It's the spring plate that you can see in front of the rear wheels. One end
attaches to the housing that holds up the wheel. The other end fits on a
splined shaft called the torsion bar. The adjustment involves taking the
spring plate loose, pulling it off the end of the torsion bar, rotating it
a few splines and putting it back on. Actually, you also pull the torsion
bar out and rotate the other end in the opposite direction. (Both ends of
the torsion bar are splined, with different numbers of splines on each end.)
I know this doesn't make much sense but if you look it up in the Haynes or
Bentley manuals, you'll at least get an idea of what's involved and whether
it's something you want to tackle. I did it on my bus a few weeks ago and
posted some observation and tricks I discovered. It should be in the archives
but if you can't find it let me know and I'll mail you a copy. It's not
THAT terrible, probably 2-3 hours work per side, and I think it's the
"official" way of correcting your problem, though air shocks might work too.
