A bad rack and pinion can be a nuisance to drive around with, but it can also be dangerous. It can affect your ability to control the vehicle as well as handle difficult driving scenarios such as taking a turn or driving in rain or snow.
Rack and pinion systems are found in cars and trucks of all types, and if they fail, they can cause a lot of damage.

Before that Lets Learn about rack and pinion steering Function
The steering rack is a part of your car’s suspension system. It serves as a bridge between your steering box and the pitman arm. The steering gear box is made up of two main parts, the column shaft, and the rack gear case.
The steering gear box is responsible for your ability to turn your wheels. It transmits power from the steering wheel to the tie rod ends and then by way of axle shafts to the wheels.
When replacing your steering gear box, you will want to inspect its condition carefully. As with any auto part, you will want to know if it is in good working order before installing it in your car.
Rack and pinion steering problems
A worn-out or faulty rack and pinion can cause many different problems depending upon where these gears are failing.
Here are the things you should look for to help recognize problems with your rack and pinion system:
1. Loose steering
Loose steering is probably the most common symptom of a bad rack and pinion setup. You might notice it as a vague or uneven feel to your steering wheel. Sometimes the wheel will even shake while driving.
2. Steering wheel shakes
This symptom points to problems with the rack and pinion assembly itself. Wheel shakes are often accompanied by clunking noises coming from under the front end of your vehicle.
3. Clunking noise
This noise indicates that something is rubbing against something else, like a bad CV joint. It’s possible for the clunking noise to be caused by loose components in the steering rack itself, but more likely, it’s caused by parts in the suspension system rubbing against each other (e.g., ball joints).
4. Wheels don’t return to the center
If you notice that the wheels on your vehicle continue to point in one direction even after you’ve taken your hands off of the steering wheel, then this could be a sign that something’s wrong with your power steering.
5. Excess slack
Excess slack is a condition that occurs when there is an excessive amount of play in the steering wheel. When this happens, it can cause the vehicle to jerk and weave when you turn.
6. Looseness in the steering wheel
is another symptom that you could have a bad rack and pinion. When you feel looseness in your steering wheel, it could be due to the fact that your rack and pinion has become worn down or damaged.
This can make it very difficult for you to drive your car, as it will be hard for you to control it properly on the road.
7. Vehicular instability
on the highway is yet another symptom that you could have a bad rack and pinion. This occurs when your car begins to swerve from side to side while driving at high speeds.
It can also cause your car to pull either toward one side or toward the center of the road while driving straight. These symptoms can be caused by problems with your tires or suspension system, although they could also be due to problems with your rack and pinion.
The rack and pinion system also tends to be more durable than worm gear systems; however, there are some disadvantages to this type of steering mechanism.
You can prevent further damage by finding and fixing the problem as soon as possible.
How do I know if my steering rack needs replacing?
When your steering rack is leaking power steering fluid, your best bet is to get it replaced. Driving a vehicle with a leaking steering rack is one of the most dangerous situations that you can find yourself in.
If you have noticed that your steering wheel shakes when driving at lower speeds, this could be an indication that your steering rack is in need of replacement. It’s important to note that loose steering and shaking on the steering wheel are not the only signs of a bad rack.
Badly worn tires are another sign that you may need to replace your steering rack. A bad rack will cause your tires to wear faster than they normally would. You may be able to see this by looking at the shoulder of your tires or by noticing any uneven wear on them.
When you hear grinding noises from underneath the hood, this could be another sign that it’s time for a new rack and pinion unit.
Lastly, if you notice fluid leaking from underneath the vehicle, this could also mean that it needs a new steering rack unit. The fluid leaking from under the vehicle could be power steering fluid or some other type of fluid depending on what kind of vehicle you drive.
The disadvantage
The first disadvantage is that there are moving parts in the steering mechanism of a car with a rack and pinion system. This means that you may need to change a seal on occasion or replace a gear if it’s damaged.
Another disadvantage to this type of steering mechanism is that it can leak a little bit of fluid from time to time, especially if it has been damaged in an accident.
However, almost all modern vehicles use the rack and pinion system because it’s more responsive and durable than other systems were in years past.
The downside of rack and pinion systems is that they can be noisy at times, especially if there are any problems with the bearings or shafts involved in the operation of the system.
The points where these moving parts meet can also wear out over time depending on how much you drive your car. You should pay close attention to the noises your car makes when you turn corners in order to catch these problems before they become too serious.
How do I know if my rack and pinion or power steering pump is bad?
A leak around the power steering fluid reservoir is also a sign that your rack is going bad.
If the power steering fluid is leaking, there is probably a leak in the rack (or the fluid reservoir). Even if there isn’t a leak, replacing the fluid is recommended at 100,000 miles or every five years (whichever comes first) because this service will flush out dirt, debris, and contaminants from your power steering system.
This isn’t necessarily an emergency — you have time to order one and have it shipped to your mechanic before replacing the rack. But if you see an actual hole in the line or the fluid level is dropping quickly, get it replaced right away.
