Bushes won't cause that and that IMO is not a problem suspension is articulating what else do you want?

I think the corner weights are all over the place due to coilovers causing handling problems which is making you think it's wrong.

You can check by parking on flat floor take measurements from floor to arch front and rear

then jack the front up from the centre of crossmember wheels off floor 2 inch take measurement on the back

Repeat on rear jacking on center of diff and measure front arches.

The compression measurements on the front axle and rear axle will give you an indication of weight each wheel is carrying.

Adjusting it is another longer story.
