Greetings Collective Wisdom,

I'm changing my trailing arms in order to fit larger wheels & tires, and
the only things in my way now are two of the trailing arm pivot bolts
(one on each side).

The bolts may be frozen to the steel sleeves inside the bushings,
because  the entire bushings turn when I apply lots of torque to the
bolt heads.

I've tried lots of PB Blaster & tapping over several days, plus
attempted persuasion by 4-lb sledge, all with no luck. I'd try the
Sawzall on them but don't want to damage either the trailing arms or the
flanges they attach to on the body.

Any ideas?
