Noises problem
2004 Ford C-Max 6 cyl Two Wheel Drive Manual 41000 miles

Ford Focus Cmax 2004 - 1.6 petrol - 41000 miles.

When steering lightly or full lock when reversing or in gears 1 & 2 i can here a groaning,creaking noise coming from front wheels. Almost like something needs a good oiling. It seems to appear in winter and disappear in summer?? I have had Power Steering checked professionally & no problem can be found. Only problem we have just been told about is the front tyres are badly worn on inner wall which need replacing & tracking is out. Could this be cause of noise or something else?? I have had so many different mechanic's tell me different reasons for the noise,i am confused!!Please help
