If you're experiencing power steering problems, it's unlikely to be due to air in the lines. The problem is more likely related to:
* Low power steering fluid: Check and top off the fluid reservoir if necessary.
* Faulty power steering pump: This is a common cause of power steering issues.
* Leaking power steering hose or rack: Look for leaks around the hoses and steering rack.
* Faulty power steering rack and pinion: This can be a more complex issue.
Before attempting any repairs yourself, consult your owner's manual or a qualified mechanic. Improperly working on a power steering system can be dangerous.
