Dealer Used Red RTV on Diffs - Should I Be Pissed?
My front axle seals were leaking and replaced under warranty. When the dealer re-sealed the front diff, they used red RTV...
I'm worried this wont have the gear oil resistance needed for a diff application.
Permatex recommends their ultra black, ultra blue or gear oil RTV for diff application. I can't find any red RTV's online recommended for diff / gear oil usage. I previously used ultra black on it when I did a re-seal after the factory seal leaked when adding diff glide plates.
I have red rancho diff glide plates, maybe they thought they were being cute by matching with red RTV?
It would only take me an hour and a half to re-do it myself... Should I just leave it? What would you do? Yes I'm this anal about my jeep.

Why not call the dealer and ask why they used red vs black RTV ? I mean its under warranty let them fix it. Im sure you could ask for the black RTV instead of red next time its done.

I'd almost swear my 2008 came from the factory with red sealant on the diffs. I may be mistaken, but that's the picture I've got in my mind.
Eventually, mine seeped and they took care of it under warranty, but I think it was more due to sloppy and thin application than degradation of the sealant. My dealership did use black on the repair. It was at around 40k miles that they seeped, and only from isolated spots where it clearly was thinly applied. They were not dripping, though. Only seeping.

That's actually a topic for a hilarious new thread! I'm going to start it now. I'm sure you'll feel better after some of the stuff people post. Stay tuned!

When Dynatrac builds axles like the pr44,60,etc. they use red sealant also. I'm sure they know what they're doing. Maybe dealers have something different than what's commercially available in auto parts stores?

The red one is fine stop worrying about it.... My shop who specializes in jeeps(drives a nice built one himself) sponsors many events here in Ontario Canada always uses the red one.... No problems with mine for 5 years.

I don't know about diffs, but at work (I work on F-18s), we use red rtv on anything that sees above 500 degrees. There's always JP5 and oil in and around a lot of those areas and I've never seen that stuff deteriorated. If it can withstand JP5, I think it can hold up to gear oil.
