Don't know how much you know about the columns so will assume zero.
Was the outer column just about screwed all the way in?
The screwing in and out adjusts the end float of the inner column (BM182) against its thrust washer (BM41) so a small amount of play up and down pulling on the steering wheel could be detected.....but this may be difficult due to heavy grease in the box.
Turning the wheel will cause a force by the worm on the steering worm wheel (BM32) which will push the inner column up or down.
It may be that the outer column was not screwed in far enough and end float set up when fitted so as you say it is too far out (therefore longer) and causing locking of steering wheel as it touches outer. Or maybe too thick a thrust washer was fitted or an extra thrust washer put in to take up wear so giving same problem of outer column too far out of box.
Also similarly has someone fitted a longer outer, cut down but not quite far enough giving same too long symptom.
Has the steering wheel nut been tightened with too much force in the past so pushing the steering wheel splines down into the end of the inner column....the bit just after where splines stop and inner column diameter starts so that wheel is now against outer column when nut done up?
Depending on all above factors there is not very much movement with in and out screwing of outer between too far in or too far out.
The worm is a push fit over splines on the inner....an interference fit.
