Bearings

[rampagemt]

I got my dune runner stripped and the bearings are only a couple months old as I just got in June. I have never cleaned bearings before and wonder if its time to clean them. How often do you guys clean or replace your bearings. Sorry if its a dumb question but I am so confused and don't want to put bearings back in if they should be cleaned. Thanks in advance

If the bearings feel crunchy, they need to be cleaned or replaced. If they're rubber sealed, you can clean them. If they're metal shielded, not so much. If the bearings feel good, but the seals are dirty, just wipe them down.

Here's a bearing maintenance vid...

What could I use to substitute bearing oil?
