Hi , well today I took the steering wheel off again to see if I had put it on slightly out of line. I did put it on slightly wrong. I didn't line up the markers on the colomn and steering wheel hence wasn't straight . There are 2 locating studs on a plastic part under the steering wheel but fixed to the column but this moves around by an inch so these are no good to use as a guide to keep the wheel straight. I was only out by 2 or 3 lines on the shaft of the colomn but boy was it annoying not having the wheel totally straight. Any way all straight now and attached are a couple of photos of the plastic studs and the markers on the wheel and colomn.
