At some point last year, my rear drive shaft boot started detaching at the rear of the swing arm. It detaches, I reposition, ride a few hundred miles then it detaches. The bike is a 2016 with 57K on the clock.
Granted, it was likely triggered because I did not fully seat the driveshaft after my first inspection of the splines (that 1/4 inch makes a difference), but at the rear drive side there is a “hard” plastic frame around the lip. It has some flex, but it’s intended to keep the boot tabs firmly pressed against the rear drive housing. Without it, very little tension is needed for the boot to pop off. I’d say this plastic frame has cracked, so it no longer maintains tension. Sadly, replacement is the only option. No way to fix it. Whether you can confirm this without completely removing the boot and inspecting it under good lighting is another issue. It took me a while to discover the source of my problem when it happened to me.
