Changing differential fluid - A step by step "HOW TO"

All fluid capacities are in your owner's manual. It's almost like Toyota thought you might need this information at some point and created a handy reference with it all in one place...

 

Thanks for the response...

 

ahahahahah...nice one Be easy on the guy

 

So this may have been covered, but with Royal Purple oil you DO NOT need any additives for the LSD correct?

To change both differentials and transfer case you need:
1.1 QT

$29 75W-90 Synthetic Gear Lube - 1 Quart (Pack of 2)

75W-90 GL-5 (transfer case)
1.6 QT 75W-90 GL-5 (front differential)
3.0 QT 75W-90 GL-5 (Rear differential with LSD)

So if I just get 6 QT of 75W-90 GL-5 Royal Purple I'll be all set to change all 3?

 

if you have a LSD you need LSD additive. And yes 6 should be good.

 

Ok so tomorrow I think I am going to try and change out the my diffs oil. I saw that royal purple was getting some good feed back through page 6 of this thread and I didn't feel like reading the other 15 pages. So if you have put RP in the diffs, could you all let me know what you think so far and where is the best place to buy, store or internet? THANKS!

 

lol

 

Found this in my rear diff...



Thats what flowed out of the fill plug when I opened it to check the level. Looks the same in my transmission. Think I should change it? lol

 

nice. probably glad you changed it now huh.

 

Oh yea. Changed it with some cheap Wal-Mart gear oil and Im gonna change it again whenever my 8qts of Amsoil Severe Gear

$29 75W-90 Synthetic Gear Lube - 1 Quart (Pack of 2)

75W-90 comes in. Gonna change everything.

 

So i am waiting for my next paycheck to buy a buncha Amsoil oils and stuff but i was under the truck the other day doing the diff breather mod and i have the LSD oil only stick on my rear diff!!!....why is this? i dont have a TRD Sport or Offroad.

does this mean i need some addative now? and do Amsoil make that as well? (i am buying so much stuff the rep i know is giving me a killer deal so i wanna get it from him at the same time)

 

I had the off-road edition, all i put in so far is the 3 qt of amsoil 75-90 gear oil... so far so good!

 

Redline works fine so far with my LSD. No chatter and works grabs just as well as with the factory oil! Ask the rep if the friction modifier is in the oil already. Redline has the modifier already in it.

 

hmmm thats interesting to know...if i still go with the amsoil how would i know if i get chatter? what does it sound/feel like?

 

ok...thanks chris!!!

 

1. dont bother with the hose for the bottle of gear oil. I tried it and managed to get he bottle to explode all over me as I got gear oil in my eye, up my nose and in my mouth. Gagging, blowing my nose and blind... I made it to the sink. At least it was fresh oil. Just squeeze in what you can, and just put the remainder into the next bottle. You can get almost al of a bottle out sans hose wit the rear diff. so maybe do that one last.

2. Rear diff. DEFINITELY take the tire out. Makes life SOOOO much easier. Oh and if you waited 60k miles to do the rear diff and the fluid is more like a black toothpaste you may wanna do what I did to get the most out of your$10/qt mobil1 gear oil. I ran back to the store and got the cheapest stuff they had (Coastal) and threw that in for a few miles around town and then drained it and put the Mobil 1 in. I kept the Coastal in case I have the same issue in the front.

Did the tranny yesterday and plan on doin the front diff and the spark plugs tomorrow!

 

That's a good idea for those that are negligent in their scheduled maintenance , flushing it out with the cheap stuff. I'm going to keep it in mind in case I am derelict in my duties.

 

great thread...gonna do it next weekend. time to collect the stuff i need. last time i did this job, it was on a chevy, without a drain plug. i made a mess out of my MIL's garage. no brownie points that day.

i got a locker, so i will try to find the royal purple, or just go with the dino stuff..i plan to stay up on the upkeep, so i will change it regularly..
