Manual Hub Conversion for the 1st Gen Tacoma & 3rd Gen 4Runner

I do have a manuel diff tube.

 

Pm’d

 

He's good people; even brought the diff down and dropped it off to another member for me to pick up (which I'll do...one day)

 

dont use the add, the whole point of manual hubs is to eliminate all failure in the 4x4 system which would be the add actuator

 

As someone who has read a lot on these forums (than I care to admit), the ADD system isn't a weak link at all in the 4x4 system. That includes talking to many people here on the forum that wheel on 35s.

Manual hubs are prone to failure as well; I read about one case being so bad that the hub couldn't be removed on trail. Will have to remember who it was but they posted pics in another thread.

 

its not the actuator itself its the vacuum lines or the wires if you have the electronic actuator

 

Thanks for sharing my video. Part 2 is actually the video where I swap Tacoma manual hubs into my 3rd Gen 4runner ABS knuckles.

I found this while trying to figure out the difference between ADD and manual-hub spindles and bearings. When I swapped my Tacoma to manual hubs and deleted the ADD tube, I found the sensor on the tube that turned the 4wd light on/off. Cut those wires and twisted them together, now my idiot light works again. No need to get into the computer or cluster wiring. And let’s face it, I need that idiot light.

 

So when I went LT, the kit came with manual hubs. Everything seems to be working fine without modding the ADD on my truck. I can run hubs unlocked (2WD) in hi/lo and lock the hubs giving me 4WD hi/lo.

Ive read some people having fitment of stock manual axles not fitting the ADD diff, as I'm going back to MT I would like to know if anyone has input on if they fit normally.

I personally dont want to pull the diff and all that out to put in a hose clamp, but from what I can tell, 4WD works just fine as is while the hubs are locked? Is this accurate?

 

The diff side of ADD and manual hub CVs are the same


You can leave the ADD axle tube in place and let the add actuator engage it when 4WD is selected -- it's just another potential point of failure

 

No way to cut holes in center caps to fill that little space?

 

There are OEM center caps with holes that came on Tacomas with manual hubs and alloy wheels. But I prefer mine totally nude like the olden days.

 

Planning on doing this on my 04 with add and the push button 4wd, i would rather not do the hose clamp thing but if i engage 4wd while cruising and my hubs not engaged wont i blow up some gears or something? Being that the diff isnt spinning then all of a sudden its going 40mph, not that i would intentionally engage at that speed with hubs unlocked but what if i bump it with my knee or something

 

@stihlslayin, your ADD actuator just wouldn't engage. With a push button T-case you don't want to lock the actuator into 4WD with a hose clamp. Allow me to quote myself from page 1:

"Leave the ADD actuator in working condition because that's what the 4WD button operates. It's the only way to shift in and out of 2-HI and 4-HI while driving. You can't have purely mechanical 4WD like us cool J-shifters, but you can still unlock your hubs for normal daily driving and greatly reduce drivetrain vibrations and CV axle wear."

 

@DJB1, Sorry to ask about this old thread, I’m on the conversion process for my 2001 Tacoma with ADD Diff but I didn’t get any luck trying to get a whole spindle/hub manual non add assembly and the two peoples that I found it, they are asking too much money for it, so my question is: Can I use my old spindles for my add and buy new bearings, seals, CV Axles and hub for (non ADD) manual version?
Thank you and sorry to bother you.

 

If I’m reading this correctly…absolutely. I just swapped all manual internals to my spindles not too long ago.

 

@WorldwideTacoma thank you to confirm. Let me ask you something, the wheel bearings for ADD and manual hubs are different? If so, do you remember the bearing part number from Toyota?
Thank you

 

Manual CV's have been a royal pain to find reman'd lately. Toyota was backordered til March

 

Its the same bearing. Part number is 9036954002

 

@WorldwideTacoma thanks man. So I only need to buy the manual hub, cv drive axle non add and free wheel hub to completed the conversion?
