Whaddya know, pulls to the nearside!

Newby chappie here. Seeking some answers to the perennial problems. The ol' gal (52 reg) seems to have developed a pull to the left, kind of over time but I reckon I'm just imagining the worst so I don't think it's bushes (am I in denial?). Just when driving not braking. Seems to be camber sensitive with a more pronounced pull where the camber is greater.

All ppl I speak with say it's the tracking...I thought tracking affected both wheels evenly because it is the toe-in, toe-out setting that is measured between the same points on the opposite rims. Therefore whether the tracking is right or wrong the only effect would be adverse (but equal accross the two tyres) tyre wear.

Anyhoo, as I'm just a numpty - anyone got any ideas before I commit myself and the motah to a scruinty event. Forearmed is forewarned an' all that. Ta everso.:confused:
