[Steering & Suspension] Sqealing in full lock

[Squad]

Hi there,
Every time I put the steering wheel on full lock left and right and I have a sqealing sound, the power steering fluid is full and I have no idea what it might be and would be most grateful if  anyone has any ideas as what it might be.

sounds like your alternator/power steering pump belt is loose

Hi - check the auxiliary belt sounds like it is worn/shiny and slipping when you load the pump. If not the belt then one of the pulleys may be miss behaving but I'd go for the belt first
