Granite What are these bearings for?

[Simon]

Hi all,

Just finished swapping out the bearings in my Granite 3S BLX with these.

I am pretty sure I changed out everything but there are 4 left.

The metal shielded one has a flange on it.

Can anyone tell me what these are for or have they just provided bearings I didn't need?

Thanks,

Simon

Flange bearing is for the slipper clutch

2 small ones are for the inside of the diff or could be for your steering block if you haven’t changed those out yet (can’t tell from the size from the picture)

The large one is used for the driveshaft which the granite doesn’t use.

Cool makes sense.

Didn't do the slipper clutch and made the decision not to open the diff. I did do the steering block which were slightly larger ones.

Is it worth proactively swapping those in, particularly the diff since it is totally sealed? or just when they fail?

Personally, I don’t bother changing the diff bearings since they are sealed.

The smallest inner diff bearings are the least needed bearings as they are sealed in silicon oil. They also don’t really do much most of the time. They are only used when the diff outputs have a bias.
