Suspension advice needed.

A few tips, for what it's worth...

Crack the lower ball joint bolts/nuts loose on the car. Easier than using a vise.

If you're taking out the torsion bars, loosen the nut on the lower control arm shaft that mounts in the K-member. That will let the LCA pivot freely. Take the clip out at the back of the torsion bar.

Is this all because of the bad upper ball joint? You don't have to tear down quite that much to get the upper control arms out.
