Dave,

I suggest you take it back and ask that the alignment be done again - and ask them why they didn't check pressures.

Ive found they have varied between 30 - 50 psi on the wifes 100 after having new tyres and wheel alignment????
how do they do it?

Mrs Diamond replied:

thats whats called a caster adjustment lol.
if they cant work out why its pulling just adjust air pressure.

Yes Mr Diamond is right. In my travels to workshops I was told by a few Alignment places that if they couldnt sort it out they would pump air into a tyre to make it look like the car was fixed. Very sad but true. Funny thing was, they even tried this trick on my old GQ. Not realising that just a few months earlier they told me all about this "short cut" as they called it. I can tell you they were not happy when I told them to fix right or expect public notification in the local paper, and im not talking small shops here, these are some big named truck and 4wd alignment places.
I must point out that this was a few years ago but am sad to hear that it is still happening.
