Torsion bar adjustment

[the blur]

on my 2003 Denali XL, I noticed the drivers side was 1/2" lower than the passenger side in ride height. So I crawl under there with my 18mm socket to raise the torsion bar, and noticed that the adjust bolt was almost turned all the way in !!! This is the side that needed to be raised.

On the passenger side, there is plenty of adjustment left. I could probably get another 20 turns out of the bolt.

Is my torsion bar weak ??
can ya'll look under your trucks... and see it the driver side adjuster bolt is almost turned all the way in ????? and the passenger side has about 1+" of adjustment left !!

I could always lower the other side, but I would rather raise the down side. This truck is all stock from the factory.

thx
