What is a sector shaft on steering box?
What is a sector shaft on steering box?
The sector shaft is a critical component of an automotive power assisted recirculating ball steering gear and one that is vulnerable to fracture due to loads transmitted through the steering linkage under certain conditions.
How does the steering shaft connect to the gear box?
One of those parts is the intermediate steering shaft. It connects the steering wheel with your steering gear box or the rack and pinion in your vehicle. The intermediate steering shaft has what’s called a universal joint on one end which is what allows the shaft to connect to the gear box.
How does an intermediate steering shaft connect to the steering wheel?
The intermediate steering shaft has what’s called a universal joint on one end which is what allows the shaft to connect to the gear box. The other end connects to a second universal joint and that is attached to your steering wheel. Basically, the steering shaft is a piece of metal that is an angle connecting the gearbox to the steering wheel.
How to identify your steering gear box-Lee power steering?
This gearbox was found in GM trucks and SUV’s up to 1986. It is easy to identify because it mounts on the outside of the frame and the mounting tabs are on the opposite side of the gearbox. Notice how the mounting holes are on the top side of the gearbox. The one variable with the 708 gearbox is that it came with two different sector shafts.
Why is the steering gear not on center?
Most pitman shafts are indexed with 4 large spline gaps. When the spline gaps line up with the axis of the steering box, its on center. If they aren’t lined up, it’s not on center. Furthermore, when at center the flat on the input shaft will be at top-dead-center.

When do you need to replace the steering shaft?
In a steering system, the steering shaft connects the steering gear box to the steering column. The shaft eventually corrodes. When it begins to fail, it’s common to hear popping sounds or clunking noises as you turn the wheel. If it becomes more difficult to turn, it’s time to replace the shaft sin
