You need to de-tweak the roll-bars with the hubs and upper links removed. And before de-tweaking, make sure the wishbones drop freely under their own weight, and that the roll-bars are free in the holders.
You use the roll-bar links to set the tweak. Lengthen one side as necessary so that the wishbones rise after the same amount of movement. I do this using a ride height gauge under the wishbone. E.g. I may have to lift the RH wishbone 5mm before the LH one starts to lift up. Make sure it's the same the other way around, and adjust the roll-bar links if not.
If the roll-bar tweak has changed when you reattach the hubs and upper links, then you've got some binding somewhere.
