Positional issues, sorry if this is a repost.
(OP)
My problem is this,
I have 2 bushings aligned to each other with a shaft running through their centers. when I measure on the CMM It's telling me the back bushing is out of position to the front bushing but they are bored on the same axis. I've indicated my chuck and it's running perfect. The back bushing call out is Dia. 0.05M E(which is front bushing)M B(which is a perpendicular flange) see below for my lame sketch.

Any help would be great guys.

Mint - Not likely. if there is deflection I would see that in the form of a taper would I not?

If this is the case and you are using the smallest bust to datum from (E) then this may indicate that the perp flange may be incorrect as the larger bore would emphasise this.
Is the flange check against any other features?
