Poll: RTV vs. Gasket for diff cover

[Mastiff]

Kinda lame I know, but I'm curious what other people do when they pull/replace the diff cover.

 

[Chaddy]

I use Permatex Black RTV.

I just put mine on with permatex Ultra Blue RTV. Has not leaked in the 4 days it has been on and filled with oil.

I got it down to a science now after many redo's

Cover trimmed on the bottom so nothing hangs below diff , no peelbacks . Just the RTV marked for everything on the package front , the high heat orange stuff , set it up on the diff cover in a nice bead , push her on , tigthen her up , drink some beer and smoke for a loooooooong time , come back and fill her up . No leaks anymore

I've found using a gasket with Never-Seeze on both sides works well. This allows for multiple disasemblies using the same gasket. It's also much faster for asembly/disasembly time; No need to scrape and clean the gasket surface. I've never had one leak using this method

gasket with permatex High-tack on both sides.

Gasket for me!

I use only a gasket, no leaks on 5 trucks. I just spent 20 minutes cleaning old RTV off of the axle housing and cover on my new-to-me truck. I prefer the ease of the gasket. I also don't hit my diffs on rock very often .

I do the same.

Red Permatex. Run a bead around the cover and circle each bolt hole. Let it set up about 15 minutes. Put the cover on, wait another 10 minutes, then fill er up. Done it that way more times than I can count.

Black rtv.

Permatex The Right Stuff has NO setup time, so you can put on the rtv, install the diff cover, and fill it right away, good idea to take some of this stuff on the trails with ya

i use the orange high temp stuff, but i liked the idea about the gasket with anti-seize on both sides. im gunna halfto try that some times, sounds interesting!!!

i use the same stuff, on just about everything. expensive, but great product.

Black rtv, I have done it this way since I used to work for uhaul. Never had a leak on diffs I did

 

[4xcrazy]

I use a combination of the gasket with BLACK high temp RTV. no problems as of yet.

I do the thin coating of black RTV on the cover, then,then the gasket, then place it on the diff housing and tighten 'em up. Same thing with the trans pan, with great success.

I quit using that orange stuff long ago, i personally think it looks ghetto when it squeezes out and then there's orange crap smeared everywhere.

RTV... I prefer black but often all I have around is ultra copper.

RTV contaminates the gear oil but I don't care. It's not usually in there long enough to matter.

I use The Right Stuff also. And both diffs have a recessed drain plug un the bottom so I don't have to pull the cover as often (just a couple times a year to inspect the gears).

 

[colbystephens]

your poll doesn't have a naked option. that's against the rules! you could have at least said something like "rtv is great for sealing my nekkid a$$ crack"! SOMETHING. i think this thread should be deleted. just kidding.

anyway, i use the black or orange RTV - it all works for me. never had a problem.

 

[86k30]

i love ultra gray . my cover comes off so often that gaskets are hard to keep handy. always smashing the cover!!!!

 

[rcamacho]

I've used RTV for the last two diff's. Works fine for me.
