Leaking Air Helper Spring System on 2004 Honda Pilot


2004 Honda Pilot 4WD. My system stopped holding pressure. I have not found the leak yet. It was inflated to ~30 PSI and the hitch weight was likely 500lbs. I was looking at replacement parts when I notices that it says it should be used on 2WD models. I did not see that when I order the system. Why is it not recommended for 4WD? Could that have lead to the failure?

Actually, the Air Lift # AL60740 can be used on 2WD or 4WD vehicles, I've confirmed this with my Tech Support contact at Air Lift.

Usually, a leak occurs at points where the air line was cut to length. It's important that these cuts be perfectly square, so using a tubing cutter like # AL10530 to get nice clean cuts is very important.

The easiest way to find the leak is to add air to the system, then take some liquid dishwashing soap and dilute it with a small amount of water. Use a small paintbrush to paint the soap solution on all the hose connections. The leak will make the soap bubble up so its easy to locate.

If the leak is at a fitting where the hose meets the air bag or a fitting, remove the hose from the fitting, and use the cutter to get a nice, clean and square cut. Then reinstall the hose onto the fitting.
