Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and secure using wheel chocks.
Lift the front of the vehicle using a jack and secure with jack stands.

2. Inspect and Replace Worn Components

a. Steering Rack

Inspect: Check the steering rack for leaks and play.
Replace (if necessary):
1. Disconnect the battery.
2. Remove the steering column cover.
3. Disconnect the steering shaft from the rack.
4. Disconnect power steering lines (be prepared for fluid spillage).
5. Unbolt the steering rack from the subframe and remove it.
6. Install the new steering rack and reverse the removal steps.

b. Tie Rod Ends

Inspect: Check for excessive play or damage.
Replace (if necessary):
1. Remove the wheel to access the tie rod end.
2. Use a tie rod puller to detach the tie rod from the steering knuckle.
3. Remove the lock nut and unscrew the tie rod from the steering rack.
4. Install the new tie rod, adjusting to the same length as the old one, and secure it with the lock nut.

c. Ball Joints and Control Arms

Inspect: Look for wear or play in the ball joints and control arms.
Replace (if necessary):
1. Remove the wheel and disconnect the ball joint from the control arm.
2. Unbolt the control arm from the subframe.
3. Install the new control arm and secure it in reverse order.

3. Alignment Adjustment

After replacing components, take the vehicle to a professional alignment shop to ensure proper alignment settings.
