2010-2019 Lexus GX460 Rear Differential Oil Remove and Replace

It's that time again to change my rear differential oil. It gets easier each time!

[@gerardgunhouse397]

Bob I am a long time viewer of your GX 460 site and just wanted to say how much I appreciate the effort you put forth in order to make clear and concise service/ maintenance videos for your fellow 460 fans. Seriously, you do a fantastic job as I would not have tackled the differential/ T. Case service without your instruction. Of course, the icing on the cake is your irreverent sense of humor! So many you tube instructional videos are just boring, drag on and uninformative. Thanks for keeping it lite and for all you do. Cheers

[@GXBOB]

Thank you I appreciate the comments. It encourages me to continue to waste more beautiful Saturdays when I could be at the golf range.

[@Kiss__Kiss]

Great Explanation, BOB. Glad you ALSO explained, why you'd fill from one bottle to the next. The portion which you are NOT able to get drained due to the shortness of the tube. Meaning, it will not reach all the way to the bottom of each bottle. PS: Plus, the importance of torquing each bolt, and removing the Fill bolt FIRST.

[@GXBOB]

I have to admit, i get better with each video. You should see my how-to's back in 2018. I"m almost embarrassed.

[@gipstetz6720]

Great vid Bob. Excellent info. Thanks for posting.

[@GXBOB]

Thanks gipstetz

[@Henray316]

Thanks chu Hai. Hopefully you got some new jack stands. Those harbor freight might be recalled

[@GXBOB]

These were actually bought after the recall. But i'm not too worried. My religion allows me to be with 9 virgins in heaven if i die.

Thank you uncle Bob.

[@GXBOB]

Appreciate you calling me uncle but i might be younger than you…😂

[@AD-zy5gr]

Great job 👏

[@GXBOB]

Now I need a beer.

[@doctorwgca]

AMSOIL has a squeeze bag...... Super Easy for front and rear..... Had to use a hand pump for transfer case and ATF......

[@GXBOB]

Whaaaaat???? You realize the hand pump takes care of car maintenance as well as my daily work out. You should check out my biceps.

[@doctorwgca]

@@GXBOB LOL!!!

[@GXTOLX]

Thank u for wonderful dyi video. Saved me some moolah

[@GXBOB]

You’re welcome! ☺️

Thank you Sir, though they say it's not needed to be changed if you do not abuse it a lot in dunes or something.

[@pireina1]

Hi there. I am guessing no friction modifier additive is needed for neither front differential , transfer case or rear differential ? Just want to be sure so when the time comes for mine. Thanks for the great video.

[@GXBOB]

I don't know one single person that uses friction additives. Just stick w/ whats recommended and change it out at recommended intervals and you'll be good.

[@jchancalifornia]

Getting in, two of GX*bob’s videos before my wife tells me to get off my ass. lol.😂. I love the content and saving me money!

I have known to cause many rifts in relationships. Take care of your woman. 🍷

[@REALBanannaman]

My rear diff fill crush washer was missing, and the fluid looked decently clean. I bet someone changed it before but made a mistake.

[@GXBOB]

I’ve had that happen too without a single leak.

[@jinheu5119]

When you’re checking out the back your vehicle can you jack it up from your differential is a strong enough to get jacked up from that point

[@GXBOB]

@@jinheu5119 yes the center of your differential is a proper jack point.

[@H3LLZ]

Great how to video bob Can the transmission oil be change too

[@GXBOB]

yes it can, but i took it to my local mechanic because he offered a sweet deal. $80 for WS oil flush and fill. I couldn't say no.

[@tedlu008]

Wonder if it’s a good idea to use some locktite on the drain/fill plugs? Thanks.

[@GXBOB]

Oh good lord no. Factory torque with new washer and bolt is more than good enough.

[@tedlu008]

@@GXBOB sorry i meant threadlocker.

[@jinheu5119]

Hey, I’m wondering how come you you don’t use the Valvoline in the little plastic squeeze bottles is it easier to get it in?

[@GXBOB]

The store I purchased it from had limited options. If there were options that made my oil replacement faster and easier I would definitely take that route. I might even do an updated video. Thanks

[@jinheu5119]

@@GXBOB do you think those squeeze Valvoline bottles work well to do these changes?

[@mor235]

Hey GXbob. I noticed in for the 2011 GX460 it mentions in the manual that I should put in 2.85qt of diff gear oil and you used 3.5 in the video could we have different diffs? thanks

[@GXBOB]

Yo Yo Yo, i have never in my entire life used exactly what is called out because i always give a lot of wiggle room for overspills, do-overs, mistakes, angle of driveway incline, etc...if u know what i mean. In a perfect world, you're going to get pretty damn close to 3 quarts but my video did several shots and edits where i needed overage rather than underage because going back and forth to the auto parts store is a waste of time for me. Hence when i do my oil changes where it calls out for 8.2 quarts. i normally just buy 9-10 just in case. The over 3 quartz you saw me do doesn't ruin your differential since you know when to stop once you see the overspill and whatever you have left over is good for the next fluid change.

[@mor235]

@@GXBOB sounds good, thanks for the advice boss!

[@rohankrishna95]

Hi Bob, what are your thoughts on hydraulic suspension oil replacement? According to Lexus, it should last a lifetime but Is there is such thing as lifetime fluid/oil? Mercedes ABC failure was caused by lifetime fluid. I have 95K miles on my 2014 GX Lux. Should I change it now, is this a DIY job? Can you please make a video about the type of oil we should use and how to do replace it?

[@GXBOB]

It is a lifetime for a reason if i think you're talking about what i think you're referring to. The hydraulic oil within the system and lines to ensure the suspension is working properly. To be honest, i wouldn't even bother. The worse that can happen is your airbags go out or the sensor fail. Both are replaceable. Not one time have i ever heard anyone do maintenance on the hydraulic system oil before and for good reason, there is no history of failure on the GX. I replace the components when they fail. Not because the oil caused the failure, its because the components have a "life" span. It will fail.

[@rohankrishna95]

​@@GXBOB Thanks for the quick response.

[@GXBOB]

@@rohankrishna95 Not sure if i answered your question, but it's an area that is not visited that often to find an abundance of "material" to read about.

[@Jantonvid]

Lexus charges 600 to do a bleed, fill, and repressurization of the KDSS system. you need a special tool that Toyota and Lexus has as the PSI is crazy high

[@rohankrishna95]

@@Jantonvid My brother has a 2005 LX 470, at 240K miles some light came on which indicated that suspension oil needed replacement.

[@oozlovervdxp]

Man that oil is still fresh. How many miles?

[@GXBOB]

77k...yup!

[@oozlovervdxp]

@@GXBOB not sure if I missed it. But you should mention the recommended intervals on the maintenance. Great video dude

[@GXBOB]

@@oozlovervdxp Thanks, i need to remind myself also!

[@nyclatinband5162]

Hey Bob great video. I have a question. I have a 2014 Lexus GX460. Toyota/Lexus recommends to use a gear oil with the viscosity of GL-5 or equivalent. I want to change the gear oil on the rear and front diffs as well as the Transfer Case. I bought the Mobil 1 Synthetic 75w-90 LS. Is this equivalent or better that the Toyota GL-5 75W- 85 for the diffs and the Toyota Transfer Case Gear Oil LF 75W?

[@GXBOB]

To be honest with you, If i had money coming out of my ears, i would pick everything OEM Lexus/Toyota. Only reason why i chose Mobil or Valvoline is because i confirmed its equivalence and its much cheaper. I've used Mobil 1 since the times of dinosaurs and it hasn't done me wrong, so.....yeah that my best answer.

[@nyclatinband5162]

Thanx brother. Keep up the good work with the videos.

[@bencti4851]

How often should we change the differential oil?

[@GXBOB]

Start on page 48. Use control +F and type in differential. It should fast forward to all your differential oil schedules. drivers.lexus.com/t3Portal/document/omms-s/L-MMS-13GX460/pdf/MY13%20_Lexus%20GX%20460_WSG_lr.pdf

[@cheneybros]

Would you think using 80w-90 would suffice?

[@GXBOB]

I'm going to use what i'm going to use as listed in my videos. If you want to use alternatives then there are threads after threads of debate on Lexus and ih8mud forums that can answer that for you. i'm not in the business of comparing oils and keeping a truck 5 years to see if there are any improvements that come out of using a different weight oil. Thats like watching paint dry to me.

[@JianningXu1988]

What was your mileage when doing this diff oil change?

[@GXBOB]

I believe 75ish thousand. Here is a good link to follow. At the drop-down menu, click on 75k. I usually do the ones under "special driving conditions" at the bottom because i tow a boat and a travel trailer often. The differential, transfer case, and tranny are the first fluids i change every time i pick up a used vehicle because i have to assume the previous owner didn't care to. drivers.lexus.com/lexusdrivers/service/maintenance-schedules

[@JianningXu1988]

@@GXBOB thanks Bob

[@new002one]

Thanks for a great video with detail explanations especially the torque specs. But I will never jack up a truck this heavy on my sloped drive way. It’s a big safety hazard. Also harbor freight torque is not accurate enough to use for these bolts. I recommend invest in a good one for those types of jobs

[@GXBOB]

Thanks for the advice Machlob. Now that I’m not entirely poor anymore i was able to replace all my torque wrenches with semi-decent ones from Husky. Thanks for joining us.

[@mikejohnson9118]

Folks always wear eye pro due to the "splash" factor. Bob just forgot to wear his. (He is old)

[@GXBOB]

Only sissy's wear protective gear. Real men risk their lives changing oil.
