diff

[97burnout]

So I was just changing my diff oil and I don't have any gasket sealer! It says in my haynes manual to use it with the gasket I have... This is important right. Now I am stuck till my friend can bring some by... besides that it is a cinch to do... On one other note have you guys I have some fluid accumulated and maybe dripping in front of the diff above the driveshaft... what could this be?

I've popped my cover off and put it back on several times without using RTV or a new gasket, and have had no leaks. And with the fluid on the front, that would indicate a leak in the pinion seal

Re: diff

so maybe I shouldn't worry about the rtv sealer... pinion seal is where the driveshaft connects to the diff right?

Re: diff

yea, the only thing is i would highly recommend not messing with that. To change it, you have to basically remove the pinion, and those have to be set to within a thousandth of an inch. Otherwise your gears will howl and fail prematurely.

Re: diff

I think it is fine. not leaking really just wet

Re: diff

don't use sealant. Don't worry about the pinion seal if it is just wet and not leaking. They all do that on our cars and will shortly do the same after replacement. I have done several properly by the book and they always still seep. Like said, unless you know what you are doing, leave that seal up to professionals

So your sayin that leavin the diff seal with a gasket is good enough... Yeah I won't mess with the pinion. I know how it works and understand that you can seriously mess it up.

Re: diff

Standard paper gasket can go in dry, no RTV.

Usually there's some leakage from the vent on top, that will be enough to make the housing "damp" looking.

Re: diff

gasket sealer never hurt anything, and theres no reason to start a job to not finish it correctly and completely

Re: diff

doing it correctly means no sealer^^^

Re: diff

Well I did just the gasket and it seemed to drip pretty good... so i ripped it off and used this stuff I had called form-a-gasket which I put on the gasket and now it isn't drippin.... This stuff doesn't get hard it just seals and stays gummy... seemed to do the trick... as for the pinion I am not concerned at this point. its normal... its a gm product.. "self lubricating" LOL
