2016 Force 800 EPS.  Started making a clicking/clunking sound when the acceleerator is pressed in reverse or forward, but only under load.  I jacked it up and ran it in reverse, low, high, 4x4 and no noises.  You can push it or spin the wheels, no noises.  When it is on the  ground and you take off it makes the noise, once you are at speed, it stops making the noise. 
I tried to identify where its coming from, dont think its coming from the rear as much as the center of the vehicle.  Could a belt casue this behavior?  Bad clutch?
Thanks for the help!

The first thing I would check would be all the CV joints, then the U-joints on the front drive line as well as that carrier bearing. After that and sense I had some plastics off anyway I would pop the CVT cover and inspect the belt for lost cogs or belt separation....as that can cause that type of noise too.

Differential or CV joint. Check the axles first, then pull the actuator and start checking parts.
