When i tighten the bolt for the lower control arm it pinches the bushing preventing it to move. It needs to move, preventing the rubber from tearing.

The Nissan bushing does not move/spin.  It flexes.  That's why you're supposed to tighten the bolt with the car on the ground.

Ok you tighten on the ground, then it goes on a lift with wheel hanging or lots of suspension travel. I dont think the rubber was designed for torsion, was made for radial load.

I think that they were aware.  Have you ever seen a torn or split bushing?

Here's 1973:

Should be interesting getting a torque wrench under the car in that area and applying 80lbs.

You could do it up on ramps or blocks. Just be sure the car can't roll off on you!
