Question:

The threads on the connector to the airbag on the driver side is leaking after soapy water application. #88338. What do you recommend as a fix? What tool is best for removal of the connector since an open wrench doesn’t move in the tight space?

Expert Reply:

To remove the valve on the Air Lift LoadLifter 5000 Ultimate Air Helper Springs item # AL88338 you will need to remove the air spring from your truck. You can't turn that valve inside the bracket. Once off I recommend using the Replacement 1/4" Elbow for Air Lift Ride Control Air Helper Springs - Qty 1 item # AL21837 in case you have a bad fitting that way you do not have to repeat this process again. I wish there was an easier way but those brackets are built so closely to protect that fitting. I have linked an installation video below to help you out.

The replacement bag for that system is the Replacement Air Spring for Air Lift LoadLifter 5000 Ultimate System - Rear Axle - Qty 1 item # AL84297.

What worked for me was remove pressure from the bag by removing the hose. Remove the nuts from the upper U bolts (they go over the frame above). Find something that will hold the bag down (boards, wire, etc.), and use a wrench to reach the fitting from the tire side. Removing the tire will give you better access. I replaced my elbow with part number 21839, it's a straight connection. A socket easily fits over this part for removal. If you're concerned you could get a dirt build up where the hose connects, wrap it in electrical tape. The next time this union goes bad (if it ever does), a socket, rachet and a hose cutter will be all the tools you need. Don't forget a lot less time and effort to.

I thought my air fitting was leaking but it was the insert that the fitting screws into. Also, one of the plate mounting bolts spun in place. I had to heat the bolt but the whole threaded insert came out. I ordered a new airbag. I got 20 years out of these bags so I guess that's OK. It may be worth putting anti seize on the new mounting bolts.
