Right side Higher than Left side after hitting Raise button

**Repurposed Thread**


I toggled the suspension raise button on the console today and noticed only the passenger side of the vehicle is raised. The compressor kept on running so I shut the truck off. It's remained the same height one side for about 3 hours now and won't return to a normal height.

The left rear spring is also sagging. When I unlock, I can hear air pumping into it, but there is a hiss right away and the inflation stops completely. This corner of the car sits way lower than any other corner.

What could be causing both of these issues?

Sounds like a blown air spring if the compressor is running.

Yup. Found the spot leaking air. I have 2 rear bellows on order.

Similar issue also. Left rear can hear hissing and sags. Took to a shop to get on lift and look for leak. Lifted up to level 3 while on lift. Sprayed bag with water no bubbles, bag full and no hissing at all. 2011 gl450 on post lift running and no issues. Set GL down on shop floor, and stayed perfect in ride height 3. Put in normal with no issues. As soon as he backed it out of shop the left rear dropped and hissing.
