Removing air suspension, replacing with coils

[USMC_Buckaroo]

Howdy Egan,

'Boy Howdy' was that a great post!!!

I have been babying and milkin' my '03 for months, attempting to figure out how best to extend the life of the rear air suspension system. Figured out for a while that if I left the door ajar {in my driveway} the bags wouldn't deflate {worked for a while} Tried several other gyrations until the compressors finally gave out.

I'm retired and pushin' 60 so wasn't excited about jumping under a vehicle again but...after reading your article and how easy you made it seem, I think I'm gonna 'Cowboy Up' and do it myself!

I really want to thank you for taking the time to post that wee tutorial, it really ABC'd me and pushed me into taking the project on...again, Thanks!

Anyone know how to get the 'service air suspension code' off the dash, after removing the height sensors and compressor?

[USMC_Buckaroo]

Bump!


I'm interested in the potential answer to this as well.......




TIA.

Howdy All,


Further, I was hoping to get some friendly feedback from the great members here on this particular set of rear coil springs....

To get rid of service message take it to HUMMER to have them reprogram the ecm

Actually, it does not. Maybe I got lucky, but after a program, revert to OEM, and program I no longer receive the air suspension message. It's been at least a month.

Note I've also run the battery dead for two days, yet no error message.

Can anyone tell me if it rides better or worse with the coils??? I have an 03' with a "service air suspension" and the garage says he thinks its the sensor but no way to tell for sure. A new sensor is 500 bucks and I can get the whole coil set up for that, but I'm worried it will ride really stiff. Any feed back would be greatly appreciated! I also need a new exhaust for it but can't seem to find a stock exhaust for a hummer. It has a flow master now and its pretty pricey to replace.

As long as the springs each have a different part number or they are a "set" and state right and left and you get the four rubber pcs. go for it.

I went with OEM springs and there is a difference between the two.

Some info links below, good luck, Ed

Howdy Easy Ed,

Mucho thanks for reaching out a helping hand pard', and providing those links.

In one of them you said " pulled the compressor and leveling sensors out completly "...I don't suppose a more detailed description of precisely how you do this exists anywhere? I'm recently retired from the home building trades and could easily design/build you your own personal cathedral, but, it's been MANY years since my days of tinkering with race cars and hot rods....heck, the only mechanical tools I own are a set of Husky brand sockets my kind wife bought me for Christmas. Sufficient for household undertakings but for anything more than that they are

Sorry Buck but all the stuff that I removed is not something I would recommend to anyone unless they really feel comfortable in doing so and also sorry to say there is no detailed "how to" to remove it all, I just got crazy in removing mine as seen in the pic's cause it pissed me off for the last time

Pulling the compressor is not hard, few bolts and electrical connectors and hoses to the bags, rest of the replacement is in the links. Anything left in the way of wiring harness to the compressor and to the sensors can be wire tied up. Removing the relay up on the front frame rail along with disconnecting the battery for a few may prevent the "Service Suspension" light from coming on.

Best of luck, Ed
