2000 Lincoln Ls Suspension Recall 00V359001
NHTSA: Action Number: N/A Service Bulletin Number: 00V359001
Nov 03, 2000Component:
SuspensionPotential Units Affected:
Ford Motor Company
Summary: Vehicle description: passenger vehicles. The front suspension lower ball joints were not tightened to specifications when they were attached to the lower control arms.
Consequence: If the ball joint attaching nuts are not adequately tightened, they can loosen and, ultimately, result in fracture of the ball joint stud. If the ball joint fractures, control of the vehicle could be affected, increasing the risk of a crash.
Remedy: Dealers will inspect the torque on the two ball joint attaching nuts. Vehicles with loose ball joint attaching nuts will either have the fasteners tightened to specification, or if necessary, the ball joints will be replaced.
Notes: Owner notification began november 24, 2000. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact ford at 1-800-392-3673. Also contact the national highway traffic safety administration's auto safety hotline at 1-888-dash-2-dot (1-888-327-4236).
rfitzgerald - 1996 Lincoln Town Car - Steering & Suspension - 1/11/2012The air pump on a 1996 Lincoln suspension keeps making a humming sound.
1/11/2012 Spoon SportsIt sounds to me like you had some leaking air springs. Your air compressor tried to keep up, but now is about to be burnt out.
TC air suspension diagnosis: http://www.lincolnsonline.com/tech/00061.html while this is for pre '98 models most everything is the same except the electronics and therefore the electrical tests.
Replace air springs on a '90 to '97 model Town Car: http://www.lincolnsonline.com/tech/00132.html the suspension will be different and some support components located in different places but this should help.

Air compressor replacement ('95 model): http://www.lincolnsonline.com/tech/00012.html your car will have the air compressor under the air cleaner at the front of the engine compartment on driver's side.
These tech links will help you better understand the suspension and how to fix it.
John - 1995 Lincoln Town Car - Steering & Suspension - 1/6/2012You can hear air pump come on while driving. Car stays level. Overnight the suspension appears to hold its pressure because the car does not sink. Air bags have about 100K miles on them. Is this a computer problem or should I suspect an air leak?
1/6/2012 Spoon Sports"Overnight the suspension appears to hold its pressure because the car does not sink" - Then its not a leak otherwise you car will just sag.
A Lincoln Town Car's air suspension uses a small, separate air compressor under the driver’s side left fenderwell, and air lines run to the air bags. On top of each air bag is a electrical valve that serves as a relief valve that allows air to be exhausted when activated. The valve senses the amount of air pressure within the air bag to keep both sides equal. These valves are operated via a leveling sensor that is attached to the body of the car and to the rear axle by a movable arm. When the rear of the car drops because of an increased load, the arm is pushed up, turning on the air compressor and filling the air bags to level the car. When the load is removed and the arm moves down, indicating that the back of the car has risen, the sensor opens the valve on the air bags and allows air to escape, lowering the car.
If the back of the car is low, indicating that the air suspension is not working, and the air suspension light is on, check the fuse. If the fuse is all right, make sure the air-suspension switch in the trunk is on. This switch is used when the car is in for service. Always turn off the switch before lifting the car, because the sensor will think the car is rising and keep the air bag valves open, ruining the rear air suspension.
Turn the ignition key with the engine off, and listen for the compressor to come on while pushing down on the rear bumper. If it does not come on, test the switch terminals for power with a circuit tester. If one terminal has power and the other does not, replace the switch.
If there is power, turn the switch to the "Off" position, raise the vehicle and place it on jack stands in the rear. Inspect the leveling switch on the axle, making sure it is not bent and is connected. Use an ohmmeter for this test. Pull the electrical connector off the switch. Loosen the arm of the switch from the axle. Test the switch with the ohmmeter by checking across both terminals while slowly moving the arm. There should be no continuity with the arm down. As the arm is raised, there should be continuity. If not, replace the switch. If there was continuity, connect the arm and the electrical connector.
Check for Power
Put a floor jack under the axle and raise the axle so it is just beginning to lift the car off the jack stand. Turn on the ignition. Turn the air suspension switch to the "On" position. Use the circuit tester to check for power at the leveling switch. If there is power, turn the air-suspension switch to "Off" and lower the car.
Access the air compressor in the front, under the hood, and check the electrical connector for power. If there is power, check for a good ground. If both are good, replace the compressor. If the compressor works and the car does not rise in the back, replace the air bags.
rfitzgerald - 1996 Lincoln Town Car - Steering & Suspension - 1/1/2012The "check air suspension light is on".
1/1/2012 JimmThe ride will be different - whether it is as 'good' is fairly subjective. There are shock absorber kits available to convert the air suspension to more conventional hydraulic or gas-filled shock absorbers.
Monroe Part # 90003 Air Spring to Coil Spring Conversion Kit - is one such kit for around $147.00 from www.RockAuto.com among other auto parts sources.
1/1/2012 HouseCallAutoProbably your Town Car just needs new air springs. Do you still hear the compressor turn on? If not check the fuse for being open. If it runs and the car pumps up when it is started but sinks after the car is parked for a while, replace the air springs. They can be had from Strutmasters.com for $84 each.
nestor - 1999 Lincoln Navigator - Steering & Suspension - 12/30/2011I thing is a leveling switch but I am not sure. Than you in advance
norma - 2001 Lincoln Navigator - Steering & Suspension - 12/30/2011158,000 I haven"t had anything done related to this problem. When i drive my suv it bounces very badly the ck supension light is on. this problem just started last saturday.
Jill Cox - 1998 Lincoln Mark VIII - Steering & Suspension - 12/23/2011I just had 2 used front tires put on but they didnt turn off the air suspension ride button in back could this cause damage or this. and also about 8 months ago i had a cv joint replaced.
Greg - 2000 Lincoln Navigator - Steering & Suspension - 12/22/2011When I turn off the car it will lower a bit but not all of the way and it is still 1/4 inch lower on the driver side. I have replaced the front air shocks and the back shocks no difference still 1/4 inch shorter.
12/22/2011 HouseCallAutoIf that is all the problem, you are measuring and just 1/4" difference, this small amount is insignificant. Do nothing. If it really is making you crazy you can adjust the torsion bar to raise or lower the front left and front right sides. Just turn the bolt enough to even it out.

12/13/2011 Spoon SportsYou mean the compressor?
If diagnostics lead to compressor/dryer assembly replacement, use the following service procedure to insure complete and thorough service.
1. Using the New Generation STAR (NGS) tester, vent the compressor/drier assembly.
2. Using regulated shop air, blow out the air lines from the drier to the front fill solenoid valve and from the drier to the rear fill solenoid valve, before installing the new compressor assembly.
3. Replace the air suspension compressor assembly. Refer to Workshop Manual Section 204-05 for compressor installation instructions.
4. Replace the front fill solenoid. Refer to Workshop Manual Section 204-05 for replacement instructions. The front fill solenoid must be replaced because in these cases, it may have sustained damage from the drier desiccant or other contaminants.
5. Connect the New Generation STAR (NGS) tester to the vehicle while the vehicle is parked in the service bay with the engine running.
6. Install a pressure gauge capable of reading 400 PSI at the front air line (Figure 1). Using the scan tool, command the compressor ON. Check the output of the compressor on the gauge:
a. If the compressor does not output at least 110 PSI within 30 seconds, replace the compressor again and retest.
NOTE VERIFY THAT THE SUSPENSION RAISES PROPERLY.
7. Using the scan tool, command the front of the vehicle to raise up one inch. The front suspension should rise one inch in 25 seconds or less.
a. If the compressor output is near 300 PSI, check4or air line or solenoid restrictions, repair as necessary and retest. Otherwise, proceed to Step 7b.
NOTE SUSPENSION UPWARD MOVEMENT CAN BE VERIFIED BY MONITORING EITHER OF THE FRONT HEIGHT SENSOR PIDS, WHICH SHOULD DECREASE BY .35 TO .45 VOLTS.
b. If the front of the vehicle DOES NOT raise, check the front pneumatic system for leaks, inoperable or blocked solenoid valves or pinched air lines. If an issue is found, repair as required and repeat Step 7 to verify proper operation.
c. If no problem found, continue to Step 8.
NOTE VERIFY THAT SUSPENSION PROPERLY.
8. If the front of the vehicle DOES raise, use the scan tool to command the front of the vehicle to lower one inch. The front suspension should lower one inch in 20 seconds or less.
NOTE SUSPENSION DOWNWARD MOVEMENT CAN BE VERIFIED BY MONITORING EITHER OF THE FRONT HEIGHT SENSOR PIDS, WHICH SHOULD INCREASE BY .35 TO .45 VOLTS.
a. If the front of the vehicle DOES NOT lower, check the front pneumatic system for leaks, inoperable or blocked solenoid valves, an inoperable vent solenoid, or pinched air lines. Repair air lines or replace solenoid valves as required.
9. Repeat Steps 7 and 8 for the rear. Command the rear of the vehicle, and monitor the rear height sensor PID. Voltages should increase when the vehicle is lowered, and decrease when the vehicle is raised. If the rear of the vehicle does not raise and lower as commanded, inspect the rear pneumatic system for leaks, inoperable or blocked solenoid valves, an inoperable vent solenoid, or pinched air lines, and repair as necessary.
10. If the vehicle raises and lowers normally in both the front and the rear, test drive the vehicle to confirm the repair.

12/6/2011 Spoon Sports"Bolt laying on ground What happened and why" - As far as i know all ball joints use a castle nut with a cotter pin, the only way i can think of of newly installed parts breaking down is a mis-installation (Probably bolts werent tightened or the cotter pin wasnt installed.
