Toyota Tacoma 2022/2023 Rear Axle Nut Recall Procedure

- More information about the Tacoma rear axle nut recall, the recall procedure at the dealer is as follows:
1. Remove each nut, do this one at a time so the axle does not move and damage the o-ring seal.
2. Once you have a nut removed check the surface of the nut and make sure it is flat, check the area on the axle end plate where the nut seats and make sure there is no weld splatter on the surface under the nut.
3. If you find weld splatter on the surface under the nut then take a file and file down the weld splatter so that it is a flat surface. If the nut has damage from the weld splatter then replace the nut.
4. I added this, when you replace the nut put a little bit of blue loctite on the stud threads and spin the nut back on. Torque the nut to 41 ft lbs. Repeat this with all eight of the nuts, four on each side. The blue loctite will keep the nuts from backing off from road vibration.
I saw a video of a Toyota mechanic doing this procedure but he failed to use any loctite. These nuts are not a locking style nut so I am puzzled as to why that Toyota mechanic did not use any loctite, it looks like Toyota used some kind of thread lock when the axle was assembled because the stud threads had a white substance on them like a thread lock of some kind.
Now here is where I don't think Toyota has been exactly honest, I down loaded a copy of a page from a Toyota Tacoma manual and that page shows the torque spec is 27 ft lbs of torque. But a Toyota mechanic says their shop manual is showing 33 ft lbs of torque. Now here is the real kicker and where I think the true problem is and that is the Toyota recall procedure for the dealers calls for torquing the nuts to 41 ft lbs of torque.
That is three different torque specs, I think what happened is Toyota called for to low of a torque spec and that contributed to the issue, the recall procedure is calling for almost 34% more torque on each nut than the page I downloaded from a Toyota manual and is 19% higher than the torque spec in the Toyota dealers shop manual the Toyota Mechanic stated. - ยานยนต์และพาหนะ

Good info. Doesn't seem like a bid deal.
I wrote out the procedure above as well so you have it step by step. This will take you about 30 minutes total to remove each nut and check the surfaces, put some blue loctite on the studs and replace the nut torquing it to the recall spec of 41 ft lbs of torque. I hope this helps those who don't have time to go to a dealer and leave your truck for a day over a 30 minute to 1 hour job if they have to file down the weld splatter if yours has any. This took me a total of 30 minutes to check all eight of the nuts and mine was fine. My trucks build date was 5/23 so that might help others knowing the build date and the outcome of my truck on this recall. I will not be taking my Tacoma to Toyota for this.
Best explanation to date! More plausible that a combination of slag and under torquing the nuts. I agree with you on using med thread locker. After torquing the nut you can always mark the nut with a sharpie and see if any of the nuts loosen
Also have to check the stud for welding splatter and the stud would be replaced if the stud has splatter. If there is splatter under the nut. It gets filed and the nut is replaced with a new nut. A second visit is required for the stud replacement. They mark it with a paint pen and order parts. Its a big job if studs have to get replaced. Its a quick in and out if its just the inspection, slag removal and nut replaced.
I have a 2022 Tacoma SR5 V6 with 10000 miles, but I have not had any symptoms as described in the letter. I'll make an appointment ASAP. Great information and video. Thanks 🛻🛻
Good video
I just did mine today and all 8 were fine. However, I did fine a spatter of weld slag near one bolt on the driver side…the bottom bolt closest to the front of the truck, but it did not affect the seating of the bolt. It took me about 30min. I used 41ft/lb and blue lock tite per your recommendation…thank you!
Glad you had no issues, now you don't have to worry about it any further.
Thank you so much for this video. Great job!
I totally agree did mine as well and they were probably somewhere around 25 ft lbs, I’m a plumber and used to torquing anchors so I have a good feel for torque, they were way under torqued from the manufacturer
Mine were not very tight either when I removed each nut. None of the nuts had any weld splatter under them. I did reinstall each nut with blue loctite and torqued each one to the recall spec of 41 ft lbs of torque. My 2023 Tacoma build date was 5/23. The recall covers all Tacoma's with a build date starting from 5/22 through the end of the 2023 model year production run. Toyota nor the axle supplier knows how many Tacoma's were actually affected.
Thread locker changes the fastener stop looking torque as it creates a “wet torque”. The confusion about 27 and 33 is that the manual states both newton meters and lbs ft torque values.
36 Nm equals 27 ft lbs of torque, this is not a confusion of Nm vs ft lbs of torque. Toyota has now printed three different torque specs for the rear axle nuts, the first being 27 ft lbs, the second being 33 ft lbs and the last in the recall notice of 41 ft lbs.
This is from the Permatex Technical Data Sheet: Assemble and tighten as usual. When tightening to established torque values, .
This is also from the Technical Data Sheet: PERMATEX Medium Strength Threadlocker BLUE is a medium strength anaerobic threadlocking material, which cures between engaged threads to form a unitized assembly that resists virtually all leakage, shock and vibration. The product is a single component, anaerobic liquid that cures when confined in the absence of air between close fitting metal surfaces. Ideal for all 1/4 inch to 3/4 inch diameter nut and bolt assemblies.

You're on top of your game. Good job!
They said mine was good to go. I inspected them myself and never saw any signs of spatter and nothing was loose.
Just stumbled upon your channel. I see your handle relates to a Ford product. You should be driving a Ranger, you wouldn't be having these issues, lol. I love my '21 Ranger!...Just kidding, thanks for the information on the Tacomas and good luck to you
What are the torque specs for pre 2022-23 models?
According to a Toyota mechanic their shop manual says 33 ft lbs of torque, but again the recall procedure from Toyota is calling for 41 ft lbs of torque. The rear axles are the same on the pre third gen 2022/2023 models so that is why I think Toyota was under torquing these nuts.
If you have a pre 2022/2023 model I would not worry about them.
So, if a guy were looking at a 2023 Tacoma the recall shouldn’t necessarily dissuade him from purchasing it?
No, this recall is minor in nature, all you do if weld splatter is found under the nut you file down the weld splatter and replace the nut if at a Toyota dealer, Even if you see a small scratch or indentation on the bottom of the nut that is not going to cause a problem If the entire under side of the nut is grooved then replace the nut if you are doing this yourself. I would however use blue lock tight and use the recall notices 41 ft lbs of torque.
this is as simple as a recall as it gets. The tundra has recalls with machining metal shavings inside the engine destroying the engine, that's the kind of recall that should siuade you from buying.
For a new trucks it has a lot of problems
I know that torque wrench cost 🤑🤑🤑
ANNOUNCEMENT: Many Loctite formulas require the use of Loctite's primer. If the primer isn't used, the Loctite wont work.
Loctite hardens by stealing elements from the metal, so if the metal has any coating, the primer needs used.
Generally, the formulas that need a primer end with a positive number. It's best to double check your formula.

The studs and nuts used for the axle bolts will fall under the active metals and will not require primer. While you can use primer on the active metals it is not needed and you will have to work fast or the thread lock will harden before you finish installing and torquing the nuts.
Hahaha you don’t need lock tight.
Does not hurt to use loctite, these nuts are not a locknut style nut and they do not use a lock washer so to be safe loctite is a good idea.
@@mustangecoboosthpp3869 if you were my mechanic, I would be very appreciative of you using blue loctite, thank you
