Power steering whine.

[daume]

I have an '01 986 (non turbo). Ive had it for almost two years and its allways had a whining noise associated with the power steering. Its loudest at idle while turning the steering wheel but its allways present at low rpm's. I have checked the fluid level, it appears to be fine. Has anyone else experienced the same problem and what did they find as a solution? Im hoping to find out that its just a high pressure line vibrating or maybe there is a conditioner I can add to the fluid. Or if it needs a new pump maybe someone has a suggestion on where to get mine remaufacturered instead of buying new. Im new to the forum, thank you everyone in advance for any help.

UPDATE; After doing some google research I have found BMW owners and Mustang owners with the same problem claiming its a result of air in the system. Any Ideas?
