Diff fluids poll

Hey I was wondering how often you guys change your diff fluids?

 

I changed both diffs & transfer case at 45k with synthetic.

 

Needing to do this on mine. Bought at 48k, doubt it has been touched. According to the dealer, they only deal with anything that's presenting itself as a problem with driveability so I know that they completely ignored it during their "certification" process. Hell, they left fucking autolite plugs in the thing so I know the diff oil wasn't touched. Interested in what folks' opinions on gear oil are.

 

I can't really vote because mine has 27K miles and I just did the first change to mobil 1 last week.

 

Rear - 15k dumped it for the 1st time...not bad. I'll go 25k intervals now on that.

Front will be 50k

 

Did the rear a few weeks ago as part of my 30k mile maint. I chose 25k in the poll.

 

I cahnged my diff at 30k, used royal purple in all three. I will change it at 30k thereafter due to my lack of offroading.

 

Every 30k like the book says.

 

those of you using Royal Purple, its 75w90 for front and rear right. And max atf for the auto tranny. also I read you dont need the LSD additive with the RP, is that true?

 

Same here. I'm sticking with what the book says. I still have about 5,000k to go until I hit 30k but I already purchased all the diff oils and LSD additives. Oh and I am going to change it out with redline synthetic and redline LSD additives.

 

I changed mine at 30,000 so I chose the 25 poll.....switched everything over to amsoil synthetic diffs, transfer case, and MT90 in the tranny. Probably wont do it again until 100,000 now unless I submerge the axels in water or something

 

me too

 

do the first at 15k and what ever your preference after that i myself will do it every 15 remember the manual's always base there intervals on ideal driving conditions.so if you live in hilly and a place where your roads aren't stait and also stop and go driving you will need to do it more often it all depends on driving habits and terrain

 

30-40K Only Use RedLine Diff Oils. and MT90 for the Man Trans on the Tacos!
and this is Why, Awesome Shock Proof Oil!

 

im just about to do mine also in my TRD off road, since i the e-locker i dont run the LSD additive right.

 

Correct, Just 75W90

just make sure you use good Oil.

 

5 years or 50,000 miles. Whichever comes first. JMO.

 

30k with Redline 75w90

I just had my local mechanic (not Toyota), whom I trust, handle my 30K maintenance because I am jammed up at work and going on a vacation road trip next week.

Toyota has two different 30K servicing options: one for heavy use (towing & 4 wheeling) and one for light duty use (road driving). The heavy use calls for diff. oil change, transfer case, and tranny coolant. The light use plan doesn't change out the oils or coolant.

My mechanic said mine looked fine, since all my use is light duty city and highway miles. So if you are doing it yourself its a judgment call as to when you change it out, but its definitely not a given to do it at 30K. I will probably change mine out around 50K, well before the 60K servicing mark. He did clean out my intake, which is something Toyota doesn't offer in their 30K maintenance, but is beneficial.

Between the servicing, the full detailing I did the previous week, and the brand new Bridgestone Dueler A/T Revos, truck is looking and running sweet.
