How to Replace the Steering Box on a Chevy
Replacing the steering box is a complicated repair. Before you begin this maintenance, it is important that you understand how to perform the replacement. Many Chevy vehicles have a steering box instead of a pinion-type steering system. This is especially true for older Chevy models. This article will provide a step-by-step guide to replace the Chevy steering box.
Gather Your Tools
The first step is to make sure that you have everything that is needed to complete the repair. To replace the steering box, you will need a socket set, torque wrench, tie rod puller, liquid wrench, hydraulic fluid, drain container, car jack, jack stands, parking brake block, and the new steering box.
Jack Up the Car
The next step is to jack up the car. To do this, use the car jack to raise one corner of the vehicle. Place a jack stand underneath, and then rest the car on it. It is very important that you do not rest the car on the jack, which is not stable. A jack stand will provide a secure lift to the vehicle. Once the car is jacked up, place brake blocks behind the rear tires to prevent the car from moving.
Disconnect the negative battery cable. This is the black cable attached to the battery. This will remove the power system from the Chevy.
Drain Steering Box
Drain out the hydraulic fluid from the steering box before you remove it. Place a drain bucket underneath the box and then disconnect the hydraulic fluid hose. This will allow it to drain.
Disconnect Pitman Arm
The next step is to disconnect the Pitman arm. You will need to use the tie rod puller to disconnect it. It will normally be somewhat difficult to remove.
Disconnect Steering Box
You are now ready to remove the steering box. First, disconnect the steering shaft from the steering box. Then you will need to loosen and remove all of the bolts that are holding the steering box onto the frame.
Install New Steering Box
Installing the new box is the same process as disconnecting the old one, but in reverse. First, mount the new steering box on the frame and tighten all of the bolts. This will hold it in place. Then you want to connect the steering shaft. Once the steering shaft is connected, you will need to reconnect the Pitman arm. This can be difficult to connect. Be aware that you may have to use force.
Reconnect Hydraulic Fluid Hose
Now that the steering box has been installed, you want to reconnect the fluid hose. This is what will provide hydraulic fluid to the power steering system.
Refill Hydraulic Fluid
The next step is to add hydraulic fluid back to the power steering reservoir. You want to fill it to the fill line. Make sure that you check for leaks. You want to make sure that nothing is leaking, or you could be left without steering. The hydraulic fluid hose is the most likely site of a leak.
Reconnect Battery and Lower Car
Reconnect the negative battery cable and then lower the car. Before you drive the car, turn the steering wheel all the way to both the left and the right several times. Then recheck the hydraulic fluid level to make sure it is still full.
You should follow this procedure to replace the Chevy steering box. This is a complicated repair, but it can be performed in about an hour by following this step-by-step guide. Performing the repair yourself will save you an enormous sum over taking it to a mechanic to do the job. You will still have to purchase the new steering box and repair components, but this will generally be cheaper than buying from a mechanic. In addition, you will not have to pay the labor costs.
