As far as I know you must have a scan tool to do the depressurization procedure of the air springs on a H2. Is this true? Does anyone know another way to do this?
This is because I will change the air springs because of a small leak.

 

I would think you should be able to disconnect the ride height sensor and manually move the sensor to delete the air pressure. Put some jack stands under the rear bumper so it wont drop on you.

 

If its turned off, the truck should be depressurized anyways.

 

The bags will still be under pressure even with the truck turned off.

 

I just did this on mine and I know people will complain but I just cut them with a knife while it is in the air on the rack since it will lower quickly if not careful. Do NOT do this while it is sitting on the tires on the ground. There is alot of pressure in the bags but not a blasting pressure

 

Good post. I appreciate it.
Many thanks to ur post. I love it.
