Hi all,

I have been having issues with my left control arm "sagging" after driving around. I noticed it first on the stock ride height my car was at and thought I had just mis-adjusted it when I replaced the torsion bars. Now I have the car much lower and noticed it again when the left front tire ripped the stainless trim off on a corner. Measuring from the floor to the fender lip it dropped 1.5" compared the setting on the right. This was only from a few drives since I had the car realigned after I adjusted the ride height.

Yesterday I set the height back to level side-to-side, drove it a few miles, and sure enough when I got home it was .5" lower. I did jounce it and make sure it was settled in after I adjusted it, so I don't think its simply settling.

Any one have an idea of how I could keep the adjustor from unadjusting? Or is there another problem in the suspension that might cause this?

Thanks in advance!

Just a guess here,, some adjuster bolts are fine thread and the bolt/nut can be stripped/worn. Or lower control arm bushing wore out.Or check for crackes at T-bar mount on frame. Check upper control arm mounting points and bushings. Just a few check points.

It is unlikely that the adjusting "screw" is backing-out.
It is common to see the rear torsion bar anchor point crack, twist and break-out of the frame. The LCA bushing - shaft can also break-out of the K-frame mounting point.
Time to do a close inspection arount the 2 ends of the torsion bar.

Thanks Doc,

Everything is new, so its not worn out. I'll crawl under for a look and see what we have going on. More soon!

I have also at least imagined that new tbars or all new susp components can take a while to settle in. I cannot explain this so far, but it has happened once or twice. You may just need to drive it more and readjust.

ok I'll hope for that I will keep adjusting and either run out of adjustor screw (its pretty far out now).

I definitely wasn't able to find anything obviously broken, so I'll just keep cranking it back up and see what happens. Thanks Lou..I really didn't want to take it apart....again

MJ

It could be something is messed up, but you can at least try this for a little bit and see how it goes.

Let's hope for the settling instead I'll keep you posted. This morning it was only 1/4" lower than when I set it last time, so hopefully its stabilizing.

MJ

Why don't you overadjust?

That way it will quit, and then you'll have to adjust it lower.........
