That's good one
I don't think so, not unless they moved the steering rack as well, best thing to do in found someone there who knows something about the mechanics of a motor vehicle, the dipstick you have spoken to clearly doesn't have clue.
Well you may laugh ....
My steering was spot on central ...
Had tyres changed (nothing else) and then steering was off centre.
Only lasted for a while and gradually reverted to being central again.
Maybe due to tyres 'bedding in' or suspension extended while wheels off ?
Come to think of it, couple of problems i've fixed for people.
Cars pulling one way or another for no obvious reason..
Swap the tyres about and all then ok... weird :)
So, don't be too hasty to pick holes - odd things happen
