This is a discussion thread titled "DIY: Differential Oil Drain & Fill", within the Engine & Drivetrain forum, part of the Technical & Vehicle Assistance Forums category.
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.
