ok i got a question about bearings?

how offten should you clean them? once a week once a month partial cleaning full cleaning?
how do you remove them? any speaical tools? i know some people use lube where do you get it well i think thats it lol thanks

In my opinion cleaning them would depend on how often you run the vehicle, where its run, and how dirty the area is. So what vehicle do you have? on or off road? I would use thin oil to lubricate such as 3 in one or tri flow teflon lube.
