Rear Diff FIPG or paper?

[weekendclimber]

Just wondering if this can also be used for the rear differential gasket. Getting ready to get the new 3rd member in and debating on whether to order an OEM paper gasket or use this. This is the FIPG used for the cam seals and half moons on the valve covers.

I would use FIPG over paper. However, I've always used Permatex Ultra Black on diffs.

I used HondaBond but that’s just me. I realized later that Lube Locker makes a reusable gasket for this application. That would be my first preference.

Is that the LLR-T080? I might go that route if this stuff isn't going to work.

I wouldn’t use that one that’s meant for oil don’t know if it will hold up to gear oil. Toyota has one that’s specifically for gear oil that is used for the transfer case. I’ve never had an issue with the actual gasket.

That's pretty much what I was thinking. May do a lube locker or just plain old permatex ultra black. I don't foresee digging back into it for a long long time

That's what I use. My rear diffs been in and out 3 times in the past year. I've never seen a drop of gear oil after letting the Ultra Black cure. I use a thin layer on both mating surfaces. Mount the diff and hand tighten the nuts. Wait 2 hours. Come back and torque the nuts. Wait till the next morning and fill up the diff.

You are correct. You don't want to use the black for transmissions, transfer cases or differentials. You want to use the orange/red colored FIPG.

I'd personally use the Toyota FIPG over other sealants or a paper gasket.

I agree. Local parts store should sell a rtv specifically for differentials. It’s by permatex. It’s grey color. I used the Toyota red stuff. And I honestly didn’t like it. It never cured. Using permatex differential rtv. It’s great!

I used Permatex right stuff (black aerosol can stuff) when I installed my new/used diff with the Truetrac in it.

Hasn't leaked a drop. The only catch is it sets fairly quick (which is why I wanted to use it).

FIPG would be my next vote.

Can't remember what I used on mine but it was blue in color. Still dry as a bone 3 yrs later.

+1 on Lube Locker. Just tried it for the first time and have been very pleased.

interesting, I ordered a new actuator for my front diff and sealant from camel back. I did not have a part number for the sealant so they sent what was "needed". Installed 2 years ago ? no leaks, they sent me the black

I would order a paper gasket from a Dealer for this. That's what the 4Runner came with from the factory so that's what I would put back in it.

I'm thinking maybe 13ish for the cost....

Thanks for all the tips everyone. Since I'll be doing this on my own, I think the best option will end up being the paper gasket. I can just hang that on the studs and slam the 3rd member home. Been reviewing all the [MENTION=120071]mtbtim[/MENTION] videos as well, since I'm doing my rear axle seals at the same time just as preventative maintenance.

[MENTION=116195]weekendclimber[/MENTION] Toyota dropped a new paper gasket in there when all the axle components were brand new and fresh out of manufacturing. All the mating surfaces were perfect.

You'll probably use some type of abrasive to clean up the surface where the old gasket comes off and there's a good chance there will be or you will create some slight imperfections in the surface causing the seal with the paper gasket to be less than perfect. This is where the FIPG comes in handy. I've personally had to pull 2 diffs and a transmission due to paper gaskets not sealing on the first round. Not saying its not possible, but IMO just use the FIPG. I'm the Parts Manager at a Toyota dealership and all of our technicians go straight to the FIPG when doing these types of services for that very reason.

Yes you can. Been there don’t that. Put the RTV on the axle housing. Then you slide the 3rd member on. It’s jot easy but I’ve don’t it alone more then 3 times.

Paper gasket would be my last choice. It's more like a controlled leak than a seal. Modern FIPG like ThreeBond, HondaBond, or Toyota FIPG works super well.

This is a good explanation. You've changed my mind on this. Since I've already ordered the paper gasket, I may just FIPG the housing side and stick the gasket on that and FIPG the 3rd member side and squish them together. Any thoughts on whether this would be better/worse? Maybe I'm overthinking this?

I watched you man handle that sucker in there on [MENTION=120071]mtbtim[/MENTION]'s video. What are you, about 6'0"? I can probably Hodor that in there too ray2:
