I just wasted 2 f*#:" hours replacing this crap ,.and the darn thing didnt inflate" Swapped out Rear suspension bag that was losing air with a Arnott, and after install the crap didnt even inflate enough so had to go back and forth and ended up putting the old one after it not inflating enough" ..now after installing the old one it inflated almost all the way good and just a short drive to the gas station it went down enough to scrape the wheel well" ..Is there a programing you need to do after install or a f*#: magic trick or something to get it to work ? i saw a couple vids and all it sayed was to swapp out' ..thats it ?
