P11 primera steering pump pulley wobble help

[p11primgt]

My p11 gt steering pump pulley has a quite severe wobble,whats the cause of it,is it the pump itself or the pulley on the pump, your please

Doe's it throw a belt?
Doe's the power steering still work?
Doe's it whine?

The bearing could be bad, it's probably time for a new pump + flush.

It makes a sight noise on tick over,the belt do move about but not come off the pulley,steering pulls to left last few days,last two months pull to the right,all suspension parts new !

Also just when i notice the wobble on the pulley/pump/the top up bottle had leak some fuild on the top of it,i dont know how ?
