Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Use jack stands to elevate the vehicle safely.

2. Inspect and Replace Worn Components

A. Steering Components

Remove the front wheels using a socket set.
Inspect tie rods and ball joints for play or damage.
If any components are worn, replace them as follows:
- Tie Rods: Remove the cotter pin, nut, and disconnect the tie rod from the steering knuckle. Install the new tie rod and secure it with the nut and cotter pin.
- Ball Joints: Remove the retaining bolts, disconnect from the control arm, and replace with a new ball joint, securing it with the specified torque (usually around 50-70 ft-lbs).

B. Suspension Components

Check for the condition of the shock absorbers and bushings.
If the shocks are leaking or damaged, replace them:
- Remove the upper and lower mounting bolts, detach the old shock, and install the new shock absorber, tightening the bolts to the manufacturer's torque specifications.

3. CV Joint Inspection

Inspect CV boots for tears or leaks.
If damaged, replace the CV joint by:
- Removing the wheel and brake assembly, then detach the CV axle from the transmission and steering knuckle.
- Install a new CV axle, ensuring proper alignment and securing it with the necessary hardware.
