Solution

1. Preparation

Gather tools: jack, jack stands, socket set, torque wrench, pry bar, and inspection mirror.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Raise the Vehicle

Use a jack to lift the front end of the RAV4 and secure it with jack stands.
Ensure the vehicle is stable before proceeding.

3. Inspect and Replace Worn Components

A. Inspect Suspension Components

Visually check the struts, shocks, ball joints, tie rods, and sway bar links.
Look for any visible wear or damage.

B. Replace Worn Ball Joints

Remove the wheel using a socket set.
Disconnect the ball joint from the control arm using a ball joint separator.
Install the new ball joint and torque to manufacturer specifications (usually around 50-70 ft-lbs).

C. Replace Sway Bar Links

Remove the nuts securing the sway bar links to the sway bar and control arm.
Install new sway bar links and ensure proper torque (generally 30-50 ft-lbs).

D. Check CV Joints

If damaged, remove the axle from the CV joint and replace the entire axle assembly if necessary.
Ensure the new axle is properly seated and torque the axle nut to manufacturer's specifications (typically around 150-180 ft-lbs).

4. Reassemble and Lower Vehicle

Reinstall the wheel and lower the vehicle.
Tighten wheel lug nuts to the specified torque (usually 75-85 ft-lbs).
