Consider this:
 
1. When the nose gear leg is first installed, the bearings = blocks are=20 positioned between the engine mount plates and clamped so the gear is = plumb and=20 swings properly into the wheel well.
 
2. Two holes are then drilled thru each bearing block to=20 ultimately secure them to the engine mount and pass thru the spacing = tube=20 (carefully cut to length to not make the bearing blocks so tight as to=20 bind).
 
3. The bearing blocks should have been marked as to left/right, = inside/outside and top/bottom.  Since each block is drilled in = place, they=20 are unique to each airplane and to their location/position on that=20 airplane.  The two holes may be spaced equally apart but if the = blocks are=20 rotated, transposed or swapped, it is almost a guarantee that the leg = will not=20 be plumb or retract correctly.  There is only one way to be correct = but at=20 least five ways to be wrong - it isn't 50/50.
 
So, before the nose gear leg is removed for service make sure = the=20 blocks are marked so they can be replaced exactly back from whence they = came and=20 in the same orientation.
 
If your leg was taken off, it would have been possible that the = blocks=20 did not go back to the proper place.
 
This is the kind of problem that can occur when the builder is = no=20 longer servicing the airplane.
 
 
 
That is very good information, of which could easily be missed = while=20 trouble shooting nose gear problems.
