just rtv for a gasket? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

lukecp · 12-11-2003, 01:04 AM

Unless its to cold this weekend, i am going to change the fluid on my dying 12-bolt rear axle for its last 80-mile trip home on Tuesday (pinion bearing is shot).
A member on another board suggested i change it so i might be able to get a few more miles out of it.

Anyway, i don't wanna pay $5 for a new gasket since i am only driving it an hour and a half or so, and i have tubes of blue, red, and black RTV in my truck. I usually coat my gaskets in RTV, but i have never used it alone before.

If i just use RTV, will it work without leaking too much on that short of a trip? Which RTV would be preferable to use? I'm thinking black or red...

Thanks for any help

We rarely use gaskets on diffs at work.
Although, we use The Right Stuff...if you are looking to get some RTV...this stuff rocks.

we dont even use the gaskets they leak anyways no matter what. just use some rtv. longhorn is right the stuff called THE RIGHT STUFF is real good stuff plus the can is charged so it comes out on its own. it will be in what looks like a caulk tube

Don't do that anymore. The RTV will break down the gasket, and it WILL leak. Either use only RTV or use a gasket with a little monkey snoot to hold it in place.
