How do u stop bearings loosening?

[kurt warren]

yeh alot of the time my bearings come loose, NOT MY AXLES. is there a way to stop this happening or fix this? i want it to stop because it makes my scoot rattle

 

[Billie Rainbow]

ok so its not ovalised but it moves? mine do that and i have ocd with any scooter of mine i.e has to be perfect, you can fix it by filing down spacers to a point that tightens the bearings to only just slow them down or basically pushing the bearings in so they dont freespin as easily but doesnt affect the performance of them. also make sure you have spare spacers just incase

Yah file down the bearing spacers or take them out. If thats not the problem, put a washer on the axle.

or get eagle spacers, they worked so well. at least for me...

p.s. Im not sure if they work well or make a difference with plastic cores but they are almost definatley a neccessity if you have metalcores.
