Re: 05 Equinox PTU & RDM Gear Oil Change
just a few other helpful hints- the drain for the differential is in the very front of the housing, where the driveshaft comes in, all drains and fill ports for both use metric hex sockets, but the transfer case fill port is a 13 mm head bolt. So be sure to have a metrix hex socket set. I bought a set from harbor freight. I have worked on cars a long time and never had the set,but just used it a bunch of times. Probably goes into the category of having a better brand- craftsman, snap on, etc, but for the low use, for now the harbor freight Pittsburgh will work. Also ensure to take the fill port off first, because if you drain it and for any reason the fill plug does not come out, you are in trouble.
