I don’t like how ride height is determined, according to my FSM.
On other Chryslers (before FMJ’s), you measured the torsion bar anchor (on LCA – Lower Control Arm) and lowest point at lower Ball Joint, then subtracted the two, to get ride height.
Here, the specs (77 FSM) say the LCA inner pivot bushing should be 10-¼” from ground, with all tires at normal air pressure. That measurement does not compensate for different tire heights.
The tires on my wagon are 25½” tall compared to 5th Ave at 27” tall.
Another service manual (non-FSM) I have says this
Before taking measurements, grasp the bumpers at the center (rear bumper first) and jounce the car up and down several times. Jounce the car at the front bumper the same number of times and release the bumper at the same point in the cycle each time.
- Ride height is measured from the head of the front suspension front crossmember insulator bolt to ground.
- If necessary, turn torsion bar adjusting bolt clockwise to increase height and counterclockwise to decrease height.
- After completing adjustment, jounce vehicle and recheck riding height. Both sides must be measured even though only one side may have been adjusted. Front vehicle height should not vary more than 1/4 inch from the specified riding height. Riding height should also be within 1/4 inch side to side.
I guess they compensated for the taller tires . . .
