We keep getting the run around from shops in our area and after doing a lot of research we decided to just replace this part on our own. We have found an EHC for just over $800 online but thought we'd ask on here - if anyone is parting out a is4.8 or knows of where is a good place online to buy them that is more reasonable, please let us know! You can call Brad at 970-203-4523 or Carroll at 720-470-9845 on weekends. (Or post to the thread) Thank you for your help!
