My boots keep scrunching up I take the axle out and its fine,put it back in and couple rotations and it does the same thing.There has to be a simple solution the clamps are tight and they have not twisted

 

If the boots are thin and flimsy compared to the oem Polaris boots,install the drive shafts,loosen the clamps turn the drive shafts a couple revolutions and see if the boots position them selves correctly.Then you should be able to tighten the clamps.

 

I installed the one factory shaft and the other shaft is not collapsing the boot as badly.I have pictures of the collapsed boots and will be calling eastlake tommorrow

Like OPT said, boot isn't on the axle properly. If the large end is positioned properly in the groove (CV) then the smaller end (axle) isn't far enough out.

 

I rode all day sunday and it did not fail but is still slightly collapsed
