Thanks so much Malek. You are a wealth of knowledge.
I didn't realign my car because none of the arms were moved and the subframe came out as one single unit so I thought the alignment wouldn't be out of whack (assuming the subframe was put back properly - which I think now could have been done incorrectly (without markings or jig)).
I will align the car to see if everything is OK and if not I guess you would have to have a frame straightening machine to get everything back into place? Any other suggestions to check this?
Thanks again for all the help and information.
