Default Bearing guide

Pic for attention:



I'm hoping that together we can figure out a guide to bearings depending on terrain, driving style and power.
What kind would be suitable, how often we would need to change them, if grease is desirable and what kind then, different bearings for axles, pinions, transfer case etc.

Fx.
Driving style:
Heavy bashing, speed runs, light bashing
Terrain:
Mud, rocks, gravel, hydroplaning on water, dusty roads
Power:
4s, 6s, 8s

Two kinds we might start with making guidelines might be the heavy basher that runs in mud and rocks on 8s, which is probably the most demanding use for the vehicle.

On the other hand we might have what maybe most people do, a light basher that mostly runs on dusty roads on 4s and never let's his vehicle touch water.

These 2 vehicles would need a vastly different maintenance schedule.

What would you recommend?

I have been running AVID bearings in all my trucks for years with no complaints. They all get dirty and eventually wear out. Get a quality bearing, stay on top of maintenance, and all is good. Even with a strict maintenance schedule I still get bit with a failure now and then. It's part of the game.

Steve, how is that rear dust cover holding up? Where can I get one/find one or something similar to it?

Im trying out fast eddy ceramics, if they dont last long, I'll pick up some boca ceramics.

Last 2 months have been rain and flooding so no testing. The shield is just a CHEAP plastic plug that comes in automotive parts we get that cap holes. Radiators, a/c parts and such. I am sure you should be able to find a supplier on the net for these.

Totally forgot you've been having a ton of rain. Im sitting in 105-110 degree weather so I'm also stuck inside. Lol.

What is that plug out of? Or do you have some dimensions on it?

GO HERE search part number t-15 and it will give you the cup measurements. You will have to trim to fit. Simple lexan scissors.
It doesn't have to be this exact size. As long as it will cover the pinion like a cup on top of it and deflect the dirt it will work.

If you are bashing in mud and wet conditions, are ceramic bearings worth it? Wouldn't you have to change them out just as often as the steel ones?
With different replacement schedules it would make sense to then have steel bearings in the front bulkhead, front axles and rear axles and ceramics in the trannie, rear diff and then have the rear pinion bearings with 2 ceramic bearings and one steel bearing that would be replaced more often?

Don't do wet stuff (rc anyway) so I don't know. I use regular 1 dollar bearings from AVID except trans and motor where I use ceramics. Years ago when I first got into rc I got sucked into the ceramic for everything and found out they are not always needed for everything.

It seems like if you're doing mud/water stuff you're best buying cheaper bearings that you won't be so reluctant to replace. I can't imagine a $20 bearing fighting the affects of mud and water for much longer than a $1 one so better to save the money and have plenty of extras.

Have you tried using bushings? I would think it could be smart to use bushings on the axles and maybe on the rear pinion, not sure though.

I think I'll go ceramics on the better protected parts, but steel bearings in other places with some marine grease.
