No problem, you will also have to take off the weight dampener to get to the fill plug.

Appreciate it man. Any special tools for that? I didn't see anything special blocking it during a quick peek.

Dampener is attached to the subframe via an E12 torx bolt. Torque spec is 21 ft lbs.

You can avoid removing that damper if you use a low profile allen key on the differential fill plug.
If you take this route you'll have to figure out how to torque that plug to spec.

Thank you.

So when the oil temp sensor is removed the fluid pours out? Is there a torque spec to reinstall it?

Yup. 10 ft/lb. Basically a little more than hand tight.

Does anyone know what the part number is for the OEM gear oil? Or if it needs an additive for the limited slip differential?

I will be doing this change as part of my winter maintenance.

That’s all you need to know. It’s super simple. Unplugging the sensor and filling up the diff is the only difficult part about this.

Yeah, no worries.
Unplugging the sensor was the only tricky part. I didn’t wanna break the tab. But you have to press pretty hard. (At least in my case)
Just make sure you have a pump to add the fluid back in. Fill until it comes out the hole. And reinstall everything. Super easy.

I have a PDF from Toyota that's over 1000 pages (I think) with DIY instructions. I can send it afterwards today
