'99 Rodeo standard front heights before torsion bar adjustment

[rognik39]

Hi Guys
Does anyone have the original standard ride height reference info for the front of a '99 Rodeo as I have attempted to adjust the torsion bars after finding that one wheel arch was sitting approx 1/4" higher on one side.
The wheel arches are now equal but each of the adjusting bolts that protrude thru the adjuster mechanism one by 20mm which is the side I adjusted upwards and the otherside protruded by 30mm which I have left alone.
I was going to lift both sides higher but I have a suspicion that this may have already been done to some extent.
I guess the reference heights that I want is the height from the top wheel rim to the top of the arch bearing in mind that I have 15" wheels
with 235/75x15 rubber.

The fractory specified Trim Height is 4.69 inches +/- 0.2 inch. In the attached thumbnail the distance is measured between the center line of the upper control arm pivot point and the bottom of the lower ball joint.

It looks like the easiest way to measure this is from each point to the floor and subtract the difference.

The manual says to adjust the tire inflation pressures (I'd assume the factory specified listed on the door). Park the truck on level ground and bounce the shocks and allow to settle.



I'm curious what measurements you get.

Good luck.

Hi
Thanks ill have a go at that in the next few days.
Do you have any theory for the reason why one torsion bar would appear to be cranked up higher than the other with out giving any increase in lift.
I can only think that it has not been assembled with the correct orientation on the splines or that the bar is much weaker. I have also noted an occasional clonk from under the car on the same side but only when travelling and is quite rare!

The difference in the torsion bar adjuctment could be a due to one torsion bar being weaker than the other or when they were installed they weren't indexed properly. I've not done it, but have read where others have re-indexed there torsion bars. Basically it's taking all the tension out of them and repositioning the splines (rotating the bar itself) and re-tensioning them.

I get a clunking noise from my Rancho shocks on turns when its cold. The Ranchos had to be modified to fit. I need to shim the post so the shocks don't slide back and forth on the post.

If you've adjusted your torsion bars I'd recommend you have your front wheel alignment check.

Good luck.
