I have the issue.Many of us have not had an issue with this. I’ve had the shocks on and off my EXe and my wife’s EXe multiple times to tune or service. Check the torque on the upper and lower bolts. I use 15Nm on both, but many seem to require 17Nm to secure theirs.
There is no play you can feel with your hand, but if I compress the shock a bunch of times and then apply side pressure on the shock/piggyback there is a "knack/creak" sound coming out from it.
I torqed the top bolts to 17 and the lower bolt to 15 and it still happens
