Slip yokes, or a sliding shaft would be an issue. It would have to be sealed completely as a little bit of dirt/mud would add too much resistance. The better design would be to have the pivot points perfectly aligned so the shaft didn't need to change it's length. CV joints have the shaft slippage inside the boot, but then the boot is subject to damage.Originally Posted by kghills
Here is a chart giving U joint life expectancy at different angles. Now say a joint will go 200,000 miles, even 10% of that is pretty good. Add to that the low spped of an AATV. 15 degrees each way gives you 30 degrees total. Off road truck guys will commonly run 30 degrees you will find. Depending on how you design everything to pivot will determin if you need a slip yoke or not. The Avenger I pictured earlier does not use one.

U-joints are very durable and less prone to damage from sticks etc........I'd build with U-joints. Unless you went way high with the horsepower, it would be easy to build the shafts yourself with limited access to machine tools.
