Hi alfamoment, sorry to hear you're having the same kinda trouble as me, though hopefully the uk garages will go easier on you than over here. It only whines, or should i say squeals, when the temp is -1 or colder and goes away after 30 seconds. My tie rod end is gone on the passenger side, so when i lock hard to the left and reverse, the wheel appears to groan loudly and acts as though it's slipping on the road.
I really can't believe that so many people are having issues with their steering racks and no official recall has been made. I think it's shocking that the factory can put the wrong grade p/s fluid into the car and expect the customer to pay 1200 euros PLUS vat for a part after 50k. and i'm an alfa fan having upgraded from a 156. Will be looking forward to your reply. I would suggest if you can, jack the car up on both sides and look for play in the wheels. If you find any, which i suspect you will, take care not to kerb the wheels or hit potholes till you get her seen to. all the best!!
