ok from the start, i have been getting vibration through my steering wheel, so i took wheels off and noticed excesive wear on the inside of both tyres so i took it to national where i got the tracking done when i got new tyres. but they have said its not the tracking coz its sitting fine and its not the wheel balance, but the said it could be that the KPI (king pin incline, i think) needs ajusting because its sitting toe-in quite bad and only vauxhall could do it. but i went to vauxhall and they said they dont have the equipment to do it, so ive been round all the garages and nobody can do it, some have never heard of it.
the suspention set up has never been touched as they thought it might of been that.
so what can i do to fix the problem, ( put in new suspention? i have no idea) its a mk4 astra 2.2
