Hi All, I have a ford galaxy 2002/52reg 1.9 tdi auto,turning steering left to right has a creaky sound and vibration. If i turn the steering wheel slightly left to right the vibration sound goes. Ihave checked the alternator pulley by taking the tension off and it free wheels anti-clockwise. My alternator is a bosch 120amp. Am i checking the alternator pulley correctly? Could it be the power steering pump? Any suggestions Many Thanks in advance. Iam based in south east not scotland...........
