how to fix a stiff steering wheel in my Toyota Corolla E170 (2013-2019)

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the ignition is off.
• Disconnect the negative battery terminal to prevent electrical shorts.

2. Check and Replace Power Steering Fluid

• Locate the power steering fluid reservoir.
• Clean the cap area to prevent contamination during opening.
• Remove the cap and check the fluid level; it should be between the "MIN" and "MAX" marks.
• If fluid is low, add the appropriate type of power steering fluid (refer to owner's manual).
• If fluid is dirty or contaminated, proceed to drain and replace it:
  1. Place a drain pan under the power steering fluid return line.
  2. Disconnect the return line and let the old fluid drain completely.
  3. Reconnect the line and fill the reservoir with fresh power steering fluid.
  4. Turn the steering wheel from lock to lock to purge air from the system.

3. Inspect and Replace Power Steering Pump (if necessary)

• Remove any covers obstructing access to the power steering pump.
• Disconnect the pump's electrical connector and fluid lines.
• Remove the mounting bolts using a socket set.
• Install the new power steering pump by reversing the removal steps and torqueing bolts to the manufacturer’s specifications.

4. Inspect Steering Rack and Column

• Visually inspect the steering rack and column for any signs of wear or damage.
• If any damage is found, replace the steering rack assembly.
• Reinstall any covers that were removed during inspection.
