imbalance. It's useful, especially with heavy tires, but it can't make worn parts tight. If a new stabilizer “fixed” your wobble, keep looking for the loose part.

Knuckles, ball joints & wheel bearings

The steering knuckles pivot on ball joints at the ends of the axle, and the hubs/wheel bearings bolt to them. Worn ball joints or bearings allow the wheel to move independently of the steering, and they often contribute to wobble. Check by rocking the lifted tire at 12 and 6 o'clock.

Control arms

Not steering parts strictly, but on coil-sprung solid-axle Rams the control arms locate the axle front-to-back and set caster. Worn bushings or the wrong arm length after a lift can affect how the truck tracks. Learn more on the lifted-truck page.

Actual alignment specs vary by model and year. Get them from your service manual or an alignment shop that knows lifted trucks.

Replacing or upgrading parts

Dodge Off Road's steering section covers linkages, box braces, stabilizer hardware and track bars for many Ram generations. Their install guides page has installation PDFs for many of their parts. It's worth a read before you buy, so you know what's involved.
