Yeah, makes sense to take all the plates off. You can leave the sub frame on, which will make it easier to reinstall the plates, once you get it back.Transmission, diff drain, transfer case drain and fills, coolant, and brake fluid change. Lubricate shaft.
Figured the transmission and front differential would at least require the plates to be removed.
Normally I do most of the services myself but my driveway and job changed which made it more difficult to have time and to get under. Had these plates for 2 years now!
