3. If fluid is dirty or contaminated, drain and replace it. Use a fluid siphon or turkey baster for removal.
4. Refill with the correct power steering fluid and replace the cap securely.

3. Inspect and Replace Damaged Steering Components

Sub-steps:
1. Use a jack to lift the front of the vehicle and secure it with jack stands.
2. Inspect the tie rods and ball joints for any signs of wear or damage.
3. If damaged, remove the old components using a socket set and replace them with new ones, torquing to manufacturer specifications.
4. Recheck the alignment of the steering wheel after replacement.

4. Check and Replace CV Joints

Sub-steps:
1. Remove the wheel to gain access to the CV joint.
2. Inspect the CV boot for any tears or leaks; replace the joint if damaged.
3. If replacement is necessary, remove the axle nut and disconnect the CV joint from the hub.
4. Install the new CV joint and tighten the axle nut to the specified torque value.

5. Verify Wheel Bearing Condition

Sub-steps:
1. Rotate the wheel and listen for any grinding noise indicating worn bearings.
2. If noise is present, remove the wheel and inspect the bearing for play.
3. Replace the wheel bearing if necessary by removing the hub assembly and pressing out the old bearing.
