Issues with assembly of mmu3 selector guide bars

So I'm assembling the mmu3 from scratch and I'm putting in the guide shafts for the selector slide and the slide works freely till I insert the lower bar and it starts to jam up on either end of travel  how can this be best resolved?

The selector slides fine until the lower bar is fully inserted into the final hole then it starts to bind up

Are you trying to do the Step 15-16? 

Is the shaft fully inserted - like all the way in as picture showed (third picture in Step 15)?

yes but i gave up on that for the moment cause it just looks like, under power it seems to move fine. myt idea of moving freely is a bit freer( like sliding with no force). It goes from left to right and tightens up a bit on the far ends of travel but not badly just more force needed to move it.

It can be a bit tight I found because it's not on bearings it's on brass tubes
