Thanks for the help guy - to be honest I'm still kinda confused!
But looking around the net a bit it seems I need either a tie rod, and tie rod end or both (can't find track rod ends, so I'm assuming tie rod is a differnt name for the same thing?!) - but both together are only like £15 - so I'll just get that and hope for the best!
and that vagcat.com just confused me more! ha ha, but thanks anyway!
