What is a steering gearbox?

The steering gearbox is the older and more heavy duty type of steering gear, and may be power steering, or manual steering. When the steering wheel is turned, the steering gear, whether power assisted or not, turns the pitman arm, which causes the wheels to turn.

How does the steering gearbox work?

The steering wheel is connected to the steering gear by the steering column. When the steering wheel is turned, the steering gear will turn the pitman arm, the link between the center link and the steering gear. The pitman arm and idler arm, which connects the other side of the center link to the chassis, hold the steering linkage up, and allow it to move to either side with the pitman arm. When the steering linkage moves to one side, the wheels turn in that direction, causing the vehicle to turn.

What are the symptoms related to a bad steering gearbox?

Power steering gearbox leaks and mechanical issues are evident as soon as the vehicle is moved, and power steering fluid on the ground is accompanied by strange noises and a different steering feel. Besides leaking oil, the power steering pump might being sounding overworked when turning normally as the steering gearbox begins to increase required input pressure before turning the wheels. Lastly, the steering gear may make a clunking noise, and the steering wheel would feel loose. When the mounting bolts break, or stretch, the steering gear will be permitted to move back and forth, which will also create noticeable wear marks on the mounting area.

Can I drive with a steering gearbox problem?

Power steering component failure almost always means a leak, but the amount of leaking fluid will determine if the vehicle can be driven. Also, if failure of the pulley or accessory belt occurs, the vehicle may be stranded if the belt also drives other accessories. Small leaks will not prevent the vehicle from driving, but when fluid cannot be added quickly enough to keep the pump full, a tow truck is recommended to avoid damaging the fuel pump and steering gear.

How often do steering gearboxes need to be replaced?

For most vehicles, the power steering system will last well over 100,000 miles before any failures occur. Mechanical failures and leaks in the power steering system are considered usually avoidable if maintenance has been performed according to the manufacturer service intervals. Keeping the power steering fluid fresh, and the system free of contaminants is the key to ensuring long power steering system life. As any system that carries high pressure will, the system will eventually fail from normal wear and tear, but this should be well into the serviceable life of the vehicle.
