Yep. What way does the steering wheel sit? Down to the left or right? You can try the 'magic spanner' approach i call it haha. Adjust the track rod ends about 1 turn at a time, to bring the steering into centre. So if the wheel sits down to the left say then shorten the OS track rod by a turn or so and see if the wheel comes into the centre. Or just take it to a place which has a proper machine like a hofmann. Also make sure nothing is worn like lower arm bushes, ball joints, track rods etc.
