Well the time has come. I need to replace the 4 air bags on the drive axle. I did the front and tag last winter and I am pretty familiar with this process but I do have a few questions for anyone who has done the drive bags. getting to the 2 back side bags looks pretty easy, getting the lines off and pulling the fitting so you can drop the bag. but looking at the 2 front drive bags it looks nearly impossible to get up in there and get the lines off extremly tight area. Any suggestions from someone who has tackled this job would be greatly appreciated. ON the last bags I did I had to get up there with a blow torch to heat the fittings so they would come loose. doesnt look like enough room to do that on the front drive bags. Please drop me a pm, I can give ya my phone number or give me yours. bag has blown so gotta get done.  Thank you.  Richard I know I saw a post from you about doing them..

Wrench that fits, four lb engineers hammer to hit the wrench, cut the fitting on the air bag off with a sawzall. Readers digest condensed how to. Angled wrenches help to spin the nut off.

X2 on Richard's post....Highly recommend getting an angle wrench, if you can, if not these are the tools I had to use....1/8 turn with the combo wrench, 1/8 turn with the crescent wrench, flip crescent wrench then 1/16 turn, then the ford wrench for another 1/8 turn.....you get the idea.  I took all four to get it tightened.....a real pain but doable. Almost forgot, a short length of pipe for the final torque.

Check your size before ordering. I have learned that Newell used different sized fittings from coach to coach.

Mine measured out to be 1 7/16.  So at Northern Tool they could not find an angled wrench in the store at the last minute.  They also did not have a 1 7/16 combo wrench so I picked up a combination wrench in 38mm.

The lines going to my bags are 1 1/2". So has anyone ever disreguarded the giganic air line going to the bags and replace with a smaller line ?  I know the new coaches have 3/8 airline going to the. Also I was wondering if you could bypass the welded in tanks and just pull air of the primary round tank. I got to tackle this pretty quick so just trying to find out what others have done

Adam , Check my thread titled "Air bags for 316" We did what I think you are considering. I plumbed to the square tanks. Richard has bypassed the tanks. Check his thread for that info.

TY will look at that now. I want to bypass the tanks or change the plumbing

Dont forget tag axle bags get their air from the welded in tanks. Follow the lines.
