Ride Height
WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2001 Lincoln Navigator, 2001 Ford Pickup, 2001 Ford Expedition, 2000 Lincoln Navigator, and 2000 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
Use hand tools to adjust riding height. DO NOT use power tools.
NOTE:
On vehicles with 4-wheel air suspension system, see
RIDE HEIGHT ADJUSTMENT under ADJUSTMENTS in appropriate ELECTRONIC article.
- On vehicles with front air suspension system, air shock absorbers must be vented prior to adjusting riding height. To vent shock absorbers, connect New Generation Star (NGS) tester to Data Link Connector (DLC) located under steering column. Select AIR SUSPENSION CONTROL MODE under ACTIVE COMMAND MODES menu. Select VENT FRNT to deflate front air shocks.
- Hold 30 seconds to allow complete system venting. DO NOT disconnect NGS tester. Keep NGS tester in same mode to keep system at diagnostic mode at time of ride height measurement. If NGS tester is disconnected, system will go to operational mode and based on signal inputs will level vehicle to specified height.
- Raise vehicle on hoist with frictionless plates to support front wheels. Jounce vehicle to normalize static ride height. Measure distance between center of lower control arm front bolt and ground (STEP 1 in illustration). See Fig 1. Measure distance between bottom of steering knuckle and ground (STEP 2 in illustration). Subtract smaller measurement from larger measurement. This is riding height measurement.
- Riding height should be as specified. See RIDE HEIGHT SPECIFICATIONS table. If riding height is not as specified, tighten or loosen torsion bar adjusting bolt at each side as required. Ensure to check ride height at each side after each adjustment.
- After mechanical ride heights have be adjusted, using NGS tester, select SAVE CALIBRATION VALUES under ACTIVE COMMAND MODE menu to calibrate control module. Scroll through warning message and save FRONT (turn from OFF to ON). DO NOT save rear ride heights. Rear ride heights are precalibrated values already stored in control module.
