Good post and photos but I noticed it says "Use LSD Oil only" on the case and you didn't say Limited Slip Differential oil in your parts list. I know my truck has a LSD but some regular 2 WD owners might not know this.

That's because the royal purple oil has friction modifiers for LSD in it already.
Just did my 30k change of the front, transfer, and rear. I tow every weekend 8 months of the year.
The rear was definitely in need of a change, but the front and transfer were actually fine. I put 75w/90 RP in the front & Transfer, 80w/90 and the separate LSD additive for the rear I bought at the Toyota dealership, next time I'll just get Lucas 80w/90 and only buy the LSD additive from the dealer.
Tips on changing the front differential: Buy a 1/2 inch diameter by 12 inch long piece of pipe from home depot to slip over the 10mm allen wrench so you can break them free easily. Also, I ran a tube from the top of the engine compartment down into to filler hole so I could easily pour it from above.
I just had my local shop change the oil in my 06 DC LSD. They said they could only get 3 quarts in. I know they didn't run the truck around the block to disperse the oil and then top it off. Before I double check the oil level, is there any danger to the LSD if the specified amount of oil is not there? Like a 1/2 quart low.

I bet they had 3 bottles of gear oil and used what they had. . The lack of oil may cause the rear diff to overheat, and increase the speed of oil break down. Chances are it will be fine, they got at least 81% of the oil in there. You may want to listen for shatter back there. If you hear some odd grinding noise, you can just add some friction modifiers from the dealer. Not very costly and you won't need any special tools to put it in. Just need the right socket to open the fill plug.

Thanks for the reply! I neglected to mention that I supplied four quarts of Royal Purple to the shop and they gave me back the fourth quart. Hopefully, the quality of the oil will save it until I can get it topped off if it really is low. I won't be driving it many miles until it's checked out.
Got 30k service and rear diff. started making noise. I took it back to the dealership and they told me they forgot to put LSD additive. 3 weeks later it was still not resolved and I took it back. They test drove it and said, they didn't notice anything. So I took matters into my own hands and put Royal Purple in. After opening the fill bolt nothing dripped out, which tell me it probably wasn't filled all the way. Thanks to this post all my issues with the rear diff disappeared. Thanks guys.
just did this last night after about 55k miles since its been changed and it's a piece of cake. i used lucas 80w-90. i only had 3 quarts, so i had to drive around 30 miles total to find another bottle. i have it all topped off now though..
ive actually done this before also. the first time i did it, i had gone 100k miles. It was black. my friend who works at jiffy lube and i did it together, so we used clean oil to actually flush it out. this has got to be one of the most overlooked things when it comes to diy maintenance.

I have changed mine a few times and I am surprised that more of you are not adding a LSD additive. I use Lucas or equivilant high grade diff oil, and if I don't throw in a bottle of additive I get a chatter in the diiff every morning. It seems to go away for the day, but in the morning when I back out of the garage, it chatters. Put in the additive - gone. Using 80-90W as I can't find 90W as the manual suggests.
When I was adding the fluid to my front diff I would squeeze in as much as possible with a piece of fuel hose pushed onto the end of the bottle tip. When I couldn't get any more out of one bottle I'd move to the next one. Then I'd start combining bottles so I'd have enough in one to continue squeezing it in. I had no trouble getting the front diff full with the limited space, and no spills. Then whatever I had left over in the bottle I couldn't drain completely simply went into the easier to access transfer case and rear diff. And I used Mobil 1 75w-90 full synthetic for LS in the rear and Valvoline 75w-90 in the front and transfer case. I'll probably be switching to Mobil 1 for the front and transfer case as well since I noticed a slight "pop" noise or jump in the drive train when switching from 4wd to 2wd in some ice and snow with the OEM fluids. I had done the front and transfer case first and then the rear LSD later.

Thanks for the great write-up w/ pics helped out alot... I just did this to my 06 DC Tundra 4x4 w/ 11000 miles on it...and boy did it need it... the oil shimmered from all the metal in it, and the drain plug had a big glob of "metalsand" and some pieces of metal on it. I am kinda worried about the amount of wear for such little mileage... but I do alot of towing and heavy loads when I do drive the truck. I will look into doing the Transfer case and front very soon. I used Mobile 1 LS 75w-90 SAE 90. I also could only get three quarts in before driving it around the block and then the 1/2 quart went in just as described.
Hey guys,
Need a little help here. I just had a shop put new 4.56 gears in my 02 AC 4x4. I am now passed the break in period and crawled underneath to swap out the fluids. I noticed the front diff was leaking a little (not enough to drip to the ground, but definitely a slow leak). Then I noticed the T-Case is doing the same thing. Before the gear swap, I had no leaking. What do you think could be the problem? Did the shop overfill maybe? Not properly sealed? Why the T-Case? He didn't touch that.
You think I should go ahead with my fluid change? Or hassle with the mechanic that lives 1 hour away? Thanks!
