Re: Getting rid of "Service 4WD" message. 03 Tahoe Z71

You'd have to take it back to whomever removed the front shafting and gear. There should be trouble code(s) stored in your truck's ECM. Once you know which sensors (or lack thereof) are causing the trouble code, one could try to fool them into thinking all is okay. Just make sure that all the disconnected sensor pigtails are sealed up with electrician's tape or rubber boots in case you ever decide to reinstall it or sell the truck.
