Dunno why that is.. unless
1. he cant keep up with the demand
2. gave up on us mark 8 folks..
*shruggs*

it's a great product that greatly increases the service life of the entire air ride system.

I'm glad I got my hands on one.. .while they were available!

Someone should contact Eddie and find out WHEN and IF he's going to get these great products back into production
 
I have a 94 Mark VIII. I recently replaced the air bags on the front with rebuilt air bags. Since then I have noticed that I no longer get the warning that was earlier described in the forums, but my car is riding rougher than hell. When I go over bumps it makes a loud clunking sound. Coming from the rear. The bags are tight, and the car seems level. Any ideas on what could be causing this. Seems that if I park on a hill that the cars rear bags will pump up to bring the car back to level. But she still rides rough as can be and makes the clunking sound for even the smallest of bumps.

Any ideas?

Yeah I checked that, the biggest thing that bothers me is the extremely rough ride, the clunking happened about the same time I noticed the rough ride. I have talked to several people and was referred here, cause no one has any answers much to my dismay : /

better way to measure is from the top arc of the fender well to the bottom dead center of the rim, not the tire.. but the rim

You can use this theory for side to side measurements(front left/right or rear left/right), but the front fender well shape/heigth is different from the back. So if you measure the front and the rear and they are the same, the rear of the car will actually be higher than the back. It would be better to set the tires to the correct/same air pressure and measure off the ground at the rocker panel if you want to be precise, but I was merely giving him a "visual" technique. To compare...my car sit level at the rocker panel, yet my rear fenderwell lip is lower than the front fenderwell lip.

Dick....key words in your description of your issue is "even the smallest bumps"

If it is indeed the rear, you either have bad shock mounts, or some other part of your rear shocks are loose(i.e. lower shock bolt, upper mount torn).

Lift the rear of the car up on one side using the circle subframe "pad" just in front of the rear wheel. Lift it until the rear wheel just barely leaves the ground, now look just above the top of the wheel at the top of the shock. Notice any cracks/tears or is it just plain broken? Check BOTH sides this way. What happends is the shock mount is actually holding ALL the wieght of that sides suspension/torque on the sway bar from the other side being down. This will show you all the stress points on that mount.

Next make sure the lower shock bolt is TIGHT! If the hole bolt/nut combo turns with ease of a wrench, than its loose.

The only other things you'll be looking for are possible broken exhaust hangers. With the car sitting at stock level, lay at the back of the car and grab one of your mufflers and shake it back and forth....hear any "knocking"? If so...figure out where and fix it.

Reasearch J.. REASEARCH..

It's not a "theory".. its the PROPER way to adjust the Mark 8's ride height according to the ford service procedures found on the ford CD.

Here is the section cut directly from the page

13.Measure from the bottom edge of the wheel to the wheel well lip.

-- This must be a vertical plumb measurement.

-- The correct dimension is:

Front 622.3 mm, +/- 6.35 mm (24 1/2 inches ± 1/4 inch)

Rear 615.95 mm, +/- 6.35 mm (24 1/4 inches ± 1/4 inch)

Notice there is a 6.35MM difference between the front and rear measurement?

I know you like to help, and love to debate, but please lets "stick to the facts".

Actually that is incorrect also, because the front tires are under a great deal MORE load than the rear tires. Check the weight distribution numbers for the mark 8 and you'll see what I am referring to.

Inflating them to the same PSI will not make them "even" due to the additional load on the front, compared to the rear.

Thats true about the tire pressure, but I was never arguing what the "actual procedure" for ride heigth was. Initially I was trying to help him "eye leve" his car by looking at the body line on the rocker panel.

You're measurements above are FACTS that show the rear fenderwell is smaller than the front(hence the smaller rear measurement), which in turn will give you a different measurement. Plus/minus a 1/4" is a lot if they are both the opposite from each other. Eccentially you're right and I'm wrong, but take just the actual measurements(before the plus/minus), and you'll see why I was saying that measuring your way doesn't work.

Visually, its easy to look at the rocker panel for levelness(lol), but you can see the rear fender well has a shorter arch. That is a fact, so thats what I was going off of. But I have coils, what do I know. :D
 
Whatever, lol, you we were having a argumentative conversation and you're just going to give up! :) Atleast I'm making sense this time...other times I go off on some technical rampage and overthink things. You have a good one too :D
 
Hey guys,

So far it's been holding up on height. But I still get a warning light, just right away now instead of 90 seconds after. It's about 5-10 seconds after I start the car. It only happens 3/4s of the time.

So according to unity,

If the check air comes up right away you could have a bad relay, a dislocated ride height sensor with a leaky bag(s).

It's possible that the relay could be bad on this junk yard unit I got. The compressor was the noisey part which is much better now. So maybe I replaced a bad compressor and good relay with a good compressor and bad relay. At least I still have the old one and can swap to see if there is a difference. I didn't do anything to any ride height sensors while swapping units. It doesn't mean they aren't bad but how do you tell? And so far it hasn't dropped at all from when it filled back up. I will keep an eye on it for leaks from the bags and maybe do another leak test now that the compressor is working.

I am not concerned as much with this problem because as far as I am concerned it's is working for now. I can at least drive, the little that I do, without bottoming out. I know there still lies a problem if I am getting the warning light though. So anyone have any suggestions of what to do to narrow this problem?

Thanks J.
Shouldn't Ford have checked for these codes when I brought it to them? I'll look into getting codes scanned and figuring it out.

Also it's wierd that whenever there is a problem the self run test on the info center inside the car always says the air suspension is ok. I've never seen it say there is a problem. Anyone else ever see it show that there is a problem?

No problem :D My car is converted...so it always says the air suspension is ok, haha.
