Just today changed lubricant for my 2008 T4R 48K now; the Front & Rear Diff and the Xfer Case. Thanks for all the info on the threads here everyone.
I believe Toyota says 30k to change fluids. I put in Amsol long life synthetic lube, will prob go to 50k but not the 100k they say, I mentally can't picture me going that far without changing lubes.
Tips:
As advised, I made sure to have the upper bolts open first then lower to release fluids. If I cant refill it, dont drain it.
Wear gloves- had leather ones- the bolts are on tight. I bruised fingers getting them open when didnt wear the gloves and its better to have lube on ur gloves then ur hands.
Have your 24mm socket for Xfer case and read diff bolts. Need a 10mm hex key for front Diff bolts. - AFter lifting truck on jackstands I had to run to sears to get the 10mm hex and a 3 n 6" extension for 24mm socket. Thanks honey for being home with the car.
Bought a new pump to pump fluid in. Thank god new lube is not as thick as old gear oil thats hot was molasses!
Put on e-brake, used jackstands, put blocks on rear tires.
Pretty similar to changing them on my 2000 Jeep Grand Chkee.
Front diff n Xfer case color not bad. Rear darker but still not bad color wise. I think its crazy but know of some who up to 100k have not changed their fluids.
Also used a small pipe to put on 10mm hex key for more leverage and power to open bolts.
Combined about a half a day of work - going to get parts thru til putting tools away.
Thanks again all here for your previous posts to help me with this.

Sweet. I want to do mine in the near future. Hopefully with next oil change. What is good/bad color for the fluids?
 
pump

Do you have to use a pump to put the new fluids in? How much did the pump cost? I need to do this soon on my T4R.

Pete,
Most chain auto parts stores have them for $6-$12. The Ace Hardware or Marine store will have something that'll work too.

I find that it's worth saving an empty bottle or two that fits the pump perfectly. Sometimes some bottles fit well, some don't. I will transfer new product into the 'good bottle'.

TIP: Especially with gear oil let it sit in the sun a while, it pumps easier warm.
 
Good info. In NY it was 80 degrees on Monday so fluid ran out and in with no prob- no warming of fluid necessary. Color was kinda like clear -coffee with milk I guess, lite brown for front n xfer case and brown for rear diff - thank god not dark brown or BLACK like some others have said.

I got my pump at the auto parts store for $15. Pump fluid out of orig container into pump then push fluid into case/diff. Not too bad just remember when taking tube out of oil quart to point it up so lube dosent leak out. It's a messy job have rags handy and I used an old sheet to put on driveway to soak up fluids.

Truck is smoother running now BUT I also just did a CAI and new plugs a week ago so overall its running GGGRRREEEAAATTTTT!!!!!!!!!!!
:lookout:
 
I used a pump that is designed to change outboard lower unit oil. You can buy them a Walmart, Academey etc. They should be less than $10. and screwed right on the gear oil bottle.
 
I am doing an oil change and greasing the drive shafts this weekend. Next weekend I am planning on doing my front, center and rear diff fluids. There is a great write up on here which I bookmarked. Very straightforward with pics too. I have all the tools, just need to buy the oil and I think I might get a pump too since others suggested it makes refilling easier.
 
I see the first time might be the 30,000 service. It is listed as 'Additional Maintenance Items for Special Operating Conditions'. So do they usually do it, or only if I saw I 4WD a lot?? I am guessing they do it just to charge you.

It's kinda up to you to make sure it's included. I (this is me not Toyota) highly recommend doing both axles by 30k or earlier with synthetics. I also like to include the t-case. After that a (with synthetic, IMHO,) a 60k interval is ok.
