Topic: socket size for diff drain plug???

[usmcab35]

i just got everything to change the fluid in my diffs but i dont have the correct size socket and am off to get one... do you know the size?
 

[jimbo74]

15/16" socket

use a 6 point socket to avoid rounding as much as possible, a 24mm socket will work as well, but it isn't as good a fit/a little bit sloppier than the 15/16"


also, make sure you get a thin wall socket, the thick impact type sockets may not fit into the round recess around the plug

@ that time, I would also upgrade to the upgraded drain plug style, it's OEM on later Toyota trucks

i got a 24mm and it worked for the front and then i moved to the back, drained it and then realized that the previous when redneck vice grip on the fill plug, so the socket is useless...

[jimbo74]

were you able to remove it? if not, try a chisel and a hammer, i have always had luck using an air chisel

[usmcab35 [OP]]

havent got it yet, going to get a different one from the yota yard here tomorrow, and then try a vice grip or something, i dont have any air tools though i wish i did.

u can always weld another nut on too..if u have a welder that is

[usmcab35 [OP]]

my welder is in the mail, so if i cant get it off any other way ill just have to wait i guess

[jimbo74]

u can always weld another nut on too..if u have a welder that is

everytime i have tried that, it never works, i jsut end up snapping the nut off.....

air tools have been the only way that have ever worked for me... you could also jsut try a manual chisel and a hammer, will take longer but should get teh job done

[usmcab35 [OP]]

thanks ill give all the ways a try and ill try to get some way to try the air tools

[usmcab35 [OP]]

hey jimbo you said that they plug up above in the pic is oem on later years? what years? because if i can i will try to get one of those instead.

I hate the factory plugs on the diffs and bottom of the tranny and t-case.  Way too thin and easy to strip.  The replacements Marlin sell are 100X's better than the stock ones. 

[usmcab35 [OP]]

I agree. well 1 bfh and 1 huge vice grip tightened with a allen wrench and a few busted knuckles and its off. It was really on there. replaced it with a magnetic drain plug instead of a fill plug, got it at the yota man for 50 cents...

[jimbo74]

the oens marlin sells are the stock toyota ones found on later year trucks... hold on, i will try and find the part numbers..... i am not sure what year they are on

[jimbo74]

#90341-18021 drain/fill plugs

#12157-10010 aluminum crush washers

there are steel washers available and im looking for the part # right now, i have used the aluminum everywhere and never had a problem with leakage though

Aluminum washers are designed for transfer cases, and aluminum transmissions (G, W & R series). Steel washer is designed for axle housings and steel transmissions (L series).

marlin sells these for $4 per washer with plug, and that isnt a bad price, it is about what the dealer charges for the item (not sure if marlins are steel or alloy washers though)

however i order them in bulk from an online toyota places like www.trdparts4u.com or www.1sttoyotaparts.com or www.toyotaoffroadparts.com and it is a lot cheaper

[jimbo74]

#90430-18008 is the steel
