Torsion bar idexing?

If everything goes well I'll be putting the front suspension back together in a few days. After I install the control arm bushings, is there a proper index position for the torsion bars? I know with the car on jack-stands and wheels removed, the struts are fully extended with the control arm angled downward about 25 deg. At that point there's no torque on the torsion bar, correct?

Well you could start that way and it will be trial an error to get your ride hieght where you want it.

I seem to remember a procedure in one of the service manuals. Chilton or Cylmer.

Thanks Joe. If I've got my head wrapped around this correctly... if you pre-loaded the control arms without the adjusting cap on the torsion rod, then put the cap on, your going to effectively lower the car. The limiting factors would be shock compression, tie rod length, camber and wheel clearance.

I'll consult the service manuals

With the suspension fully bolted up, torsion bars installed without the end caps, you place a bar in the A arm and press down to make sure the suspension is fully extended. You then place the adjustor cap on the torsion bar with the cap arm up against the top of the adjustor cap cavity. Install the adjustor screw. Rotate the screw until the arm of the adjustor cap is about midway in the housing and set car on ground. This preloads the torsion bars. Bounce it a couple of times and then set the ride height equally on both sides. There is a specification in the manual for stock ride height measured from the inboard arm pivot point to the ground, but that would result in the nose high attitude as shipped from the factory. You can lower the ride height from there to your satisfaction.

That's exactly the info I needed Ron! I saw the spec in Climer's book 3.5" difference from the spindle elevation to the axle elevation. Thanks!
