Why can't I find a gasket for my differential???
No one seems to carry the 12 hole gasket for my rear differential cover on my 97 f150, 5.4L 4x4. Everytime they look it up it says mine should be a 10 bolt or something. How do I read the tag on the differential or does it say on my door jam sticker?
thanks
thanks

the friction modifier is only needed in a limited slip axle, if you look on the axle by the diff cover there should be a stamped tag with a code on it which can be looked up to see exatly what setup you have. post up your code and i can look it up

You sure there's nothing before that "55"?
Look on your door sticker - if the axle code is 19, you have a open 3.55 and you don't use modifier. If it's H9, that's LS and needs modifier.
It's definitely a 9.75.

Hey J!
Yeah mine says 19 under Axle, and under the R it has 8 whatever that means. I already put the cover back on using silicone with 3 quarts of Amsoil severe gear 75W90 oil and and a 4oz thing of Amsoil's friction modifier...that shouldn't matter that I added it even if I don't have LS right? Jbrew got me hooked on Amsoil now, I use it for everything lol. I don't know why my owners manual says to add friction modifier and makes it sound like I have the limited slip...

Axle Codes
The following lists the gear ratios on rear axles.
19-3.55 non-limited slip (Econoline, F-150)
18-3.08 non-limited slip (F-150)
17-3.31 non-limited slip (Econoline)
H9-3.55 limited slip (F-150, F-250)
B6-3.73 limited slip (F-150, F-250)
If you put 4 oz's of FM in the rear, it's not going to hurt it. That's good stuff, I run a little of that in my trans
Yea the "8" is a radio code -
Radio Codes
8-AM/FM stereo with cassette, Premium Sound (Econoline, F-150, F-250)
7-AM/FM stereo with clock (Econoline, F-150, F-250, Ranger)
9-AM/FM stereo with cassette and clock (Econoline,F-150,F-250,Explorer/Mountaineer, Ranger)

Well damnit, I was hopeing I had a limited slip...thanks for posting that, I have been meaning to search around for a description of the door jam sticker codes.
So what is the best gear ratio for larger wheels/tires? Cause I noticed my truck sure seems to work a lot harder when I have my 35's on it than with my stock 17" wheels/tires. Which is of course to be expected, but since I do have the bigger 5.4L I didn't think it would have to push THAT much harder with my bigger wheels/tires on it. I mean, I get like 220 miles to the tank with my 35's on it and when I put my stock tires/wheels back on I get like 350+ miles to each tank. So that is a pretty big difference...So then I figured my rear end gears probably have a lot to do with it...

and it says 5.5 pints but with 3 quarts of gear oil and 4 oz of FM mine is still below the fill hole, I can feel it with my finger though, but it didn't come flowing out when I filled it up or anything so I hope that was enough...
So what does econoline mean anyway?
