I have to remove a panel below the seat to access the power beyond line to replace it. The panel seems easy to remove but I'm having trouble with removing the two knobs. One is the 3pt lowering speed and the upper one is the suspension adjustment knob. I don't see any type of set screw holding them on (but my eyesight isn't what it used to be) and have oiled them to hopefully help in the removal. I've tried pulling off by hand with no success. I am just curious if anyone has done this, my next step will be tapping with a hammer but I really don't want to break them.
