Solution

1. Preparation

Gather all necessary tools and parts. Ensure the car is parked on a level surface and the ignition is off.
Tools Required: Jack and jack stands, socket set, torque wrench, steering wheel puller, and alignment tools.

2. Inspect and Replace Worn Components

Tie Rod Ends & Ball Joints:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Remove the front wheels for better access.
3. Inspect the tie rod ends for play by pulling them side to side. If excessive movement is noted, replace them.
4. Similarly, check the ball joints for wear. If they exhibit play or damage, replace them.
Steering Rack:
1. Inspect the steering rack for signs of wear, including any visible play or leaks.
2. If the steering rack is faulty, disconnect the steering linkage and remove it according to the manufacturer's specifications.
3. Install the new steering rack and connect all necessary linkages, ensuring all bolts are tightened to the specified torque.

3. Align the Wheels

After replacing any components, perform a wheel alignment to ensure proper steering response and tire wear.
Use alignment tools to adjust camber, caster, and toe settings according to manufacturer specifications.
