[@dave8428]

I have an 04 Toyota 4runner my H2 and H4 work perfectly but my L4 blinks when it’s in Neutral and it doesn’t stop and of course when I put it in drive or reverse it gives me that beeping noise. Have any idea on how to fix that?

[@dave8428]

I always have trouble finding info on the year of this 4Runner and trouble figuring out the parts and names. I just bought it, had it for like almost a year now so all pretty new to this stuff and fixing it but I love it so far.

[@user-ql9sz1oq6r]

It's been 10 years since I tested 4lo and locking diff and both worked like a charm thankfully. I will make sure to do this once a month from now on. Thanks for the heads up

[@Jager-er4vc]

[@RicktheRular]

This comment influenced my decision to buy a 243k mile V8 4x4 Limited and I actually got it cheap considering I can sell it and make a 3.5k profit instantly.

Also one of the few 4th gen V8 owners out there, I definitely appreciate your videos man. Keep them coming, you've been giving me great ideas!

[@CanadianGearhead]

Thanks for watching 👍

[@johnd830]

Thanks for your video. If your actuator for 4Lo doesn’t engage you should not panic. It is indeed stuck but there’s a decent chance it can be freed without a T-Case rebuild. I did this on my new-to-me 2008 V8 by repeatedly engaging and disengaging the transfer case several dozen times in my driveway, in between some of these cycling attempts I was also crawling under the truck and lightly tapping the transfer case and actuator (very lightly) with a dead blow mallet. After about 20 minutes or so it finally popped into 4Lo. Some people on the forums suggest doing this process with the vehicle warmed up, others have found success with partially loosening (but not removing) the bolts for the actuator. However I would try the former method for a while before resorting to this. PS - can we talk about how backwards it is that the GX got a manual lever and the T4R got the electronic. That’s some marketer’s logic right there, let’s make the Toyota seem fancy and the Lexus seem rugged.

[@smokestack9795]

Also, change the transfer case fluid as well as your differential fluids as recommended by manual. I know from personal experience, even though I exercised it monthly, the fluid changes made it for smoother engagement of transfer case.

[@arrowdog8852]

Appreciate your video, but these do indeed have a 'center' differential... it's call a Torsen differential, and it's what enables _full-time_ 4WD on pavement. Don't confuse it with the nomenclature of a traditional transfer-case on part-time 4x4's. e.g. Jeep Wrangler. Different animals. BTW, I also dislike de-throttling (drive by wire) with VSC.

[@conorkenrick3779]

I bought my 4th Gen Limited V6 last year with 100k miles. While 4H would engage, I couldn't get 4LO to engage for the life of me. I had mostly written it off until last week when I took it to do some very light off roading and attempted the 4LO. In a matter of seconds, it engaged! Now that I know it works, it's going in to have the fluid replaced and I'll continue to engage it every month. Great video!

[@danschubert595]

I have a 2005 4 Runner and I just cycled my 4WD High and Low switch while detailing my car in August. I enjoyed your video. I have never been stuck with my 4 Runner here in WI even while out on the lakes ice fishing. 140,000 miles and no rust on the 4 Runner!

[@davidlandreth-smith9485]

Nice video and good advice, thanks for sharing. Hope you don't mind just one technical clarification though.....your 4runner does in fact have a center differential as well as a transfer-case. Yes all 4x4 vehicles have a transfer case but all wheel drive vehicles have three differentials, one each in the front and rear axles and one on the T-case to take up difference in rotation between front wheels and rear wheels or else you get transmission wind up and excessive drivetrain and tire wear ( on the highway/road). The center differential lock is needed for true real world tough four-wheeling, or else you can get all the power spinning say the rear wheels ( if they be in mud say) and no power going to your front wheels. So the center diff lock switches you from all wheel drive to true four wheel drive for off-road. Hope this helped and didn't piss-off everybody. 😊

[@CanadianGearhead]

No worries, you're right. The confusion is that it has its own button, where most other vehicles have all the settings (4auto, 4hi, 4lo) all on one switch for the transfer case.

[@acemoto2319]

May i ask what settings are best for 1)dirt roads 2)snow ❄️ 3)steep rocky Hill up 4)steep rocky Hill down 4)deep rain 🌧️ water city 🏙️ street 5)highway 40-70mph Thanks 🙏

[@moose354]

Actually, the point of failure is the seizing of the Automatic Differential Disconnect (ADD) which is located in the front diff which is a solenoid actuated sleeve. The ADD on my 2004 Tundra did seize because I failed to routinely cycle the 4WD. I was able to tap on the ADD with a hammer and free it up. I learned my lesson and routinely cycle the 4WD monthly.

[@blaked5974]

Great video. Thanks for reminder. Very commonly overlooked. Never had this problem with my 08 4Runner Limited 4WD v6. However I do have it with my wife’s Land Cruiser. Last month I drove her LC out to a sandy muddy area to activate 4lo but it ended up getting stuck in 4lo...unable to get back into 4HIGH. I’ve also had problems in the winter where her actuator light will flash when cold cranking vehicle to start the day. I really need to use the 4lo and locking diff more often. These issues are usually resolved once LC is warmed up or I turn the vehicle off and back on again. Going for 300k+ miles in both vehicles(already did it w two other Toyota’s, a 91 4Runner and 97 Land Cruiser). Best built vehicles on the planet!

[@wickedcrypto6004]

I knew I was't going crazy. This happen to me in 2004 when I bought my 4th gen. I remember stopping at a stop sign at an intersection and the moment I decided to go my wheels slip and my 4 runner just stiff the fuck up in the middle of an road where it could of cause an accident instead of avoiding it. I remember thinking why did I trade in my explorer for this junk. I eventually ended up disabling that abs crap and was finally able to enjoy my 4 runner. 2020 and I have no regrets, I still have my baby and I'm in control.

[@california199_7]

How do you disable the abs?

[@J.NOBODY.1]

Just bought a 2021 tundra few months back. I'm always making sure I put it in 4wd on the back roads at least once or twice a month. Just gotta take care of your vehicles and they will take care of you.

[@dalephillips8250]

Oh no I haven't done that with mine I will have to start.

[@shannoncrawford7212]

Good advice, I engage mine every couple of months. I never seem to have a problem with my AWD and electronic nannies. But we don’t get a lot of snow here. When it does I’ll usually lock the transfer case if snow is still on the roads and leave it in AWD for mostly plowed roads that are still spotty. I never seem to loose traction or have power cut dramatically with AWD though, 03 4.7L. If it is raining and the roads are wet I can put it to the floor and it takes off like normal. Accelerates hard with no wheel slip and no cutting out. Any rwd or fwd drive car I’ve owned the wheels would be spinning like crazy if I did that or traction control going nuts.

[@MWWOOD]

Hell yeah! Mine wasn’t working when I purchased it. It came around after exercising it once a day for a couple weeks. Cheers from an 08 V8 owner in Buffalo!

[@gurnblanstein9816]

You don't have to rebuild the transfer case just because it needs an actuator. If you know what you're doing you can actually replace the actuator without having to take the transfer case apart. You disassemble the new actuator pull the shaft out slide it over the existing shaft on the transfer case and reinstall the gears in the proper orientation. Reinstalling the gears in the proper orientation is where knowing what you're doing comes in.

[@Victork32]

I put in a vsc disable switch that can be used in any mode. I use it mostly in all wheel drive (H4) for those snow days. Yes, the VSC light will come on during this. Doesn't rob the power away from you when you trying to accelerate on an on-ramp. I still get the alarm if I slide and it still controls the braking during a slide. Its the best thing I ever did. Living in Edmonton Canada, its a must. I can still use the transfer case lock as normal. In this case though, the transfer case doesn't need to be locked. When locked, its 50/50 but when its not, its 60 front/ 40 rear. I prefer when its not locked. i bought the circuit board from a Russian guy named KLIV on one of the forums back in 2008. Still working today. Just had to wire it in and buy a button for the activation of what I call "no headache mode".

[@CanadianGearhead]

[@bradley71]

I picked up an 06 4 runner V8 sport in Quebec a few years ago for 9k and drove it home to Windsor. It's needed some TLC since but it's an awesome truck (245K now). I was wondering if you ever grease your slip yolk zerk fittings. Shortly after I got home there were these horrific clunks when I came to a stop. Had to do some research to find out what was going on (thought the transmission was cooked). I grease it with every oil change and that keeps the clunks to minimum. Toyota should of definitely done a recall. They did on the Lexus GX 470. Great vids dude! Keep em comin. 👍

[@CanadianGearhead]

I shot some grease into whatever I could reach when I did my last oil change. That clunk is normal, but weird. Toyota's answer is just to keep jamming it full of grease

re camera focusing issue, in case you haven't yet figured it out: when you have a backlit scene (source of light is facing camera lens), autofocus can tend to hunt, especially when lens is dirty as seems to be the case here (it's trying to focus on the dirt which looks high contrast to it).

[@badgerstate3451]

Had sticky engagement issues with my old 3rd gen 4runner. I drained and filled the transfer case with Amsoil synthetic gear lube. Ran it for a few hundred miles and it works like new. That was several years ago and it still functions great. I'm not sure what gear oil I drained but the good stuff worked like a a charm.

[@CanadianGearhead]

That's a good point, I'm hoping that swapping the fluid will help my gf's Tacoma with 4x4 engagement

[@benjones8977]

The last snow I had in the Seattle area, I find that putting it in high four-wheel-drive and manually shifting into second or third gives me better traction when I’m sliding. Especially useful when you’re making that quick turn or a quick stop. If I just leave it in regular four wheel high, then I’m sliding.

[@FireRunner1075]

V6 4th gen you can drive year round in 4wd. Its a mutli mode 4wd system its a 40/60 split. Locking the center 50/50 split . And yes the 2009 4th gen trail had locking rear diff with the same multi mode 4wd system only avail in a V6. Very hard to find one. I had a 2006 SR5 V8 and now have 2007 Sport V6. Miss my V8. Familiar with both 4wd systems. You can do a mod that shuts off the VSC and ABS with out locking the center. Check out the forms. The 4wd Sequoia's have multi mode 4wd systems too both generations.

[@zman92630]

Couldn't agree more about the actuator. I under-used mine and although it now still works, I have to go super slow (2-3 mph) to get 4wd engaged. Sometimes, I need to back up to engage or disengage back into 2H. Kind of inconvenient, but I can't afford to get the xfer case ripped apart.

[@jasonclark5290]

[@staticclutch9932]

Man when I first got mine and started friggin around with things, I had no idea about this since I was a new owner and it was barley engaging. Eventually it started to work but after 5 years of owning it and knowing about this problem I realize how close I was to being screwed into spending lots of $$$. Perfect example of use it or lose it!

[@CanadianGearhead]

Sounds like you made it through by the skin of your teeth haha

[@Greatdome99]

3:51 No no. The transfer case has its own differential to separate front from rear axles. So you have THREE differentials. Yes, you can lock it, but that means the front wheels will rotate the same as the back. Good for off-roading, but don't turn corners on dry pavement or you're in for a $$ repair!

[@jgranger2002]

The v8 4runner is fulltime awd. The center diff lock is just that. Because the awd 4runner has a center diff not a traditional transfer case.

[@charliebrown7203]

The transfer case is always engaged. That switch is definatly a center diff lock switch. It locks the center diff.

I am pretty sure not all transfer cases have differentials built in but the 4runner does. Thats what allows it to be "unlocked" but when you lock it it functions the same as a part time 4wd without front or rear lockers

[@arjanpouwels6788]

You're right, the V8 actually has a torsen limited slip diff in the transfercase to split the power to the front are rear in awd mode. The centre diff lock button completely locks the torsen diff so there is no slip at all. It's a beautiful system, and it works well.

I mean, technically, the v8 actually has a limited slip central differential and not a transfer case, so it makes sense why they call it the center differential lock. The transfer case on the Tacoma looks and operates differently and I assume that's what the v6 4Runner has. This is, of course, just academic. Locking the center diff makes it operate just like a transfer case

[@Gringorican]

When to lock your dif: Dry tarmac: no Wet tarmac: NO! Gravel: yes Mud: yes Sand: yes Snow: yes Ice: NO! The reason hard slippery surfaces are a nope are because the wheels not being able to turn at different speeds makes it prone to spinning. Unlike in loose surfaces like snow, dirt, etc., there's nothing for the sidewall to grab for traction when the vehicle begins to rotate on slippery hard surfaces like wet or icey tarmac. So, it's prone to keep rotating much easier and put ya in a bad situation if you're not careful.

[@rangerover06sc]

A transfer case may contain a center differential, but it is not a center differential. A differential is any device that allows two shafts to spin at different speeds. A transfer case is just the box where this happens. But a part time 4wd system does not have a center differential. Full time 4wd vehicles all do. It's a locking center differential. Not a locking transfer case.

Hmmmm...my understanding of a 4X4 Transfer Case is that it either sends all of the power to the Rear Wheels in 2Hi or all of the power equally to both Front & Rear wheels in 4Hi or 4Lo. Why would a vehicle need a Transfer Case if will never see 2Lo (just sending power to the Rear Wheels)? Doesn't it make more sense that your truck (being AWD) has a Center Differential that can distribute Some of the power to the Rear Wheels & Some of the power to the Front Wheels? And when the Center Differential is Locked it acts as a 4X4 Transfer Case would. Moreso when in Low Range.

I have a 4th gen v6 that I bought used and sadly the 4 low doesn’t work assuming the previous owners never cycled it or actuated it my regular 4wd works good though no issues but deffinetely gunna cycle it more

Most entertaining video, (and educational) thank you.

I hate the 4wd systems today. Best one I ever had was a Toyota Hi Lux with straight front axle and locking hubs and a transfer case shifter on the floor.

According to the Owner's Manual for Gen 4 V6 models, the vehicle should be driven in H4 (4-wheel drive) for at least 10 miles per month to keep the gears lubricated. I have known of owners who didn't do this and lost their 4-wheel drive capability.

[@effective_biscotti1160]

Does the same apply for 4lo?

[@24hrstolive27]

So when is someone supposed to engage the diff lock? In motion? Or in neutral?

I am looking for the exact wheel well splash guard for your 4runner.

I’m so jealous of your limited V8. I settled for a sr5 V6 2007

V6 is way better than the V8 with rubber timing belts.
