Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety.
Lift the vehicle using a jack and secure it with jack stands.

2. Inspect and Replace Power Steering Fluid

Tools Needed: Fluid pump, clean funnel
Check the power steering fluid reservoir for proper level and contamination.
If fluid is low or dirty, remove the reservoir cap, pump out old fluid, and refill with manufacturer-recommended power steering fluid.

3. Inspect and Replace Damaged CV Joints

Tools Needed: Socket set, torque wrench, pry bar
Remove the wheel to access the CV joint.
Inspect the CV boot for tears or leaks; replace if necessary.
If the joint is damaged, remove the axle nut and disconnect the CV joint from the hub. Replace with a new CV joint or axle assembly as needed.

4. Replace Worn Tie Rods or Ball Joints

Tools Needed: Ball joint separator, socket set, torque wrench
Inspect tie rods and ball joints for wear.
If found worn, remove the cotter pin and nut, then use a ball joint separator to detach the joint from the control arm or steering knuckle.
Install the new tie rod or ball joint, tightening to manufacturer torque specifications.

5. Check and Replace Wheel Bearings (if necessary)

Tools Needed: Bearing puller, socket set, torque wrench
Remove the wheel and brake assembly to access the hub.
Inspect the wheel bearings for play; if they are worn, use a bearing puller to remove them.
Install new bearings and reassemble the hub, ensuring proper torque specifications.
