- Check the power steering fluid level in the reservoir.
- If it's low, add more fluid of the recommended type.
2. Air in the power steering system:
- Air can get into the power steering system when a hose or line is disconnected or a seal is broken.
- This can cause the fluid to bubble and foam.
- To remove air from the system, you may need to bleed it by following the manufacturer's instructions.
3. Faulty power steering pump:
- A faulty power steering pump can cause the fluid to bubble and foam.
- If the pump is damaged or worn out, it may not be able to generate enough pressure to circulate the fluid properly.
- You may need to replace the power steering pump if it's faulty.
4. Clogged power steering filter or line:
- A clogged power steering filter or line can restrict the flow of fluid, causing it to bubble and foam.
- Check the filter and lines for any blockages and clean or replace them if necessary.
5. Faulty power steering rack:
- A faulty power steering rack can also cause the fluid to bubble and foam.
- If the rack is damaged or worn out, it may not be able to properly control the flow of fluid.
- You may need to replace the power steering rack if it's faulty.
If you're not comfortable performing any of these checks or repairs yourself, it's best to take your vehicle to a qualified mechanic for diagnosis and repair.
