Monroe air shocks

You better re-read the installation instructions. You are doing something wrong if you are having issues with both. We would spray them with soapy water and look for bubbles. You can also take them off, air them up and dunk them in a bucket full of water.
Again done this over and over . It takes weeks 2-3 to drop . The shocks say 80-150 psi . They don't even rise unless 80-90 in them most I've ever gotten is 115 . They hold for 2-3 weeks . I can't even get 150 in them but 100-115 and they leak down 75 ish over 3 weeks and stop .
It's got to be cheap made shock not being able to hold .
