hey guys.........needed to change my leaky diff covers. while i have em off i was hoping someone could tell me what i have in there.
the top pic is front diff, the bottom is my rear. i need to know if they are limited slip, blah......blah all that stuff. vile told me once if i posted pics u guys would fill me right in. would be soooo thankful. also how do u count teeth and tell the ratio? sure would like to find out while they are off. finally, whats the best way to clean it out and the gasket surface for reinstall? whats the best scenario for it to never leak again? money no object. hate leaks. thanks in advance guys.

Both are open, non posi

If you rotate the ring gear you will see some numbers stamped.  For example it may have 40/13 which would be a 3.08

Gasket scraper works best.  I have used RTV on my covers with no issues.

think i remember vile sayin lose the gasket, use the cheez whiz permatex. can u guys agree with this? what are the differences in the two diffs?
finally......what are those lil yellow things inside the rear? just wondering.

[zieg85]

Ditch the gasket for sure.  The yellow is either the c-clips that the axles are held in or the end of the axles themselves

i haven't used a gasket just clean it up with a rag and brake cleaner then use the "whiz"

[beastie_3]

Yup, I changed mine last month. The can I got was called "right stuff" or something similar. Wire brush, rags, and brake cleaner to get rid of the old gasket.

Everything everyone told you in here is correct! Use the right stuff. Personally I like to clean the area before removing the covers to avoid dirt from entering the housing as there is no filtering in there.

If you have access to air I like to use a small whizzer tool and scotch brite pads on it. A high speed electric drill would work as well. There is a holder with a shank on it to chuck into the tool. Then the scotch brite pad treads into it. Don't be bashfull about hosing it out good with a couple cans of brake clean. Parts cleaner fluid in a spray bottle works good too, then a final clean with brake clean.
 The yelllow looks like the end of the axles.
 As far the gears go either the last set of numbers on the ring gear divided into one another. Or count the teeth on the pinion, and ring gear. Then divide the pinion into the ring gear.
