Dana 80 oil change...

Had some fun pulling off the rear diff cover

After removing the ten bolts, I was expecting to find a gasket between the cover and the pumpkin... but after some swearing and some handy working with a putty knife and a hammer (tap,tap,tap,...), got the lid off to find that there was only grey permatex. The problem with this is that it was really tough to get the putty knife in this small gap...

Going with the PML cover, so oil changes should get much easier but am wondering if I should shell out the $25 for a new gasket (or if this is just a waste of money). PML cover is pretty nice (has a plug on top for fill, a plug for level and a drain on the bottom (with magnet)...

Another note: at about 10k miles, the truck started getting a drip from rear diff cover which the dealer "fixed" (maybe they pulled the gasket)...

BTW, I'm replacing the stock gear oil with Mobil 1 (75W140) and some LSD additive... how much do I need to fill the rear end and the PML ??

Rgds,
Ralph-
