Why is my rear driver side hanging low

[Cadman-iac]

Hey Mika,

Greg has made a really good point here about a possible cause for the "tilt" condition.  But instead of a worn or weak spring in the rear, I'm thinking that the right front torsion bar may have been adjusted to keep the car level when an overweight person was sitting in the passenger seat. Once the person was out of the car, the right front corner would rise, and cause the left rear to "appear" to sag.

Like Greg, I recall an overweight customer who had come in to the dealership to have his car worked on, and it had a really bad "tilt" to the driver's side, even after he got out of the car. It was an older Chevy, '68 or '69, so it didn't have an adjustable torsion bar on it.

Maybe if you are able to ask the person who restored the car what condition the front seats were in, such as the springs being collapsed or broken on either side, that could be a clue as to what was done to it, as far as an adjustment to one of the torsion bars goes anyway.

Hey Rick

I believe that might be one of possible reasons.
Next week I can get the car on pit and be able to
measure all corners better, with rear shocks empty,
and adjust the passenger side torsion bar.
Actually I found the car from YouTube before restoration
and sending to Finland, and here is couple of screenshots where
you can see the passenger side door and seat, and how worn
they were. The drivers side was in better condition.
And looking at that condition brings to my mind how much that
mileage 29 900 can be possible...
Maybe someone was living in it but not driving it 😄.

Yes, I'd be interested in what you find out. The seat and armrest are pretty rough looking, so I guess it's possible that's the reason for your problem. An overweight passenger that is.

Took a long time to tell how this ended, but I had more urgent things to do first.
I changed my rear coil springs to new ones, didn't solve the problem.
Inspected the rear shocks many times and thought that it
must be the drivers side shock that's faulty being lower. Jacked lower side up and
put max air pressure (jacked down) and checked them after few days, they do not leak.
Then today I adjusted down the front passenger torsion bar and that's what
made the rear even ! First 4 rounds to see, then 6 or 8 rounds more.
Amazing what an effect. Now the drivers side rear shock is only 1cm lower,
maybe because of being under more pressure for long time, but now I am satisfied.
In that picture outside of the garage when the situation was the worst,
I only concentrated level surface in the rear, but the passenger side front
wheel was on a bump so it twisted the drivers side rear more down.
Stupid me not to notice that earlier when got a hint from here.
Thanks a lot for your support !

Now you need to have your front end alignment checked. You changed the ride height on the passenger side. You affected all three. Caster, camber and while very little, the toe-in.

Damn, that's true.
If they were aligned in the first place..

That's the reason I never moved my torsion bar adjustment to make up for the sagging rear on the left side. I replaced the springs.
