torsion bar setting

[68 440+6 R/T]

I am working on a 70 roadrunner and the ride height adjuster on the lower control arm is all that way in and the cars front end is really low, how do you properly adjust the ride height and how do you tell which bar goes on what side and what end goes into the control arm part.

you need new lower control arm bushings.

End of the torsion bar should have a L & R .

Best to have a Factory Service Manual. Your bars may not be clocked properly.

If numbered, the bar ending in an even no. goes on the right, odd ending number on the left. Bars switched side for side can definitely mess up your ride height. Others have reminded that to make a significant change in ride height (new bars or just changing) the upper and lower control arm bushing bolts should be loosened so the bushing torque isn’t fighting the change. If not wanting to get a realignment immediately, you might try just loosening the LCA bushing bolt for now.

Rotted out torsion bar cross member socket that has let go.... or the last guy didn't install the bars correctly. One or the other.

does the numbered end go into the control arm or does the star shape on the torsion bar go in the lower control arm?

Did you fully drop the suspension with the control arm bumpers removed & the knee in the most fully lowered position to clock the bars ?

Not yet but I will be soon, I know that when you take them out you must loosen the ride height adjuster bolt all the way then they should come out, I would also loosen the lower control arm nut to take the tension off the lower control arm bushing. How do you clock the bars properly, and how do you tell what hexagon end go's in which side, the control arm end or the torsion support end?

Technically, and functionally I can’t see how it matters which end of the torsion bar goes into the LCA, but I’m sure Mopar had a procedure. It makes sense to put the numbered end to the rear where the bar can be checked easily by someone unfamiliar with the car, to verify their specs and installation.
