Could it be the power steering pump? Cause it is leaking a bit from one of the hoses and there is a small bit of play in the pulley. Do I have to Bleed the power steering? It's too hard to hear exactly where the noise is coming from because it's so loud but it's either the power steering or something in the balancer.
Thanks for the help
It could be the power steering pump.
Does it turn hard by hand?
Another possibility is the idler pulley bearing.
Check that out too while the belt is off.
