Can a rack and pinion be removed and replaced?
The rack and pinion assembly is not a simple bolt on that you can remove and replace without paying attention to some details. The assembly itself is made up of gears that come together to steer the vehicle when you turn the steering wheel.
How does the rack and pinion work on a car?
The steering column turns when you turn the steering wheel, causing the pinion also to turn. The pinion gear engages with the rack and moves the rack in the direction and amount required to make the turn you desire. Steering can be either power or manual, with most last-model cars (since the mid-70s) having power steering.
What causes a rack and pinion to leak?
Excessive play in the steering wheel is one of the major giveaways of a worn rack and pinion assembly, whether it’s a power or manual unit. Hydraulic units can also leak, either internally increasing the resistance to your steering input or externally splattering fluid all over your car and driveway.
Do you have to disconnect power steering when replacing rack and pinion?
Because of this, it will have fluid traveling to it in order to make the turning of the gears easier. When you replace the rack and pinion you will have to disconnect the hoses from the power steering. Reconnecting the hoses will need to be done without cracking it, or causing any other leaks.

Disconnect the steering joint between the steering column and rack and pinion assembly. Do not allow the column or wheel to turn while the joint is disconnected. The image above shows a steering universal coupler on the left and a rag joint on the right. I’m pointing to what is called a pinch bolt in the image on the left.

Where does the steering column go in rack and pinion?
There is a seal where your steering column enters the rack and pinion assembly, then a seal where each tie rod attaches. Each of these seals have to keep high-pressure power steering fluid contained while allowing the steering column to rotate and the tie rods to move as well.
