CTT Air suspension noise

[gravityalwswins]

Hey all,

Recently purchased '04 CTT. I'm hearing a noise from the right front corner (air suspension?) like an air release/purge, (kind of a fart

is it constant or does it only do it sometimes.  The suspension is auto leveling so often times it'll make corrections to individual corner height.

It is frequent and intermittent, seems more frequent than it should be and only the right front corner

The suspension compressor gets filtered air from the right air filter box via a pipe.

The air also gets dumped via this pipe back into the air filter when the suspension gets lowered, whether done manually or automatically.

Try lowering the suspension via control selection and listen for the gushing sound.

If your getting a gushing sound when the suspension lowers, the air suspension compressor supply pipe may not be connected properly.

The pipe connects to a nipple on the right air filter box.

There is also a pipe connection approximately 5 inches from the filter box back towards the compressor. Sometimes this connection also is not secure. You can see this connection from the engine bay near the right filter box. It is circular and has a green ring which is visible.
