Anybody knows where this rubber bushing came from?

Anybody a idea where this rubber bushing came from?
Just took the center diff out and this fell down. The small white rubber bushing

It might have come out of one of the drive cups. O rings or bushings are often used inside the drive cups to remove slop from the driveshafts.

it goes in the drive cup 100%

Most likely

Yes thank you! without it there's a lot of slop indeed!

I changed them for Arrma ones. Had to cut them shorter to fit. Otherwise there is no slack in the drive shafts.

 

[rdevalk]

Should there be one in every cup? because I only have one! with the driveshaft from center diff to rear it was on center diff side.

Just 1. If you put 2 there is no slack anymore

 

[rdevalk]

Yes but there's only one at the driveshaft from center to rear. From center to front there's none. is that a problem?
And I don't see them on the Corally site to purchase

it's just a slice of silicon fuel hose I believe.

Thats normal. It is just a slice of fuel hose

If there's enough room, one in the front diff input cup would be my choice.
With the slightly downwards angle of the diff, and the height of the diff cup, a small o-ring in the cup just stopped the shaft from fouling the edge of the cup and groove.
But make sure there's still enough float, otherwise the shaft might get bent as the chassis flexes.
