Today I took the Slingshot to Champion Power Sports in Athens, Al where I purchased. Had to be there before 2:00 pm because they don't run diagnostics beyond two pm. They took it into the shop and ten minutes later brought it out and had me ready to roll. They verified what I had found stated in OP above. They filed warranty request for steering rack replacement. They also stated that I may have to bring it back in for tear down to file pics with Polaris as part of the verification process. Wonder if they would settle for a video previously taken...
On a side note... FYI...
While I had the boot peeled back from the steering rack carrier to tie rod, I grease packed the steering shaft. I turned the wheel all the way to the right, greased the large shaft, then turned the wheel full left to pull the grease in. Straightened the wheel and wiped off excessive grease. This eliminated the annoying rattle. Don't know for how long, but can't hurt my situation.
Door open @Tripod, @Bill Martin, @Mr. Clean.... play nice and safe for work!
