I'll start with a story:

Starting about a week after I got my FF G6A bearing wheels, they started to pop off after I seshed. The reason that they came off is because the bearing rubbed against the bolt, causing it to unscrew. I figured it was a problem with my Bollie Trucks, that the part that the wheel hangs on (that comes off of the hanger) was too short or something. About two weeks after that, the bolt started to tighten as well as pop off. I wasn't able to screw the bolt on very far, or the wheels wouldn't spin properly. This caused the bolts to pop off even more frequently. Then, today, I realized the bearings in the wheels were somewhat farther out than they should be. I pulled the wheel against the bolt to get the bearing back in place. I'm figuring this was the cause of all those problems. But as I sesh, they tend to come slightly out of place again. I'm wondering if this is a normal problem for FF wheels, or are they just mine?

normal with every wheel company

apart from nocomply lol
i use double sided tape on the nut, instantly does the job...
you can use glue as well

If you bring a trick down to hard it can make the wheels loose

just buy some autoblocks, well worth it.
