scannon Posted July 11, 2012 Share Posted July 11, 2012 While installing the new differential struts I pulled the fill plug on the Sierra diff to check the level. The plug has a magnet on it and it was full of filings and a gray viscous fluid that looked and smeared a lot like antisieze. See the before and after pictures of the magnetic plug below. The level is down a little and I decided this was a good time to drain and refill the diff. There does not seem to be a drain plug on the differential. Does anyone know if removing one of the lower bolts on the rear diff cover will allow the lube to drain out? Because of the position of the deDion tube there is no way I can get the Torx driver in there without dropping either the diff or the deDion tube so I can't just remove one to see if the fluid pours out. I'd like to know if this will work before I go to the trouble of removing the diff or deDion tube. BTW, I am starting a new thread about the diff struts.

jlumba81 Posted July 11, 2012 Share Posted July 11, 2012 Not sure about the drain hole but you could always suck out the old fluid. Link to comment Share on other sites More sharing options...
Croc Posted July 12, 2012 Share Posted July 12, 2012 I replaced the fluid in my diff by sucking it out (well not personally.... but you know what I mean!) Link to comment Share on other sites More sharing options...
