I've only ran about 10 battery packs through my Kraton. I'm getting annoyed at having to replace front inner wheel bearings. So far I have had to replace the left side once, and the right side twice. It's obviously something that needs to be addressed. Can anyone recommend any fix or mods for this? Bearing suggestions would be appreciated too. I didn't use ARRMA original bearings to replace the Shattered bearings. I used standard, blue rubber sealed bearings and they still Shattered.
