Thats the thing it looks normal the only way u would know is if u drove it,its going to the right when the hands are off the steering wheel.Theirs no cosmetic damage.

have you had a wheel alignment? now it sounds like you could weld up the crack and get an alignment and it will be ok?

Guys how long after rego has run out before u need a blue slip,is it 3 months.

Get a wheelie and they will be able to tell you if there's more wrong

fwiw on cars with adjustable castor rods, a 'token' few mm of adjustment can make the difference between 'straight as an arrow' and 'changing lanes without indicating' when you let go of the steering wheel momentarily.

If you hit 'anything' hard enough you can bend or alter things easily enough to alter the steering 'neutrality' without it being massively visible damage.

This is by no means 'the last word' on things - but even though in std form, caster is non adjustable on the dattos, get them to measure the existing caster to see where it is at. In my experience caster tends to have the greatest effect on which way a car pulls. Second (not by much but still second) is toein/out which may not affect which side it will pull to (like caster differences will) but will tend to alter how severe the effect of a caster imbalance is. and camber, is more or less 3rd in line and less likely to have as big an efect on it.

I had the same problem. I got all the bushing up front replaced and a new set of tires
helped massively! almost unnoticeable pull now

Yeah pretty sure about it being 3 months. At least in NSW anyway. I've certainly utilised this time period to my benefit in the past.
