Rack and pinion steering is one of two kinds of steering systems. When a rack and pinion assembly wears out, the steering feel and quality will decline. To prevent this from happening, you must replace your rack-and-pinion steering gear right away when it wears out.

When it’s time to buy a replacement rack-and-pinion steering gear for your vehicle, you should know what to do to make sure you get the right one. Read on to learn all about the rack-and-pinion steering gear, when to replace it, how much it can cost you, and more.

What Is a Rack and Pinion?

The term “rack and pinion” describes the basic design of this type of steering gear. The rack-and-pinion steering gear is newer, lighter, and takes less space than a conventional steering gear.

The rack and pinion can be hydraulically assisted, electrically assisted, or unassisted.

The rack and pinion can be hydraulically assisted, electrically assisted, or unassisted. When the steering wheel is turned, the steering gear pushes or pulls the wheels in the desired direction.

This rack-and-pinion steering system uses a pinion gear at the end of the steering column that’s turning against a geared rack. The steering column turns in time with the steering wheel, which also causes the pinion to turn. The pinion gear engages with the rack and moves the rack accordingly.

How Does a Rack-and-Pinion Steering Gear Work?

The rack connects directly to the tie rod in the steering linkage to move the linkage back and forth in a straight line. The steering gear input shaft is splined to the steering shaft U-joint. At the end of the steering gear input shaft, which extends into the rack housing, is the pinion gear. Two ball bearings reduce friction between the shaft and the steering gear housing.

Most rack-and-pinion units use a small metal tube that runs along the housing’s exterior to connect the two boots and transfer air from one to the other. If there were no means for air displacement between the boots, they can collapse as they expand or explode when they compress.

Internal threads on each end of the rack keep the externally threaded tie rods secure. A rubber boot at each side of the steering gear housing covers the end of the rack and the inner tie rod end to prevent dirt, water, and other contaminants from entering the assembly. Band clamps fasten the ends of the boots to the housing and tie rods.

The tie rods move back and forth with the rack. They also connect it to the wheels through the steering linkage. The housing generally bolts to either a flange on the firewall or to the subframe or engine cradle. The mounting points have rubber cushions to isolate the steering gear from shock and vibration.

What Are the Symptoms of a Bad Rack and Pinion?

Experiencing steering-related problems on your vehicle? They might be telltale signs of bad rack-and-pinion steering gears. Here are some of the symptoms you need to watch out for to help tell if your rack and pinion is bad:

  • Power steering fluid leaks
  • Odd noises when turning the steering wheel
  • Difficulty steering at low speeds
  • Loose sensation when turning the wheel
  • Wandering steering

A leak in your rack and pinion steering system is especially troubling. Leaks can indicate internal damage to the system, requiring a new or remanufactured replacement.

Can You Drive With a Damaged Rack-And-Pinion Steering Gear?

You can drive with a damaged rack-and-pinion steering gear, but it’s best that you don’t. Although a damaged rack and pinion won’t necessarily stop your vehicle from functioning, it would make it hard to handle or drive, which is unsafe. Additionally, driving with a damaged part can cause wear on the other parts of your vehicle’s steering system.

How Often Do Steering Racks Need to Be Replaced?

Like any other car part, the steering rack can eventually fail from normal wear and tear. If your vehicle’s rack-and-pinion steering gear starts showing signs of wear, replace it right away.

How Much Does a Rack and Pinion Replacement Cost?

An aftermarket rack and pinion replacement will typically cost you anywhere from $100 to $500 on parts alone. The price of a new rack-and-pinion steering gear depends on various factors, like the part’s brand, quantity, condition, operation, and your vehicle’s specifications.

Because an internal fluid leak usually requires you to replace the entire steering system, the cost to repair a rack and pinion leak is the same. While rebuilding the rack is an option, it requires highly specialized tools and knowhow. Rebuilding a steering system simply isn’t feasible for the average joe.

You can generally expect to pay around an extra $300 to $1000 to have your damaged rack-and-pinion steering gear professionally replaced. Of course, this is only an estimate and prices might vary depending on the rates in your area.
