Steel ball bearings.

Hi all,

 

Looking through my bz222 build manual, its got steel balls to go in the diff. Would ceramic/another material make a good upgrade to go in from the start? Or are the steel balls good enough?

Ceramic balls are a good upgrade, as they're durable and even smoother than steel

 

Why not use the steel until you score the diff washers and then change them when you rebuild?

Cheers FIMS. Sounds like a good plan. Wasn't sure how much of an upgrade it'd be, or if it was an easy win etc.

I think Tungsten Carbide balls are better than Ceramic as they are not as brittle and less likey to fail. but material aside its the quality of the balls that matters. you can get ceramic balls very cheap but unless they are all accurate in size you wont benifit at all from using good steel balls. I would say for the buggy you got the steel balls will be fine to begin, it's more important to get the plates run in nicely. so dont overtighten when you first build or the balls can dimple the plates, run with just enough pressure then gradually tighten after each few runs making sure its not slipping. I would say bit of an art building ball diffs but i do enjoy getting my diffs silky smooth. also make sure to use the thin grease that looks like vaseline.

Yeah tc are good too, I found they scored my washers pretty quick,  I probably overtightened it
