I asked if it was at a Vauxhall dealer as there are ongoing reworks to do with steering and they would of checked them.

I am at a disadvantage in not being able to test the car but the first thing to do would be to ascertain if it was pulling or drifting on the road camber, this can be done by driving on a quiet road with a camber on each side and a high crown in the middle, a normal car will follow camber on the left side of the road and drift to the left and when driven on the wrong side (the right) it will drift to the right camber then driving evenly on the crown it will go straight.

The Meriva has a high centre of gravity and do suffer from camber drift, it is like driving along the side of a hill , gravity has an effect.

If it is found to be pulling the tyres would be checked, they should all be the same make and tread depth, then the tracking camber and castor would be checked and adjusted on a laser alignment geometry test.

If the dealer has done all of this then have a second alignment test at reputable steering/tyre centre.

I hope this helps, best regards, Vauxdoc.

This is why the last paragraph suggests that you go to a specialist alignment centre, I know only too well that main dealers do not want to spend too much time on this type of work , you should have an independent test especially as you have tyre wear, this proves something is amiss !!!

Thank you for using Just Answer.
