Reasons for Truck Steering Issues

Common Causes of Steering System Failures

The main reasons for part failure within the steering system of a truck can be due to several causes, such as:

• Contaminated fluid
• Improper fluid levels
• Broken belts
• Damaged steering pump
• Extensive use or force

Each of these causes can negatively affect part performance and cause damage or complete termination, resulting in costly repairs.

Contaminated fluid can cause fittings to lessen in material, clog the steering wheel system entirely, create increased friction, and cause pump damage as a result.

Improper fluid levels range from either too much or not enough fluid. Increased fluid amounts can cause the valves and seals to collapse due to pressure, and not enough fluid will result in a lack of ability for your truck to exert the allotted force needed to turn the vehicle.

Broken belts are caused by excessive stretching, fraying, corrosion, or breakage. Each of these origins will result in a failed steering system entirely.

A damaged steering pump is caused by unnecessary strain on the pump, which can cause failure prematurely.

The Importance of Maintenance

Although normal wear and tear are entirely normal, professionals recommend keeping an eye out on parts through routine maintenance. Expert technicians will know what to look for and share with the driver the signals that it is time for repair or replacement. That information makes the operator more knowledgeable and prevents unexpected failures in the future.

Professional technicians also recommend practicing safe driving when operating trucks. Aggressive driving can create a strain on the entire system and cause damage to some or all components of the steering system.

Components of the Steering System and Their Signs of Failure

Your steering system is composed of several parts, and a technician will inspect them to determine if the steering system is in working condition. These parts include:

Power Steering Pump

Releases pressure to the hydraulic fluid, which helps the operator to turn the truck. It may whine or grind during operation, specifically during a turn. The driver may experience tightness or slow response, and may notice reddish-brown liquid under the vehicle if the pump is leaking.

Steering Rack

Permits the wheels to rotate from either side when the steering wheel is turned. Excessive noise, movement, or fluid leaks indicate an issue. Cracked rubber, loose connections, or failed seals may also be visible.

Steering Coupler

Creates a guaranteed connection between the steering wheel and the steering rack. Made of rubber, it can lose elasticity over time. Symptoms include bind and locking, excessive vibration, difficulty steering, and failure to re-center the wheel.

Tie-Rod Ends

Connect the steering rack from the steering knuckle to the vehicle's suspension. Worn tie-rod ends may cause uneven tires, misaligned front end, steering wheel vibration, and clunking noises.

Power Steering Hoses

Connect the steering pump to the steering rack to push pressurized fluid. Cracking and internal wear or corroded fittings can lead to hose failure.

Final Thoughts

All of these failures result from either regular wear and tear or neglect. The steering rack, coupler, tie-rod ends, and power steering hoses must be monitored through routine maintenance. Regular maintenance allows the operator to catch minor issues before they stop operation completely.

It is highly recommended to keep up on all fluid levels and monitor the performance of parts by using visual and audible senses.
