Got tired of dealing with the buggered heads on the drain plugs and ordered the hex ones from Toyota. Under 25 bucks for all eight and what a difference. This should be one of the first things everyone does when they get an FJ.

Which ones are the new ones? I can't tell by the picture.......................Ha!

You're right on- those allen head plugs make it so much easier.
 
Yet another "cheap and easy to do" thing I've had on my to-do list since I got the truck........12 years ago :rolleyes:

Didn't realize the drain & fill plugs are the same P/N. I should go ahead and just freakin do that when I change my fluids next.

Uses a 3/8" allen head doesn't it?
 
I didn't know those were available from Toyota -- Got mine from SOR... Wonder if the ones he sells are OE ? Not that it makes any freaking difference, but inquiring minds.

Nice thing about those plugs, you'll notice they're a bit longer, so they bite a bit more thread making them less likely to strip the soft alum case holes.
 
C-Dan sent me mine right after I bought my cruiser- with all the other preventative maintenance stuff.
 
i almost always replace the factory 24mm plugs with the magnetic allen plugs. i have actually seen the hex plugs come loose on the trail after hitting a rock in just the right spot. no chance of that happening with the allen plugs. i also run them on all my t-cases and some transmissions.

Please enlighten me. What is the benefit of the allen head versus a standard head drail plug? I see the benefit of more threads on a longer drain plug but is there more to it?
 
the only reason I do not like allens.. ( not enough to make me not want to buy them.. )
is that if you get someone who isn't familiar with them.. they can strip them .. or at least strip the first 20-50% if they are full of mud or dirt and you only get partial insertion.. and then give them a good reefing..

I didn't know they were so cheap.. I should get a few.. are these for diffs.. motors.. tranny's.. etc
 
advantages:

easier to remove than a 24mm hex style
rocks won't "loosen" them for ya

dis-advantages:

can fill with dirt ( so can the area between the welded on ring and hex bolt outer edge )
can strip if wrong tool is used ( then again, that goes for any type of fastener )
 
Six point socket works really well. I bought one when I changed the fluid on my buddies 4Runner. I'm sure it will work just as good on mine.
 
Buy a 3/8" drive 10mm allen socket when you make this change . It makes life a lot easier.

I use a section of a 10mm Allen key cut to a length that is about twice the depth of the pocket in those plugs rather than a socket. That gives me the option of using the key with an end wrench if clearance is tight. Otherwise I just slip the section into a 10mm socket....

I'm changing my clutch right now and thought I'd make the switch. Above you said "$25 bucks for all eight". Which other ones do I need besides t-case drain plug/ fill plug and transmission drain plug/ fill plug? I count 4...

Rear diff = 2
Front diff = 2
Tranny = 2
Transfer = 2

Just a suggestion, stash a couple of the old fill plugs in your tool box.
I've seen more than one diff plug fall out on the trail. It's good to have a couple of spares for yourself or someone else. I say fill plugs because they are usually in better shape than the drain plugs, if you have drain plugs that aren't to bugger up that would be better.

It's also a good idea for everybody in a group to carry a quart of gear oil. Individually it's not enough to fill a diff or t-case but collectively you usually have enough to get by with. In a pinch you can use motor oil.
 
Dumb question but looking at the invoice posted above, the OP bought 8 of the same plug and then 2 of one gasket and 6 of another.

It is the same plug for the fill and drain on the tranny, TC, and diffs?

Same plug for all eight but you need standard crush washers on the axles and transmission and alloy washers for the t-case.
