Is this a symptom of worn out torsion bars?

memeroy sux so someone correct me if I'm wrong . I think all factory manuals state that you'll meed to remove the upper arm bushing thru bolts or atleast remove the cone shaped bumper under the upper arm to get the lower arm down far enough to properly insert the torsion bars.
If you do pull them back out, roll them on a flat floor or table. Some bow is expected given their age. Over 3/8 inch bow is cause for replacement.
Again factory manuals are worth their weight in gold.
