Problem: rear binding slipping out of place
My rear factory binding frequently slips out of place, and it is becoming tedious to constantly fix. It usually moves after landing a jump, flatland maneuvers, or any other time where hard, fast shock is applied. The front used to have this problem, but for some strange reason, it stopped happening.
Previously, whenever my binding became loose and moved on the hill, I would use a screwdriver I brought with me to loosen the screws, readjust, and tighten again. After I took off the binding, I noticed that there was water underneath. This was probably from loosening and tightening the screws on the hill, but the front binding was the same (it had water underneath), so I wiped off the water and cleaned with Windex.
In addition to the water problem, my bindings have seriously scratched the topsheet of my board. I think this is from the hard rotation that occurs when they slip out of place after a hard shock. I've tried tightening the screws so that they are pretty tight, but it doesn't seem to help much. I also removed the entire binding and examined the baseplate and footbed teeth to see if they were stripped; they weren't.
What do you think is the problem? Any suggestions for how to fix?
