What is causing a cogging on the wheel?

[AizenSousuke]

One wheel started not moving at times\takes some force to move. I took out the diff and cleared the sand and it moves freely after that. Today the issue came back on the same right side rear wheel.

I also found some circular items on the shafts on both rear wheel:

Do they come from the bearings?

Looks like you're going bearing shopping. imo

drats...

Is this a good option? Not sure what is sealed vs non-sealed though

 

[N.Mango]

sealed is definitely what you want.

Yep, looks familiar. Bearing cover.
I use sealed bearings for all exposed bearings. Only for the bearings inside the diff housing and motor I use non sealed (less friction, and not exposed to sand).
Turn the wheels by hand from time to time, especially if you run a lot in sand or wet conditions. When you hear a crunchy sound it‘s time to replace them.

Sand. RC's most fun enemy.

Fast Eddy bearings are just as good as Jim's Bearings. Same with TRB Bearings. They are all about the same til you get into ceramic vs regular bearings.

TRBRC has awesome Customer service.
No matter the brand, every so often you may get a missing BB or even get a bad one. It just happens. TRBRC is on point in this regard. Usually my go to brand.
But all 3 brands are great, as @Kla912000 stated above! Even Avid is great.
Many go to Jims Bearings for their Motor BB's.
Choose your own poison.

Personally....leave ceramics to the racers. You have no need for that. Wait most of us here is in need of this and that and those and that other thing.

I have not found fasteddys with the option for hubs only or for HR hubs

Don't worry guys I won't be going on the ceramics because I cannot afford them anyway LOL
