Rotating Lugs on Son28 Thru Axle model

[Marc40a]

Hi guys,

Anyone else having the issue of the contact lugs rotating slightly as you're riding and pulling at the wire?

 I've really been clamping down on my thru axle tension and it's reduced the rotation somewhat but after a heavy trail riding the lugs are still moving a little bit after a few hours.

I'm wondering if the axle handle is getting knock by brush, but I really don't think it is.

Anyone else experienced this?
