Steering Racks

Steering Racks

Rack-and-pinion steering is quickly becoming the most common type of steering on cars, small trucks and SUVs. It is a simple mechanism. A rack-and-pinion gearset is enclosed in a metal tube, with each end of the rack protruding from the tube. A rod, called a tie rod, connects to each end of the rack.

The pinion gear is attached to the steering shaft. When you turn the steering wheel, the gear spins, moving the rack. The tie rod at each end of the rack connects to the steering arm.

Maintenance

Failure? There are several reasons why the rack and pinion fail.

• tears and punctures on the seals attached to the steering rack, the system will not produce the same fluid pressure which will consequently cause fluid leaks, loose steering and/or hard steering.
• lack of maintenance. Fluids can become contaminated, making it difficult for the fluid to transfer through hoses, which in turn causes the system to work harder.
• Failure of the power steering pump. Normal wear and tear can cause the rack and pinion to break.

Needs to be replaced?

• Several signs will occur when the steering rack needs to be replaced.
• One of the signs is a whining noise when turning at a standstill.
• Another sign is difficulty with steering at lower speeds.
• When driving on the highway, loose steering and shaking on the steering wheel are signs of a bad rack. Badly worn tires are another sign.
• A noticeable fluid leak (power steering fluid) is also a sign of replacement.

Time to replace?

It is highly recommended to have a professional technician perform the replacement. Unfortunately, there are not any other alternative repairs for a bad rack and pinion. Proper tools, skills and knowledge are necessary.
