Solution

1. Fluid Inspection and Replacement

Sub-steps:
1. Open the hood and locate the power steering fluid reservoir.
2. Check the fluid level against the dipstick or markings on the reservoir.
3. If the fluid is low, top it up with the manufacturer-recommended power steering fluid.
4. If the fluid is dark or contaminated, drain it and replace it with fresh fluid.

2. CV Joint Inspection and Replacement

Sub-steps:
1. Lift the front of the vehicle using a jack and secure it with jack stands.
2. Remove the wheel to access the CV joint.
3. Inspect the CV boot for tears or leaks. If damaged, replace the CV joint.
4. To replace, remove the axle nut and disconnect the joint from the transmission.
5. Install the new CV joint and reassemble, tightening the axle nut to 50 ft-lbs.

3. Wheel Bearing Inspection and Replacement

Sub-steps:
1. With the vehicle still lifted, grab the wheel and check for play by moving it side to side.
2. If play is detected, remove the wheel and brake assembly.
3. Extract the wheel bearing by removing the retaining clips and using a bearing puller.
4. Install the new bearing, ensuring it is seated properly and reassemble components.

4. Tie Rod End and Ball Joint Inspection

Sub-steps:
1. Inspect the tie rod ends for any signs of wear or damage.
2. If worn, remove the cotter pin and nut securing the tie rod end and replace it.
3. Repeat the inspection for the ball joint; if worn, remove the lower control arm and replace the ball joint.
