Lincoln Mark VIII Air Suspension Diagnosis & Repair
Can I drive my Lincoln Mark VIII with a Failed Air Suspension?
Depending on what failed and to what degree, yes & no.
If the vehicle still has a good bit of air remaining in the air bladder, yes, with the suspension switch off, you could probably drive the vehicle for awhile. Keep in mind that with the air suspension switch turned off(as the owner's manual recommends), what is working in the system will not try to make ANY adjustments. With this is mind, if the system has leak(s) it will go down especially while driving and not even try to keep it pumped up. Why not keep the suspension switch turned on? Depending on what's wrong with the system, if there's a malfunction in the system, you want to turn it off where nothing can over-pump and possibly explode an air bladder.
If your vehicle has very little to no air in the bladders, driving your vehicle is a major safety risk to you and anyone around you! When there's no air in the air spring, the only suspension your riding on is the air in the tires!.....and you'll see real quick that's nothing to speak of. The suspension will be so hard, so abrupt that the vehicle could easily change directions because of hitting just 1 bump.
