172 pulling to the left?

[Windy172cup]

Hello, For bout 3 weeks now my 172cup's been pulling to the left. Had the tracking and 4 wheel aliment done. Its been in to a few garages and no one can find a problem. Also there's a slight banging/chinging noise from the front right? Is that to do with the pulling? Thanks (will be signing up probley next week)

Checked the tyre pressures and changed the tyres front to back. Nothing!
