We Broke The 4Runner 4WD | Do This Before It's Too Late!

- Опубликовано: 7 апр 2023
- Welp, we broke the 4wd on our brand new 4Runner. According to Toyota, water got into our front diff actuator and ruined the internals causing the front diff to not engage. So we had to pay $1500 out of pocket because it was not covered under warranty. I would suggest extending your front diff breathers before this happens to you! We thought the factory location was good but apparently not!

We had the same thing happend to our 2014 4r. Water definitely seeped in through the seal for us also. ( Guess that's what happens when I high center the dang vehicle twice lol)
$1400 is crazy. Its honely a super easy fix and the part is couple hundred bucks. Toyota used to have these things inside the transfer case. Thankfully they are now starting to make the replacement of the actuator more service friendly by allowing access to it from the outside of the Tcase.
If there is a next time, y'all should install it yourselves and make a video out it :). Y'all shoot great content, loving the channel!
Oh I’m certain I can easily install this. We just took it to the dealership because it was under warranty and thought it would be covered. But no.
Also thanks for the feedback on the channel! Glad you’re enjoying the content.
Can you check on the receipt from the auto parts store, some sku or description numbers for the parts (couplings) and hose sizes , I have the same year and will love to do the same job. Your videos are amazing!!!
715-1812 is the part number for the one pack of fittings I got from NAPA. This pack had the small fitting I used. The bigger hose OD is 7/16, ID is 1/4. Small hose OD is 5/16, ID is 5/32.
With this in mind, what about the breathers for the transmission and transfer case that are up between the engine and firewall? Perhaps the breathers you relocated are more susceptible to water intrusion because they are near the fender.
Faulty parts or using parts from long term storage during manufacture? Due to supply issues is my guess.
Had a wheel bearing and abs speed sensor fail on my 22 within 6 months of purchase.
Dealer said bearing was scored and abs sensor wire corroded.
Corroded? The vehicle had only been manufactured 9 months earlier.
Faulty parts fine it happens but corroded parts in a new vehicle makes me wonder how old the parts were.Due to supply issues were they using old parts to keep production on schedule?
Had the same issue, Toyota said the same thing in Arizona (Not alot of water here). 21 4Runner Off Road Premium. Thankfully Toyota covered most of the expense but it did cost me about $400. I am thinking of doing the same thing with the breater so I am curious if this works. Dealer metioned greecing inside around the seals during the replacement. Thanks for the video, you are always informative.
Thanks for the feedback! It wouldn’t hurt to extend the breathers if they are the culprit. Couple bucks at the auto parts store and 10 minutes of work.
What if you spray WD-40 water displacement number 40 on the whole unit on a regular basis?
It is true they have to spilt the transfer case to replace it?
Im getting the arb breather added right now. Im not doing the front just like you. This has me worried though
I would look into getting it done. Better safe than sorry.
I’m on my 3rd Actuator on a 2018 with 115000km on it. All within 2 years. Toyota replaced 2. But I paid out of pocket for the third. They were baffled by this as they’d never heard of 2 going on the same Toyota. Told me it was because of my life which is a standard 4Runner lift. I called BS on them. But they told me that’s all they could say was the reason, take it or leave it. Thanks for the vid.
That’s my only fault with the newer Toyotas , all of the lazy man electronics and bells and whistles. Bring back the simple no fail manual locking hubs and manual 4 wheel drive shift levers not only with Toyota’s but with most manufacturers. Everything is made to be so easy now and we end up paying big time for that.
I’ve had my front seal leak at 45k and the dealer replaced it via my extended warranty. Already have the ARB breather kit planned to install so it looks like I’ll be doing the front one too just Incase
That sounds like a good idea. Our truck has 2k miles and this happened.
So new in the 4Runner seem what is the ARB breather to
If diff breather for pressure to escape, I wonder if it would be possible to make a device like they have on those bottles of ketchup that are made to sit with the bottom being where it squirts out . They have a slit that will allow the ketchup squirt out when you apply pressure on it, but it wont let liquid back in unless it is under pressure. The pressure from the differential or actuator would "burp" out for lack of a better word, but would not let water to come in.
Lol, good idea. I don't know if that would work or not.
What if you seal the outside?
I thought the only 4Runners that had actuators were the models that have the round dial to engage 4 hi and 4 lo.
And the models with the actual shifter stick in the vehicle used some type of cable or linkage system to engage it.
Can you shed some light on that? I have a 23 Off Road premium and just curious if I have that same actuator in the front. Thanks.
I'm not too sure which models do and don't have the actuators. You should be able to look behind the skid plate and see if it's there or not.
All the 4runners have an acutator on the front differential, that's how the clam shell differential switches from 2wd to 4wd. The shift lever in your trd orp is a shift lever for the transfer case not the diff. The sr5s have the knob shifter instead of a lever to engage 4wd to the transfer case. The sr5 also has an acutator on the transfer case, where yours does not and is manually engaged hense the lever, also sr5s acutators on the transfer cases tend to fail over time due to moister getting in and burning out the internals of the acutator or they tend to seize up in the rust belt states and won't engage 4wd. These are some are some the 4runners weakness parts. A simple fix I've seen was to silicone around the black plastic acutator box on the diff, not sure if it's a 100% of a fix but it's 50% more prevention of failure
@@jdown86 good info. Thanks.
@@yotaxpeditionI have a 2023 SR5 Premium 4x4 and it has the exact same actuator on the exact same spot.
Have a 23 ORP coming in a few weeks. Question, did you pressure wash the undercarriage after 4wheeling? I’m wondering if you hit the actuator with really high pressure if that might have caused the issue?
We wash the 4Runner after every trip. But the diff is covered with skid plates so I can't see that happening.
That what I suspected mine was but the dealer found debris that would not come from the car wash.
@@ArizonaOutdoorAdventures Seems odd, I wonder if one needs to re torque or check these fasteners, or if they changed the gasket or seal. Toyota rarely changes anything it doesn’t have to late in a model life (why I’m buying one now), and this platform is well known for reliability and off-roading durability
@@barryscott990 Mine was brand new
So if this hasn’t happened yet should we be resealing that cover with some ultra grey or a like silicone?
Extend the breathers. You could also make sure everything is tight on the actuator. If you take the actuator off you're going to have to drain the front diff fluid.
I'm curious why you didn't just extend the lines over to your ARB breather?
You could. Just need to get different fittings. The original lines are rubber whereas the lines going into the arb breather are plastic. Would need a fitting that threads into the ARB breather and has a barbed end for the rubber hose to go on to.
I wonder if the models with the shifter lever instead of the knob also have this issue. Might perhaps be a good argument to go with the lever over the knob
Our 4Runner has the manual 4wd shifter. Either way, both probably have the same actuator.
@@yotaxpeditionI have 2023 SR5 Premium and it has the exact same actuator at the exact same spot.
What does the breather do? Do you offer installations and where are you guys located ?
Thank you
So you have 2 breathers up there. One for the front diff itself and one for the actuator. The breather on the front differential is necessary to allow the pressure it builds inside to escape. I’m honestly not sure why the actuator has a breather considering it’s electronic. But yes we do installs if parts are bought through us. And we are located in Alburtis Pa.
@@yotaxpedition If it is for pressure to escape, I wonder if it would be possible to make a device like they have on those bottles of ketchup that are made to sit with the bottom being where it squirts out .

The pressure from the differential or actuator would "burp" out for lack of a better word, but would not let water to come in. I am also going to post this as a new post as I am curious if it would work and see what others opinions are.
Hi bro, what's your wheel brand and size? Thanks
They are Fifteen52 range hd. Size is 17x8.5 et0. We have a full video on them! Check it out!
What size are the lines and couplings you bought?
What I did was take both breathers off and took them with me to the autoparts store to get the right size.
I have a 22 4runner sr5 with the electric transfer case and when I activate H4 the dash light blinks and when I do tight turns the front wheels seem to “hop” does that mean 4wd is engaged even if the dash light blinks? also how do you disengage H4? when i turn the dial to H2 then dash light is still on. Do you think I have the same problem?
Sounds to me like your 4wd is working. Something does sound weird though with the light flashing even when going back to H2
Hop? Are you driving on dry pavement in 4H?
Never seen this before.
That’s actually scary thinking this might happen on a trail.
The unit should be 100% watertight. And it's hard to imagine water getting in through the breather. And it if did, it wouldn't be much. Probably a better chance of getting water in it while washing your engine bay.
What was the second breather that was by the actuator breather? Do you know?
One is for the actuator and the other is for the front diff.
@@yotaxpedition thought that might be the case. Thank you for clarifying.
sheeeshhh! $1,400. Of course dealerships will charge you an arm. It’s scary cause I have a 2021 Trd and that looks like plastic compared to my 1996, all metal 😢
FYI - the front diff actuator needs to be engaged about every month or more and driven for about a mile each time. Otherwise, the oil sits at the bottom of the case and doesn't get splashed around causing the internals to freeze over time. Considering the front diff breather line ends toward the top of the engine compartment for newer models (2014 and up, I believe), I think the claim of water intrusion is BS. It's more likely that the front diff wasn't engaged on a regular basis. Regardless, this sucks. Also, make sure to use a thick, silicone-based grease on the Park-Neutral-Safety Switch where the wires attach. If those corrode over time, you won't be able to either get the transmission out of Park and into Drive, or out of Drive. Why such a crucial switch is left exposed is beyond me.
This is a very good point! Ours is engaged often as we are testing products and off-roading frequently, so that is not the issue here. However we do not think it got in the breather either. We suspect the water got in through the seals on the actuator. We had the truck submerged in water for an extended period of time where the actuator was most certainly under water.
Both the internals of the front diff and transfer case spin while the vehicle is in 2wd, splashing oil. Oil is not just sitting.
I would not be surprised if this will be the next class action lawsuit like the rav4 with their leaking roofs.
We'll see. Its gotta happen to a lot of people before anything like that happens.
All the times washing the engine bay never heard of covering these breathers? ARB yes, but not these. Then the stock rear diff breather would be really susceptible to water coming in? Doesn’t make sense what the dealership said.
Even spraying water onto the breather, it would be hard to get inside. It's designed in a way where it's almost impossible unless it's submerged in water. The rear diff breather is always the first one to be extended because it is so low. Not sure why Toyota didn't extend that from the factory.
Does this only apply to the Limited model 4runners?
If you have a 5th gen with 4wd then they should all be the same.
Trd off road , venture and pro are different. Limited, sport and sr5 are electronic 4x4 shift.
@@jimher357 that’s what I thought my TRD ORP has a manual 4WD lever
Right, some have shifters and some have knobs. But they might all have the actuator on the front diff.
@@heykat18 the 4wd shifter or knob selector engages 4wd in the transfer-case. This part in the video however refers to the front differential. All 4runners with part time 4wd has it. Not sure if the limited has it.
Question....did they give you your old part back? Sounds like you got scammed by toyota.
No but I wish I was able to inspect they faulty part.
The law in TN is they have to give you your old part back, bsure2 to mark your part in a way you know it is your so they are not just giving you back someone elses part. @@yotaxpedition
Plea the 5th..
That’s unbelievable that it wasn’t covered under warranty. What’s the point of getting the warranty if something as small as that isn’t going to covered
Yeah, I was surprised when I found out it wasn't covered. Im not sure why it wasn't covered. I wasn't there at the dealership when it got fixed.
It has a AFTERMARKET diff breather on it. That’s all Toyota needs to see to put the blame on the aftermarket part. Over and done with but a better option would be to remove the breather kit before you take it in for the diagnostic. While that can be a PIA, paying $1400 hurts more IMO.
@@goforbroke2 “Aftermarket” has only a minimal impact on warranty. It still has to be proven that the aftermarket item caused the damage, plenty of warranty claims go through on vehicles with aftermarket parts.
Toyota build quality vehicles, but they do break down and out of all the manufacturers. I’ve noticed they are very strict with their warranty repairs. People continually rave about Toyota until they have a problem…And when something goes wrong, it’s usually very expensive!
definetly sus... sorry to hear this happened 😢
Yeah, we feel like this shouldn't have happened.
11.7mpg!! How much weight are y'all running? Judging from other folks comments, it seems the warranty is hit or miss on this one.
Yeah, our mpg isn't too good. Not a lot of highway driving so that's why our average is so low.
Sounds like you got bamboozled by the dealership lol
Possible. Just letting people know this could happen.
Man toyotas greedy, $391 - acuator, 1 to 2 hour job max - $1000 lol, ive seen people silicone around the black diff acuator box it's helps prevent moister getting inside.
I personally didn't take it to Toyota. If I knew it wasn't covered I would've done it myself.
Sure seems like Toyota quality and customer service has gone down over the years…..they’ve sat on their laurels for far too long….we need new competitors to show up and take their candy!
Yeah..Toyota warranties are GARBAGE..you pay out the arss....40k-80k... and you as the consumer have to pay for their ENGINEERING FAILURE
This is why you don't mod new vehicles. You wait for issues to popup so you don't pay out of your pocket.
I call bullshit did you look at the warranty to see if it was covered. Toyota should’ve fixed it under warranty! I would be raising hell until they fix it for free.
I personally didn't take the 4Runner to the dealership so I don't know the details. I just know we were told it wasn't covered and we had to pay for it.
Toyota is notorious for denying claims. If you complain enough they will usually cover the issue. If the dealership still doesn't want to cover it, speak to a Regional Manager. I had a 7 month old car with the clear coat coming off. They said it was due to acid rain. But, the clear coat was separating from the paint. The outside of the paint wasn't damaged. Keep after them and good luck.
Toyota fan boys, reliability unmatched...me in my Nissan Frontier 🤣🤣
I mean. I don't hate the new Frontier
Try and re-sell your Nissan in 7 yrs..ROFLMMFAO
Was a supplier to Toyota and Nissan. Sent about $90 million in parts yearly to the manufacturing assembly plants. Toyota was by far more quality focused than Nissan.
I would recommend trying a different dealership next time, that really sounds like a warranty claim. We have a sr5 base with the 4x4 knob and a sr5 premium with manual 4x4 and they both have diff breathers and both been up to the headlights in water and no malfunctions so idk maybe just a fluke.
The dealership we go to is the best in our area when it comes to the offroad market. It's the dealership we bought it from and they also do builds on Tacomas and 4Runners
I’m not understanding why it was not under warranty?
I don't know either.
