What size allen/hex type wrench do I need for the front differential drain plug? I already have the right one for the fill hole, but the drain plug requires a larger one.

I just finished replacing the brake fluid, rear diff fluid, oil change, went to mt-90 on my transmission, fuel filter, coolant and am left with the front diff and some grease. did I miss anything for my 140K used 4runner I recently purchased?

I used regular oil 75w90 in the rear diff, and am going to use 80w90 in the front diff. I am not sure what to use for the transfer case? Any suggestions? I still have 1.5 quarts of redline MT-90, can I use this for the transfer case?

 

Be sure to grease the Zerk fittings for the u-joints and slip yokes. There should be one for each u-joint and one for each slip yoke, six in all. The slip yokes can take several pumps each. The u-joints should get one pump or a partial pump until old grease begins to squeeze out past the seals. The service manual recommends you grease these at each oil change

Toyota recommends NGLI-2 grease with moly disulfide for the slip yokes and plain NGLI-2 for the u-joints. Valvoline makes a synthetic NGLI-2 grease with moly disulfide that's easy to find. I've used it for all Zerks for years with no problems.

Sorry, can't help with the size of the wrench for the drain plug.

 

Ditto, it's all in there regarding diff fluid changes.

 

Yep, nice site thanks! The local auto shop told me 75w90 for the rear and 80w90 for the front which is opposite of what this site says??

 

Should be a 10mm or a 12mm depending on your set up, some trucks have different sizes.

 

Unfortunately, they are mistaken, the site is correct.

 

This is the best writeup ever. Thanks to this, I am 100% synthetic, and it took no time at all.

 

for anyone doing a 1995 4wd sr5v6 3vze pickup, all of the plugs use the same 24mm socket, which makes it really easy to find them and know you're opening the right things.

 

Awesome. Just what I was looking for!

Jamie you stud! I saw the honorable mention at the bottom.

 

yep, 24mm socket for everything but the front diff. The front diff has 10mm fill and 12mm drain plugs. I put the mt90 in my tranmission and transfer case. I will throw some 75w90 in the front diff next weekend when I get myself a 12mm hex tool.

So should am I ok with the 75w90 thats already in the rear diff, does it really matter here in san diego? The weather is always hot.

 

Thanks, but I'd say Bob was the real stud for doing the writeup.

 

Bob_98SR5 did a great writeup on this. Everything is there if you just look.
