Do torsion bars sag?

[72cuda]

Passenger side of the front sits a little low. The adjuster is not rusted, and was initially at about the same setting as the driver side. Gave it three turns or so, and the car was level. After a day or so, ride height is right back to where it started. The subframe connector is not rusted out.

At the end of this season, the car will be stripped and rebuilt, so it's not a burning issue. But from talking to folks and researching the Internet, what I'm hearing is:

- torsion bars sag with age
- torsion bars don't sag, the adjuster is broken
- torsion bars don't sag, it wasn't correctly indexed when installed (given what I'm finding on the rest of the car, I can believe this)  

Interested in peoples' experiences in this area.

A torsion bar is just a different type of spring and all springs will wear out or lose there "spring" over time from repeated use.It is metal fatigue from age,rust,heat cycles etc.

I doubt the T bar sagged in 1 day , they will sag over time , you are positive the rear mount is not loose in the transmission crossmember? Possibly if the adjuster was stripped , it could jump down again , I would check everything carefullly
