Rear Air Ride Random Drops / Air Blending Door

Part One of Bag Replace...

OK, So I got the bags today, and they are in fact the same ones on it "Factory"... I jacked up the tuck from the rear end as high as my 3 ton would go (not as high as I would have liked). Then I put jack stands under each side of the frame for support and chock/blocks in front of each tire. I then let the jack down all the way (well till the tires were back on the ground)... then I took my knife to the bags... note the passenger had little air in it (or at least compared to the other it had way less pressure). After which to give me more room I cut the bags in half to give me more access... Now the hard part is really (or at least so far) getting the lines off... Only way I could do this was to push the retaining clip in and turn counter clockwise to take the top of the bag out of the frame... then I used both of my index fingers to hold down the metal ring on the bag where the hose connects to it and it tried to hold the line as well and pull, at one point I could not hold the line and gave a tug anyway and it popped out... If you had a buddy here to hold the line as you pulled the bag it would make short work of this. Once I got them both out I said to myself it?s a great time to clean the frame up and use my Eastwood frame restore kit I had sitting on a shelf So I will continue on tomorrow with shots of the frame clean up... I hope this will benefit someone in the future... But just know it is an easy job over all (So Far).

Just wanted to post an update to this thread:

I replaced the air bags and it seems to be fixed, after seeing the bubbles from the last test I felt pretty good about replacing them... While I was at it i also painted the frame and rear axle... looks better than new and no more sag.

Humtech, you post say?s that a loss of 1 mm overnight is the max acceptable drop... Is that realistic? I am wondering what I should expect, I parked my Hummer and plan on measuring the why you post says to measure... I am going to let it sit for an hour, then go out to get the measurement from the bump stop cup to the pad on the axle and then check it agn in the morning...

To be honest, I think it will settle in more than 1 mm.

Hope you have time to read this?
Thanks


Anyone else that has checked can you chime in as well?
