Causes of Power Steering Pump Failure
There are several reasons why a Toyota Tacoma’s power steering pump might fail. One common cause is simply age and wear. Like all mechanical parts, pumps wear out over time, especially if the vehicle is used heavily or driven in harsh conditions.
Another significant cause is low or contaminated power steering fluid. If fluid levels are not maintained, the pump has to work harder, which increases wear and tear. Additionally, air bubbles in the fluid can lead to noise and erratic steering. Dirt or metal particles in the fluid can scratch the pump components and reduce efficiency.
Faulty belts are another major culprit. The serpentine belt drives the power steering pump, and if it becomes loose, cracked, or worn, the pump cannot function correctly. This problem often causes squealing noises and poor steering response. Finally, improper installation or using the wrong parts can also lead to early pump failure. Some replacement pumps are not built to the exact specifications, which can shorten their lifespan.
