Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and is securely lifted using jack stands.
Disconnect the battery before starting work on any electrical components.

2. Inspect Suspension Components

Tools Required: Socket set, torque wrench, pry bar
Remove the wheel to access the suspension components.
Visually inspect struts and shocks for any signs of leakage or physical damage.
Use a pry bar to check for play in bushings and joints.
Tighten any loose bolts to manufacturer specifications.

3. Examine Drivetrain Components

Tools Required: Socket set, torque wrench
Remove the wheel to access the drivetrain components.
Inspect the CV joints for tears or play; look for grease leakage.
Check the axles for any damage or excessive play.
If damaged, replace CV joints or axles as necessary.

4. Replace Worn Components

Tools Required: Socket set, torque wrench, possibly a puller for stubborn parts
For any worn or damaged parts identified in previous steps, proceed with replacement.
Follow manufacturer specifications for torque settings on all fasteners.
Reassemble components in the reverse order of disassembly.
