My 87 has an issue with the steering wheel - it's a TT type, when fully out you can't lock the steering wheel (SW) in position. The position lock works on a cam or key that sticks out of the inner shaft - this key rides in a slot machined down the inside of the main outer shaft. The shafts are locked together at any SW height by screwing a bolt down on a central rod which tensions the key up into the slot which binds and locks them in position. But when apart mine has the slot - but at the top the slot is deeper, hence when the SW is fully out, the cam can't lock because the slot is too deep - there is not enough available movement in the locking lever on the SW to lock in all positions. It looks like the slot has a (possibly S'steel ) insert that takes the wear and tear - but does not come all the way to the top of the slot (key way). It has not slipped down or anything. It just looks like it was a mistake and made short.
Has anyone taken one apart, seen what I'm describing or know anything that could help me. Thanks.
