- Replace any seals or the entire rack if damaged.
- Reassemble all components and ensure all bolts are torqued to the manufacturer's specifications.

3. Refill Power Steering Fluid

Locate the power steering fluid reservoir.
Fill the reservoir with the recommended type of power steering fluid.
Start the engine and turn the steering wheel from lock to lock to circulate the fluid.
Check the fluid level again and add more if necessary.
