Solution

1. Preparation

Gather necessary tools and parts for the repair.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the battery to prevent any electrical issues during repair.

2. Lift the Vehicle

Use a jack to lift the front of the vehicle securely.
Place jack stands under the vehicle for safety.

3. Remove Wheels

Remove the front wheels using a socket wrench to gain access to the steering linkage.
Store the lug nuts in a safe location.

4. Inspect Steering Components

Check the tie rod ends for wear; replace if there is excessive play or damage.
Inspect the rack and pinion assembly for leaks or damage.
Examine the steering knuckle and associated joints for any signs of wear.

5. Replace Damaged Components

If components are worn, remove the old parts using a socket set.
Install new tie rod ends or steering linkage components, ensuring they are torqued to manufacturer specifications (typically around 44-65 ft-lbs for tie rods).
Reattach any bolts or fasteners, ensuring they are secure.

6. Reassemble and Lower the Vehicle

Reinstall the front wheels and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and remove the jack.
Torque the lug nuts to the manufacturer's specification (usually about 76-80 ft-lbs for Highlander).
