pump up rear

[03blackvegas]

I would like to "manually" raise the back of my car, has anyone done this, and what was the procedure. Just to clarify I'am talking about using an air compressor to insert air into the system to raise the rear up, due to a problem in the system. Thanks.:confused:

It is easily done. Underneath the rear of the car, on the driver's side you will see a bracket attached to the watt's link arm. If you loosen two bolts that attach it to the arm you can slide that bracket left and right. The more you slide it to the driver's side the lower the car goes, and to the passenger side the higher the rear will ride. Simply slide it a bit, then lock down those two bolts. Let the car down, switch the suspension back on and start the car. The car will raise or lower to the new height you set.

It usually takes me a few tries to get it right where I like it. I raised mine up some time ago because I liked the more raked muscle car look. However, I eventually sat it back down as I was ultimately more interested in balance and cornering than I was in how it looked. Of course, YMMV.

For god's sake, please remember to turn off the air system via the truck switch before you get under your car and start frigging with stuff.

"due to a problem in the system"

I believe its broke and thats why he wants to raise it. There is a way, but I'm sorry I do not know it. Hopefully someone who does will chime in.

Thats correct, I need to insert air myself to raise the car up, at this time it no longer does it automatically. I see a hose coming off the pump, but I'am not sure how to take it off, or if it can be put back on after it is removed. I was hoping to remove this hose, use an adjustable air blower, and slowly add air till I get the back end where I want. If the hose would not go back on I would try to crimp the hose to avoid a leak.

Ah, I see. You want to use an external air compressor, not the car's air compressor. I see what you mean. I've never tried that, but I'd think you'd need to add a check valve or something to the hose so that it didn't bleed all the air out once you disconnected the compressor hose. I don't think just crimping it would really cut it. It may seem tight but it'll slowly bleed.

Really, I think you're better off just fixing or replacing the car's built in compressor and letting the system manage itself. I'm sure you know that, though. Good luck and let us know what you figure out with this.

Be extremely careful. The compressor in the MM's does about 20psi I believe. Home air compressors can shoot air out at 100psi. You could blow something up and cause even more damage. Just get it repaired.

So you want to add air and leave it?

I'm not positive how it is on the MM, but i know a thing or two about air suspensions....

The way most people do it is use a schrader valve on top of the bag. In this case, where its not easily reached, you would use regular push fittings, and run a tube to where ever, with a schrader valve to fill. T it off, and it will fill slowly, or do each side seperate. I believe the MM has accumulators....but i can't remember.

It may be possible to remove the fill hose from the compressor and do it there. I have no clue what type of fitting is on the end. If it's possible to change or adapt to it, you would simply adapt it to fit a shrader valve. The line SHOULD already have a check valve on it. Sometimes they may not, so if the PSI builds too high, it simply vents through the compressor.

A picture of the compressor (my brother isn't home, i can't look at his), and a description of your problem would help.

Perhaps removing the air bags completely and going with coil springs in the back would be a good answer if you're not wanting to repair the air ride system. Just a thought.
