I totaly agree with you! I don't have a clue on where to begin on servicing parts of my truck myself. I have a 2000 F150 that I purchased about a year ago. It had been wrecked on the rearend and rebuilt. I have had some major problems with it in the last few months and I'm finding myself having to do what I can to it myself to learn about it and save money. By the way, I'm a girl if that eases anyones mind to my silly questions. LOL

it's not hard girl,just jack it up,loosen the bolt's around it and let it drain.or you can syphon it out,either way will work.use a gasket and you might want to borrow a torqe wrench unless you want to buy one.
if i were you take it to a shop,buy the time you get the gear oil,torqe wrench,gasket material you can get it done for $45.00 to $75.00.depends where you take it.
but then again if you want to start servicing your truckyourself.jump on it.
good luck

Any good parts store that sells FelPro gaskets sell the differential gaskets.Here is the part number for the 8.8;
FelPro-RDS-55431

So, I'm left with the RVT stuff!
As I said, it works well, and the extra time it takes, just gets me out of that much more house work and I can down a few more beers!
A garage with a beer fridge and a TV hooked up to cable is not a bad thing!

Thundercat... there are some good, well-explained "How-To" articles regarding maintenance, etc over at http://www.fordf150.net/howto/
As well, check the "Technical Articles" on this site as well as those at FTW.....
All 3 sources have some excellent information that's easy to follow..

Advance auto parts,$5.80! Part number;
FelPro RDS-55394
FelPro RDS-55394
I don't know of any parts store that does NOT sell Felpro gaskets, and I looked at them all..... They all said no such listing and then they would point me to the RVT section........
Thanks again!

Hey BlueOvalfitter, thanks for the part number for the gasket. I'll pick one up for my 8.8. I have an Advanced Auto Parts about 10 minutes from my house. I like the idea of both a small bead of silicone and the paper gasket. I don't plan on opening the differential up again before I sell the truck (I probably should not have said that).
I got the front differential gear oil and transfer case fluid (Mercon) changed this past weekend. Piece of cake except for the transfer case fluid hits the cross member and goes all over place because it's so close to the drain plug. If you have changed your transfer case fluid before, you know what I'm talking about. Other than that no problems at all.
I am going to torque the rear differential cover bolts to 35 ft/lbs. My Chiltons book does not give a torque spec for these bolts. Does this sound ok, anyone????

I just tighten them up in a criss cross pattern and snug 'em down to what "feels" like a decent amount with a 3/8" ratchet....
Over tightening will cause leaks just as under tightening will.....
Good luck!

That's some of the worst advice you've given yet and that's saying alot. If you give horrible advice and someone takes it and toasts their rear end, YOU ARE PERSONALLY LIABLE for the damage IMO. I hope your "motor oil" is black when you drain it from your differential. I suggest you attend a technical school or stop giving advice on this board.
