Steering rack rebuilding begins once the rack housing is completely clean. Discard the old materials to avoid confusion during the rebuilding process.

3) Lubricating The Rack Assembly

Applying chassis grease on the rack adds lubrication and prevents metal parts from rubbing. Spread a generous amount of chassis grease around the steering rack’s teeth and on its back.

These areas are prone to contact with the bearing when it rolls over the shaft. Prevent friction and overheating using the chassis grease. It protects your rack assembly from wearing down when used.

Next, put some chassis grease on the pinion or valve assembly. Use a Teflon seal to secure it on the rack teeth. Following the same principle with the rack, the housing is also prone to get damaged.

Ensure that the entire rack assembly has enough lubrication. It prolongs the lifespan of your steering mechanism.

4) Checking For Leaks

After rebuilding the rack assembly, it’s time to check for leaks. Run a dynamometer test to ensure the proper functioning of your new steering assembly. Ensure safety when installing it in your car.

The dynamometer test assesses the newly-assembled rack. Conduct a pressure effort test and check it by pushing and pulling the assembly. Doing so ensures that your rack has no problems.

Checking for leaks prevents reopening and fixing your steering rack. Your steering system should contain no leaks to avoid damage. A leaking rack drains its oil in the power steering housing.

In return, it damages your steering assembly and puts you back to square one. Ensure the absence of leaks and avoid unwanted repairs. Save money for maintenance by checking any leaks.

5) Installing The Tie Rod Ends

Reinstalling the tie rod ends comes next after checking for any leaks. It is an easy process for a trained mechanic. Ask for professional help when installing the tie rod ends.

Improper installation causes wheel misalignment. Your car veers to the other side without intentionally turning with the wrong installation. The tie rod ends should fit perfectly in the steering assembly.

Ensure the tightness of the pin into the spindle. Install the tie rod ends and checks for snugness. Each part should fit exactly right into its place.

The tie rods should fit snugly in the steering assembly. Loose tie rods affect your steering. Avoid this from happening by ensuring proper tie rod placement.

4 Preventing Damage On The Steering Rack

Steering rack rebuilding takes time. Damaging your steering assembly is an added expense. Thus, it’s necessary to prevent damage to the rack by avoiding factors that contribute to it.

1) Avoid Potholes

Driving your car is fun. Going top speed gives you the thrill of adrenaline gushing into your veins. However, mindless driving can damage your vehicle, especially its steering assembly.

A car’s steering system is composed of several pieces that work together. The steering process is possible if these components are in position. However, these are prone to damage if exposed to extreme force.

Potholes do more damage to your suspension and steering system. If your wheel hits a pothole, a sudden change in suspension from going up and down exerts force. It could damage the delicate components of your steering assembly.

Avoid potholes when driving fast. Higher velocity creates a strong impact when hitting a pothole. The higher force it cushions, the greater risk it faces.

The force exerted when hitting potholes could damage the tie rods and rack assembly. It makes your car out of control.

2) Align Your Wheels When Running Over Ramps At A Lower Speed

The same principle applies when running over potholes and ramps. However, an additional precaution needs attention. Align your wheels when running over ramps at a lower speed to avoid damaging your rack.

Approaching a ramp at an extreme steering angle puts your power steering assembly at risk. The force exerted during the bump when running over ramps radiates force towards the whole steering system.

It puts pressure on the joints that might damage the whole assembly. In return, the rack is at risk of getting damaged. Drive slow when passing over a ramp. Ensure that the wheels are in a neutral position.

3) Avoid Dry Steering

You may have heard that dry steering is not good for your car. Well, it is. And the reason is simple.

Dry steering your car exerts effort on the steering system to move. If you steer a moving vehicle, the force you exert is lesser. The wheels will follow the road’s thread and move without much effort.

However, dry steering in a stationary car forces your front wheels to move. The power steering system will try to go towards your intended direction even with resistance. The force preventing its movement transfers towards the steering assembly.

It puts your rack at risk of wearing out. Forcing a car’s wheels to turn while immobile also damages your tires. It’s better to avoid dry steering your vehicle and prevent damage to your steering assembly’s rack.

4) Proper Maintenance

Proper maintenance is necessary to prevent damage to your rack. Poor maintenance results in damaging your steering system. The need for scheduled maintenance prevents damage to your assembly.

The seals on the rack could leak anytime. Check its consistency and watch out for any damage. A leaking rack damages the inner components of your steering system.

Prevent this from happening by observing proper maintenance. The rack is responsible for maneuvering your car. If this gets damaged, it causes more harm.

5 Differentiating A Bad Steering Rack From Other Problems

A bad steering rack is not the root cause of your steering problems oftentimes. Differentiating a faulty steering rack from other problems needs careful assessment. Identify other factors that might affect your steering.

1) Tie Rods

Your car’s tie rod ends can cause steering problems. Faulty tie rods pull your car to one side or the other. The steering rack houses the tie rods making it hard to differentiate what causes bad steering.

Identifying the cause of steering problems is hard unless you conduct an actual visual check. Changing your tie rods every 75,000 – 100,000 mileage ensures they are in good shape.

Prevent steering problems and unwanted changing of your rack by inspecting the tie rods. Replacing them occasionally prevents steering problems. Good tie rods help you differentiate the cause of steering problems.

2) Wheel Alignment

Improper wheel alignment also causes steering problems. Checking your wheel alignment prevents your car from swerving. Wheel alignment is essential in differentiating the root cause of bad steering.

Problems with steering don’t necessarily mean changing your rack. Steering rack rebuilding consumes time and resources. Look into other possible causes like improper wheel alignment.
