Adjust front suspension ride height by turning the torsion bar adjustment bolts to compensate for sagging or to level the vehicle after modifications.

Warnings

Tools required

Preparation

1. Park vehicle on level, flat surface and engage parking brake
2. Place wheel chocks behind rear wheels
3. Measure and record current ride height from ground to bottom of front frame rail on both sides
4. Measure and record distance from center of front wheel hub to bottom of fender opening on both sides
5. Determine desired ride height adjustment (typically 0.5-2.0 inches maximum)

Procedure

1. 1

   Loosen front wheel lug nuts
   With vehicle on ground, loosen but do not remove the front wheel lug nuts approximately one full turn. This makes removal easier when vehicle is lifted.
2. 2

   Raise and support vehicle
   Lift front of vehicle with floor jack at designated front jacking point. Raise high enough to allow wheels to hang freely with suspension fully extended. Place jack stands under frame rails behind the lower control arms. Lower vehicle onto jack stands so weight is supported by frame, not suspension.
   ⚠️Ensure jack stands are positioned on solid frame rails and vehicle is stable before working underneath.
3. 3

   Remove front wheels
   Remove the loosened lug nuts completely and remove both front wheels. Set wheels aside in safe location.
4. 4

   Locate torsion bar adjustment bolts
   Locate the torsion bar adjustment bolts at the rear of each torsion bar, positioned in the crossmember behind the lower control arms. The adjustment bolt is at the end of the torsion bar anchor arm. Clean the adjustment bolt and surrounding area with wire brush and apply penetrating oil if corroded.
5. 5

   Mark current adjustment position
   Before making adjustments, use chalk or paint marker to mark the current position of the adjustment bolt head and the position of the adjuster nut on the bolt threads. Count and record the number of exposed threads above the adjuster nut. This allows you to return to original position if needed.
6. 6

   Adjust torsion bars
   Using 19mm socket, turn the adjustment bolt clockwise to increase ride height or counterclockwise to decrease ride height. Each full turn of the bolt typically changes ride height by approximately 1/4 inch. Make equal adjustments to both sides (count turns). For initial adjustment, turn each bolt the same number of turns based on desired height increase. Recommendation: start with 2-3 full turns and measure results before making further adjustments.
   ⚠Make equal adjustments to both sides to maintain level stance. Uneven adjustment will cause vehicle to lean.
7. 7

   Install wheels and lower vehicle
   Reinstall both front wheels, threading lug nuts on by hand. Raise vehicle slightly with floor jack to remove jack stands. Lower vehicle completely to ground so full weight is on wheels.
8. 8

   Torque wheel lug nuts
   Torque all front wheel lug nuts to specification in a star pattern to ensure even seating of the wheel.

9. 9

   Measure new ride height
   With vehicle on level ground and at curb weight, measure the new ride height using the same reference points as initial measurements. Compare to desired height. Measure both sides to ensure they are equal within 1/4 inch.
10. 10

    Make fine adjustments if needed
    If ride height is not at desired level or sides are uneven, repeat the lifting, adjustment, and measuring process. Make smaller incremental adjustments (1/2 to 1 turn at a time) until desired height is achieved. Remember that suspension will settle slightly over the first few days of driving.

Reassembly

1. Ensure wheel lug nuts are torqued to specification after any test drive
2. Allow suspension to settle for 50-100 miles before final ride height evaluation
3. Recheck measurements after settling period and make minor adjustments if needed

Verification

• Verify front ride height is at desired level and both sides are within 1/4 inch of each other
• Verify wheels are properly torqued
• Test drive vehicle and verify normal handling and no suspension noise
• Schedule front end alignment within one week of adjustment to prevent uneven tire wear
• After first 100 miles, verify adjustment bolts have not loosened and ride height remains consistent
