Removing air suspension, replacing with coils

In fact, if anyone needs spare parts (compressor x2, tank, airbags x2) let me know.

I need the wiring at the compressor end that it plugs into. It looks like is a 24 pin connection and theres another smaller 2 pin connector near it as well. You show it in one of your pics that says you zip tied it to the rear bumper.

Do you still have the bolts to the compressor too, so that I can get mine mounted?

Let me how much shipping is and I can send you payment via Paypal.

Thx,

I'd be interested in your ride height sensors (both sides) if they are good and not broken (which looking at how clean your under carriage is I guess they are perfect ).

Just PM me if interested w.price

Thanks

I left these in place, so let me see if I can pull them out tomorrow. I'll check the service manual, but do you have a picture of what they look like / where they are.

If you look inside rear wheel wells towards front of truck you should see them. Looks like a little piston like thing attached to rear suspension and connected with a cable/plug. Mine are covered with an undercoating from previous owner but I think they simply bolt in with one or two bolts. I don't necessarily need the wiring harness from the sensors back but if you find its easy to take that out as well i'd be interested in it as well. Really just need the sensors themselves though.

Got it. I'll take a look tomorrow when I have the truck back up in the air.

I found them no problem, but I read that if I take them out I'll get a trouble light on the dash. Is there a way to avoid this?

I'll be honest, I'm not sure. I think since you pulled the compressor and don't plan to use you may be able to pull the fuse and recycle the power to clear the Service Air Suspension you will get when the sensors are removed. I think once cleared it won't come back.

Probably best to see if someone who has done this already can answer the question.

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!



Buck.

If you need the wiring that goes from the harness I tied up under the bumper to the compressor & solenoid, I have that. I also have the nuts and bolts for the compressors (nuts&bolts for the front of each, nut only for the rear - there are studs built into the mounting plate).

Keep in mind that this is the 2 compressor setup.

Send me a PM with your zip and I'll get a freight quote.
