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.
