Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and securely lifted using jack stands.

2. Inspect and Replace Tie Rods

Sub-steps:
1. Remove the front wheels using a socket set.
2. Locate the outer tie rod ends; check for any play by moving them up and down.
3. If worn, use a tie rod removal tool to disconnect the tie rod from the steering knuckle.
4. Install the new tie rod end and torque it to the manufacturer's specifications (typically around 45-55 Nm).
5. Repeat for the inner tie rod if necessary.

3. Check and Replace Ball Joints

Sub-steps:
1. Remove the wheel and inspect the ball joints for wear.
2. If the ball joint is loose, use a ball joint separator tool to remove it from the control arm.
3. Install the new ball joint and secure it with the appropriate fasteners, torquing to specifications (usually around 50-70 Nm).

4. Inspect Steering Rack

Sub-steps:
1. Check for leaks around the steering rack; if fluid is present, the steering rack may need replacement.
2. If replacing, disconnect the steering column from the rack and remove any mounting bolts.
3. Install the new steering rack, ensuring all connections are secure and torqued accordingly.

5. Alignment and Test Drive

Sub-steps:
1. After making any replacements, perform a wheel alignment to ensure proper tracking.
2. Test drive the vehicle to assess the steering feel and confirm repairs.
