Wobbly center shaft....

[KyoshoK]

Hi

i have a problem with the center shaft being a little too wobbly for my liking... wobbles for like 3mm and touches the servo ears.

i have put about 1mm fuel tube (o-ring) on either end of the shaft to keep it snug and cushioned.

i thought my centre shaft may of been bent so i changed the shaft to new one. also have changed the large bearing on the spur.

i have a center one way and front diff setup.

it looks like the play is coming from the centre one way. it wobbles a bit too much

any ideas?
