I have a square shaft on the front of one of my rigs and have had no problems at all. It does run a mini case so nose cone trouble.

On my '74 FJ40 I run a schedule 40 shaft and it purrs along smooth as can be at any speed.

I think the most important part is how straight it is assembled. My square shaft runs very smooth and I have no qualms about spinning it higher than 30 MPH...

There is a good square shaft write-up in the Toy-mini FAQs on PBB. You can also find a write-up about a trueing jig for assembling Toyota shafts while you are there...
