LLS question
I noticed that my '02 Navi is sitting down in the back - seems the rear is outta air and doesn't want to pump up.
Will it hurt it any if I drive it about 30 miles to get some parts?

Yes, the compressor runs, but I turned the LLS off to prevent any further damage.
I'm wondering if I drive it with it down on the rear axle if it will ruin the rear shocks, as they are probably holding much of the weight.......dunooo.
I contacted AutoEnginuity about their Ford Enhanced Scan tool but they said the Lincoln uses "UBP" electronics and their scan tool won't work with the Lincoln's air suspension - won't have bi-directional control nor the ability to monitor any LLS PIDs.
I guess the only way to diagnosis this thing is the old fashion way - trial and error.

For the majority of LLS problems, a scan tool isn't necessary. Failures are usually physical.
Turn off the suspension switch.Jack up the rear of the vehicle and let the axle hang loose. Place stands under the frame. The rear air spring folds under itself at the bottom. Letting the axle hang will expose much of the normally hidden area. Check this area for cracks or splits. This is the most common failure area.
If the springs look ok, inspect the line connections at the spring solenoids and the dryer. Turn the compressor on and spray the springs and connections with a soap solution (kids bubble solution works great). I'll bet you find a leak in one of the rear springs. Replace them in pairs.
