Solution

1. Preparation

Gather tools and materials: socket set, torque wrench, OBD-II scanner, steering fluid, alignment tools.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to avoid any electrical issues.

2. Inspect and Replace Power Steering Fluid

Remove the power steering reservoir cap.
Check the fluid level; if low, add the recommended power steering fluid type.
If the fluid is discolored or contaminated, drain and replace it:
1. Locate the power steering pump and disconnect the return hose.
2. Drain the old fluid into a suitable container.
3. Reconnect the hose and refill the reservoir with new fluid.
4. Start the engine and turn the steering wheel from lock to lock to purge air.

3. Check and Replace Steering Components

Inspect tie rods and ball joints for play:
1. Lift the front of the vehicle using a jack and secure with jack stands.
2. Grab the tie rod and wiggle it; any movement indicates wear.
3. If worn, remove the cotter pin, nut, and disconnect the tie rod from the steering knuckle.
4. Install new tie rods and secure with the appropriate torque specification (usually around 30-50 ft-lbs).

4. Wheel Alignment

After replacing components, perform a wheel alignment:
1. Use alignment tools to measure and adjust camber, caster, and toe settings according to manufacturer specifications.
2. Make adjustments to the tie rods as necessary to achieve proper alignment values.
