Solution

1. Preparation

Gather tools and parts necessary for the repair.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to prevent any electrical issues.

2. Inspect and Replace CV Joints

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Remove the front wheels to access the CV joints.
3. Inspect the CV joint boots for tears or leaks; replace if necessary.
4. If the CV joints are damaged, remove the axle by unbolting the axle nut and detaching the joint from the transmission.
5. Install the new CV joint and reattach the axle to the transmission, torqueing the axle nut to the manufacturer's specifications (usually around 180-220 ft-lbs).

3. Check and Replace Steering Components

Sub-steps:
1. Check the tie rod ends and ball joints for wear; replace any damaged components.
2. If necessary, remove the old tie rod ends or ball joints by unbolting them from the steering knuckle.
3. Install new tie rod ends or ball joints and torque the bolts to the specified torque (typically around 30-50 ft-lbs).
4. Reassemble any disassembled components and ensure everything is tightened correctly.

4. Test Power Steering System

Sub-steps:
1. Check the power steering fluid level; add fluid if low.
2. If the fluid is contaminated, flush the power steering system and replace with new fluid.
3. Start the engine and turn the steering wheel side to side to bleed any air from the system.
