What have you done to your 2.5 gen Tundra today?

The rear diff plugs are pipe thread no crush washers

 

Ok so no gaskets at all are needed?

 

Mine are not pipe thread and they have the OEM crush washers, P/N:

$14 12157-10010

12157-10010, installed on both the drain and fill plugs. I actually need to buy two more of them so I can replace the differential fluid at the upcoming 90K mileage point.

 

you might be thinking of the transfer case

 

My Tundra is 2WD. I'm certain of this.

 

What’s the mpg? Obviously you’ve got a lot more effecting it but…

 

Correct; same as transmission

edit: the transmission from 07-21 uses the same crush washers for the drain plug & check plug across the entire year range

*not that the transmission uses the same crush washers as the diffs*

 

I lost exactly 20 lbs going from those factory 20s on 35x11.5 to 18s on 35x12.5 , so you should have definitely come down some

 

Correct

$14 12157-10010

12157-10010 crush washer x2
for rear differential drain and fill plug

 

I'm seeing

$10 35178-30010 luxlead 20 PCS Transmission Drain Plug Gaskets Oil Crush Washer Seal Rings Compatible with Toyota Lexus 4Runner Sequoia Tacoma Tundra Lexus GS450H, IS250/350, LS430, LS460, Replaces 35178-30010

35178-30010 for the trans drain and check plug gasket and

$14 12157-10010

12157-10010 for the rear diff drain and fill gaskets.

 

Sorry, I meant that the transmission from 07-21 uses the same gasket… realizing now the word phrasing was terrible

 

14.5 mpg in the summer, 14.1 mpg in the winter on average. I have the 4.6 so its a little less of a gas guzzler than the 5.7. But not bad considering I have full skids, bumper, sliders, camper, etc.

 

thats very good with everything plus the tent; is that highway driving or city?

 

I did mine the other day at 30 degrees, you win this one!! Awesome truck, btw!

 

Howdy made a small post forever ago, but since then I have done a lot to my 2015 SR5 CM.


^How it looked for a while when i got it in November 2025.


^ How it looked in January 2026 when it snowed in GA. I added Auxbeam fogs, Auxbeam switch 6 gang switch panel, Amazon special chase lights, and ebah special paint matched grill and bulge after the oem one decided to come off on i985 when i was headed to work.


^ And how its its now. Got some new wheels and tires for it. Black Rhino Rapids in Midnight Blue 17x8.5 and got them wrapped in Yokohama Geolanders At4s in 285/75r17s.

 

I live in a rural area so its all empty 2 lane backroads or highway driving when I go to work. I also drive like an old southern man that's never in a rush, so that definitely helps.

 

Bought and set up a scangauge 2 since my Autel Maxicheck pro refuses to read transmission temps.

 

Yeah thats pretty great for the mods and city driving

 

That’s strange, the autel should read it. You’re going into Engine and then live data?

 

Thanks! It was more about I had never heard of that yet so was really curious what that mod was (not so much your wording ). Is all that done with some sort of external programmer or is it a matter of adjusting things within the light controls/etc?

 

Until my eyes crossed. I might be missing something, but damned if I know what. Whatever, the scangauge seems to work.

 

Installed Go Rhino RB30 bed liner coated running boards today on my new to me 2019 Limited. Very impressed with the high quality of these boards. The install was straight forward and easy. I like that these bed liner coated running boards are not slippery and they poke out far enough to prevent door dings. Real Truck is proud of them at $800 for the set.



A little side by side comparison of my Tundra Go Rhino boards and my F350 Tremor Super Duty boards. Pretty similar in design.

 

No. If you upgrade from non LED years of the Tundra to LED, the easiest way to do it properly is using iHackers's custom harnesses. There are options. The best one involves a little more work.

If you want to double check it will be near the bottom of the list, I can check on mine to see what’s around it

 

Big fan of the Bed rug…ordered and installed it.

 

Well sorry guys didn't me to put out fake news about the crush washers on the differentials.. got a case of CRS

 

Pops rig update: she’s close to completion hopefully done here in the coming weeks.

Rear bumper back from powder and mounted. Wiring almost complete. Custom airbox in the works this will feed from the cowl. Rear harness bar and platform in the works.

 

For any who are interested:

 

Love their constant sales. And they have historically been responsive.

For the first time and after many, many orders from them, I ran into a complete pause in shipping. Not sure what happened, but also, the email confirmation for shipping appeared to be different somehow (as in, the shipped from account was different). Regardless, I had left them a voicemail about the two orders and then I received shipping for both by 0900 the next AM. So, good response, just something different about my mid-Jan and mid-Feb orders. Hopefully I'm the only one with the issue and it isn't a sign.
