if the car is aligned and the wheel is still not straight look down on the floor board were steering shaft exits the cabin. Remove the pincher bolt then follow the shaft up towards the steering wheel till you reach a bracket with two bolts remove those. Follow the shaft up higher and remove the final two bolts to get to these you might have to remove the fuse cover or some of the lower steering covering. The steering wheel shaft assembly will then pull out. The shaft is splined at the bottom so just pull it out and turn it till it is straight and put everything back together.
