Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery (if working on electrical components).

2. Inspect and Replace CV Joints

Tools Required: Socket set, torque wrench, jack and jack stands
Raise the front of the vehicle and secure with jack stands.
Remove the wheel for access to the CV joint.
Inspect the CV joint boot for tears or leaks. If damaged, proceed to replace it.
To replace the CV joint:
1. Remove the retaining clip from the joint.
2. Disconnect the joint from the wheel hub by removing the axle nut.
3. Slide the old CV joint off the axle and replace it with a new one, ensuring it is properly seated.
4. Reinstall the axle nut and secure with the specified torque value (usually around 150 Nm).
5. Reattach the wheel and lower the vehicle.

3. Inspect and Replace Suspension Components

Tools Required: Socket set, torque wrench, pry bar
Examine control arms, bushings, and sway bar links for wear.
If any components are found defective:
1. Remove the old parts by unbolting them from their mounts.
2. Install new components, ensuring all fasteners are torqued to the manufacturer's specifications.
3. Recheck alignment after replacing suspension parts.

4. Check Steering Components

Tools Required: Socket set, torque wrench
Inspect the steering rack and tie rods:
1. Check for play by moving the steering wheel with the vehicle stationary.
2. If play is detected, replace the tie rod ends or steering rack as necessary.
3. Ensure all connections are tight and torque to manufacturer specifications.
