Hi ,
Today Morning I got some noise when i try to turn after driving 10 km i found it so loudly and hard to turn. what it could be pump or hose leak? please advice. Can I use any Power steering fluid or must use volvo and why?
thanx

 

The fluid level might just be low.
You will need to use synthetic Steering fluid.That is what Volvo uses/Reccomends.

Sometimes the hose will leak at the bottom of the fluid bottle.
