Just to add my 2 cents to this - I find that the attitude the car takes
when parked depends directly on who was in it when it was driven. The
geometry being what it is, when the car comes to a stop with weight on
the driver's side only (As mine is 95% of the time, and I weigh 225) the
only way for the left rear suspension to push the body back up to it's
relaxed height would be for the tire to slide sideways! I tried this
out on an alignment rack with sliding pads and the car came right up to
level every time I got out. When one weighs over 1/10 of the overall
vehicle weight there isn't much chance of stopping this effect, other
than the individually-controlled air shocks some guys have installed.
(Not replying to you directly, Richard, by the way! You're right about
front springs too - mine made an enormous difference)
If you are worried about the car leaning to the drivers side, your focus
needs to be on the front suspension, not the rear (with a swing-spring
car). The point of a swing-spring is that it swings - it therefore offers
no resistance to roll. Well, one leaf is fixed, so it offers a very little
resistance, but not enough to cause or to fix a lean to one side. Any roll
issues should be addressed by the front springs and/or the anti-roll bar
(unless you use adjustable air shocks at the rear, which always strikes me
as a bodge that addresses the symptom not the cause, plus front springs are
so much cheaper anyway!).
People talk about "rear end drivers side sag". That talk scares me - do you
really think the car is only sagging to the drivers side at the back???
Unless your chassis is twisted, it should be leaning by exactly the same
amount at the front!!! Because of the styling of the car, it tends to be
more visible at the rear, so I guess that's why this phrase arises. What
worries me is that people think that, just because the sag is more visible
at the rear, it must be the rear suspension that needs fixing...

I've been following this thread because my 1500 suffers from driver's side
rear end sag and my next project is to fix it. I've been told to "replace
the spring itself", "replace the shocks", "do both", "replace the front
coils". I had planned to replace the spring, but after reading what Greg has
done i wonder if that might be the solution. Any advice, thoughts from the
experts?
Thanks,
Dennis
