Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the 12V battery to prevent electrical issues during repair.

2. Check Power Steering Fluid

Tools Required: Fluid siphon, clean rag
Inspect the power steering reservoir for fluid level. If low, top off with the recommended fluid type (Tesla OEM fluid).
If the fluid is contaminated, replace it by siphoning out the old fluid and refilling it with new fluid.

3. Inspect and Replace Steering Components

Tools Required: Socket set, torque wrench, pry bar
Remove the front wheels for better access to the steering components.
Inspect the tie rod ends and control arms for any signs of wear. If damaged, replace them (ensure to torque new components to the manufacturer’s specifications).
- Sub-steps:
  - Use a pry bar to check for play in the joints.
  - Remove the cotter pins and nuts from the tie rod ends, then detach them from the steering knuckle.
  - Install new tie rod ends and torque nuts to specification.

4. Inspect Steering Rack

Tools Required: Socket set, torque wrench, jack stands
Inspect the steering rack for any signs of leakage or damage.
If necessary, replace the steering rack by disconnecting it from the steering column and suspension components.
- Sub-steps:
  - Disconnect the power steering lines (be cautious of fluid spillage).
  - Remove the bolts securing the rack to its mounts.
  - Install the new steering rack and torque the bolts to specification.
