Differential and transfer case fluid change interval based on Toyota/Lexus recommendation

[SWUtah]

Did they disclose what brand of fluid used?

Lexus dealerships close to me use Kendall for differentials. It is made by Phillips 66.

It’s Kendall I’m sure because they use Kendall oil 0w20 in the engine very high in titanium good stuff.

I have had 2013 lx for about a year. I purchased it from Florida at a bmw/mercedes dealership with 86,000 miles. The lx was serviced at the lexus of jacksonville. So, I added the vin number on lexus owners website. It showed service every 6,000 miles. The ahc was serviced at 60,000 miles. The differential, transfer case, and transmission fluid was not. I took the leap and purchased it.

So, having owned acuras i was bit concerned. Acuras mdx differential typically require fluid changed at about 10,000 to 15,000 for the first change then every 30,000 miles. Transmission fluid is every 30,000 miles with a drain & fill and transfer case is about the same.

I immediately had the transmission fluid exchanged.

I called all the lexus dealerships in my area. There are four of them. Not one of them used the 75 w toyota transfer case fluid.

I purchased the 75 w toyota transfer case fluid at (2) $58 a quart. I also purchased mobil one 75 x 90 differential fluid.

I also purchased the
GENUINE TOYOTA GASKET KIT FOR TRANSFER AND DIFFERENTIAL SERVICE

Amazon product ASIN B017V4BAXI
I used independent mechanic from this forum under my state. He has stated that fluid looked clean and no metal shavings. I asked him if there was any evidence if the fluids had been changed. He said no. He stated that Toyota has excellent quality control. My fluids didn't need replacing. He charged $57 for labor.

What is this “lexus owners site” where I can see service history by VIN?

You can register any VIN number and it will allow you to see the service history performed at the Lexus dealer. I did this before buying my certified 2018 LX to ensure that the vehicle was serviced timely.

I changed the front and rear differential fluids, and transfer case fluid about 11,000 miles ago. I used Valvoline SynPower Full Synthetic 75w-90. We had the rig on a lot of 4x4 roads this summer (Montezuma, Ouray, Lake City) and the 4x4 system worked great. Sometimes the drive train can be a bit fussy going in and out of 4 low but this is due to something else.
