Solution

1. Preparation

Gather the necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Allow the engine to cool before starting work.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Drain Power Steering Fluid

Place a drain pan under the power steering fluid reservoir.
Remove the cap and use a siphon pump or turkey baster to drain fluid from the reservoir.
Dispose of the old fluid according to local regulations.

3. Remove the Steering Rack

Raise the front of the vehicle using a jack and secure it with jack stands.
Remove the front wheels for better access to the steering components.
Disconnect the steering shaft from the steering rack by unbolting the universal joint connection.
Unbolt the steering rack from its mounting points on the subframe.
Disconnect the power steering hoses from the rack, capturing any residual fluid in a drain pan.
Carefully slide the steering rack out from under the vehicle.

4. Inspect and Replace Seals

Inspect the seals at the ends of the steering rack for signs of wear or damage.
If damaged, remove the old seals using a seal puller or flat screwdriver.
Clean the area and install new seals, ensuring they are seated properly.

5. Reinstall the Steering Rack

Reinsert the steering rack into position under the vehicle.
Reconnect the power steering hoses and ensure they are torqued to manufacturer specifications.
Reattach the steering shaft to the steering rack.
Secure the steering rack to the subframe with bolts, tightening them to the specified torque.

6. Refill Power Steering Fluid

Refill the power steering reservoir with new fluid, ensuring it meets Toyota specifications (typically ATF or specific power steering fluid).
Start the engine and turn the steering wheel side to side to purge air from the system.
