Would someone be able to recommend a good video on how to change the rear differential fluid? I have a '13 GS 350 AWD F-Sport. TIA!
It really isn't that hard. AWD or RWD doesn't matter with the rear diff. Here's a decent one. One thing to always remember, get the fill plug out BEFORE you drain it.
Easy peasey. I like to raise the driver side a little higher to get more fluid out.
I used Red Line 75w85 and a cheap garden sprayer with the nozzle cut off. The fill hole is hard to get to unless you use a hook style pump or one of those squeeze bag containers.
Here's some parts on the 2013 GS350 AWD rear diff, if you're interested, a Toyota dealer will carry and likely be cheaper, but you need to give them part numbers as they usually can't pull up Lexus info. I recommend at least the crush washers, and the plugs if rusty.
Oil: 75W-85 GL-5
90341-18035 Drain plug(with magnet)
90341-18032 Fill plug(w/o magnet)
12157-10010 Crush washer (X2 need one for each plug)

new warshers and ready to install
Heck, I don't even put new washers on most of the time. The solid ones I inspect and sometimes drag across a piece of 220 sandpaper. The ones like that I just inspect and reuse. I've got 3 oil changes on my Lexus and 4 on my wife's Honda without changing gaskets and not a leak yet.

Same but I have never used sandpaper on it. Guess I just got lucky with my last six cars?

I had 60kmi+ on my wife's Elantra oil plug gasket. I'd just flip it every time. Her Santa Fe has 50kmi on the same plug gasket, I just flipped it. My dad's Camrys have about 250kmi combined with the same drain plug gasket.
I never replace them if they're metal ones, but I keep a new one in stock as it's possible for them to crack from getting so hard after work-hardening from compression, or just being a .50¢ part.
I'm currently flipping them on the Lexus. This weekend will be flip #4.

My last car, owned it for 7 years, and never changed the oil drain crush washer, never leaked. Metal washers probably lasts the driving life of the car.

Just think of all the landfill space we are saving, one washer at a time. LOL
I'd follow the service manual and just replace the crush washer. It's only a few pennies. In fact I just did my oil the other day and the drain plug was only hand-tight, even though I always replace the washer and torque to spec.
Not really sure what you stand to gain by not. Just add it to your cart at checkout, or get the fake

Since I do all my own maintenance, I know what I'm getting into. For my whole life of maintaining everything from lawnmowers to work trucks, I can count on one hand the number of drain plug washers I've replaced and have at least one finger left. They don't leak. Before washers were disposable, lots of cars didn't even have one. As a matter of fact, those particular crush washers look suspiciously like spark plug washers.
I've often suspected it was a ploy to get people to bring a vehicle in rather than do it at home since the washer wasn't commonly thought of as part of the oil change process.
When I bought my wife's Honda oil filters recently, they came with a washer shrink wrapped to the filters. I won't lie, I tossed it in the "maybe useful" tub.
