I've tried lots of things to eliminate the 1x4 technic thin liftarm, but nothing
seems to work as well. Any suggestions are welcome.

At a guess, you need the arm to be central in a 1 stud width of axle.
A technique used by someone else (Mark Bellis I think) is to get a half
smooth technic bush (4265c) and cut it in half (length ways). This will
help keep the bar centred.

Thanks Dean!  I don't know why I didn't try this before.  I used a full with
bush and in conjunction with 4263 and it works very smooth.

I'll update the instructions to use the new configuration.
