Ever wonder just what the hell's going on in there?
Well wonder no more.
You're Welcome.
Still helping people 6 years later, thanks.
I just got a 97 t100 and was really curious about the vacuum operated 4wd. Your video was the first one I clicked on and I’ll say how informational it was. You made it extremely simple to understand thank you.
So simple but no one ever mentioned just dropping the drive shaft to make that CV assembly looser to get out. 👍
Great video! My '90 4Runner was recently not engaging in 4WD after I had installed the manual locking hubs. Turns out I had the vacuum lines criss crossed by accident! Once I switched the lines, the 4WD worked perfect as it should! This video helped me see and understand how the vacuum line system engages the 4WD on an auto locking hub vehicle. Thanks for sharing!
Ummmmm....... The vacuum li es are to engage the AUTO locking. Why would you need them if you do manuals? (Huge mistake IMO. Auto lockers for LIFE!!!)
@@Syrus54 Because I don't want the constant wear and tear of my CV Axles spinning non-stop when I don't need 4WD.
my vacum accuator was busted so i made it manual with a rod going tru the floor in the passenger under the dash location,. a small plate with a couple of pivot points at the accuator location and a lever ( conected to the rod inside the cab) ,.. so when i twist the rod it pushs or pull on the shaft whitch the vacum diafram is hooked on too.
SUPER educational. Thanks so much for posting this!
Great video. Saved my ass with this one. Thank you
Thank you
Aloha it helps to always watch a great video mechanic mahalo for you tips🤙🏽🤠
This was awesome to see, thanks man
do the A.D.D. modification. did it on my 4runner,i now have locking hubs and NO electronics or vaccum to engage 4x4. its bullet proofed
Could you post a link?
Hey mate I have a 1992 Hilux it had the gear box with automatic locking hubs transfer case but I put in a 2004 g52 an now no 4wd. was wondering What is the best way to go about getting 4wd back?
can i use manual locking hub on ADD ?coz the right side its damaged
Hey man... i have a problem my 93 4runner back wheels kick when I turn on my 4x4. Can you help
I'm about to watch the video. I plan on swapping one tons soon. So I didn't want to spend money on locking hubs. But I recently installed Chevy engine and driveline. I thought about wiring up the vacuum system from switch inside cab for now to activate front diff. Right now all vacuum stuff is removed. But I still have the servos... Does anyone have a good diagram showing how it works so I can hotwire it. Theres only two tubes that come from the actual diff but there was also a canister under the wheel well etc...
you must have figured out front is 7.5" rear is 8" so you can not put rear gears in front? not seen any replies to this to tell that:)other then that, good video
So long ago I dont remember.
Very good video, I own a 1991 Toyota pickup V6 4x4. Stumbled upon your videos when searching about 3vze turbo stuff. Pretty cool that you actually did it, even if it didn't last. I do all sorts of work on mine, 315,00 miles and counting! Love those trucks and I was just wondering about the front axle vacuum stuff. Keep the content coming! Any plans for the engine in that truck?
You mean, Any plans for the 3VZE? not really. It's been a great engine, and I'm gonna run it until it finally quits.
Then I'll probably do a Rebuild video, and run it for another 1/2 million miles.
But if you mean Horsepower-wise... No. Nothing for atleast the next few years.
Actually a fifth gen HiLux if you're counting.
thank you 💖
mine is stuck on 4x4 so I have to replace that vacuum box?
This is so good! Thank you very much!
my 4x4 '94 22RE 5-speed pickup bucks when I put it in 4wd. makes me wonder if one of the previous owners swapped the gear ratio on the front or the rear and left them mismatched. according to the vin sticker axle code, it says it's supposed to be a 4.10 ratio. guess it's time to count some wheel & driveshaft rotations then throw down some simple division.
cbh148 mine bucks like that and a gear was broke.
it was educational thanks
Good day, can you make a video of the new automatic and mechanical lockers of the Land Cruiser and Nissan Safari uses? They gave after time a noise but I can't find out what the noise can be. Thanks for the video.
Sure... Send me the truck.
So I've got the same set up but I've changed the gearbox witch is full mechanical transfer case so it has no vacuum. I wondering how to go about getting 4wd cos the front axle isn't engaging
Hubs? Turn them to engage (or so ive heard). You shouldda went auto like mine.
If you had to remove the driveline to turn the axle 4wd is engaged is it not? Liking your video so far I too couldn't find any info on this system.
I believe so otherwise he would have been able to just turn the axle freely
cool video
Hi there can you please display where there vacuum pipes lead to the top
Should goto the vacuum solenoid things on the fender, near the fuse box
Nice video very usefull
I own a 94 v6 4x4 sir, , wondering about my front axle when engaged the 4x4 the front differential locks the 2 front wheels or only one, since the back one has limited slip IDK how the front one is, does it become positive traction on front one?
HELP
!!!! I just got a 98 4Runner with only
140K. Can someone point me in the right direction in
resolving my 98 4Runner issue? When I engage 4H it goes in silent but when it
goes back to 2H (disengage) there is a loud bang (like a sled hammer bang). After
depressing the 4WD (4H to 2H) there is a delay for about 30 second before it disengages
as I drive down the road below 25mph. The 4wd light indicator goes on when I
press the button and it goes off with a bang returning to 2H, the light never
blinks. Can anyone help me troubleshoot what to look at to solve the hard
disengagement with my 4WD? Any suggestion would be greatly appreciated.
Vacuum leak?
Where do the vacuum lines run to please?
Theres (3 i believe) colored vacuum sensors/solenoids on the fender? Thats where they go. Look online for schematics
I did a manual swap and I don’t know how to activate it
What number of differential do you use for a 3.0 motor in the solid axle swap?
Are the vacuum lines metal or rubber?
Rubber
Was your front gearing 4.3?
Uh.. i cant remember. I think so. Pretty sure it was 4.1 or 4.11... Something like that.
