Solution

1. Preparation

Tools Required: Jack and jack stands, tire iron, socket set, torque wrench, wrench set, and possibly a spring compressor.
Ensure the vehicle is on a flat surface and the parking brake is engaged.
Disconnect the battery to prevent any electrical issues while working on the vehicle.

2. Lift the Vehicle

Use the jack to lift the rear or front of the RAV4 depending on which shock absorber is leaking.
Securely place jack stands under the vehicle to ensure stability.
Remove the wheel for better access to the shock absorber.

3. Remove the Shock Absorber

Locate the upper and lower mounting bolts of the shock absorber.
Use the socket set to remove the upper mounting bolt first, then the lower mounting bolt.
Carefully pull the shock absorber out of its mounting position, noting any washers or spacers that may fall out.

4. Replace the Shock Absorber

Compare the old shock absorber with the new one to ensure they match.
Insert the new shock absorber into the mounting position.
Reinstall the lower mounting bolt first, followed by the upper mounting bolt.
Torque the bolts to the manufacturer's specifications (typically around 45-60 ft-lbs for upper and lower bolts, but verify in the service manual).

5. Reassemble and Test

Reattach the wheel and lower the vehicle back to the ground.
Reconnect the battery.
Test the vehicle by pushing down on the rear or front to check for proper shock absorption.
