Sub-step 1: Inspect the tie rod ends and steering linkage.
- Use a socket set to remove any protective covers.
- Check for any excessive play by manually moving the components.
Sub-step 2: If play is detected, tighten or replace the tie rod ends as necessary.

- Reinstall any covers removed.

3. Check and Refill Power Steering Fluid

Sub-step 1: Locate the power steering fluid reservoir.
Sub-step 2: Inspect the fluid level; if low, add manufacturer-recommended power steering fluid.
