Add diff to non?

So I have a 95.5 manual hub front, I am looking at swaping a 2001 front diff which has the add. So what has to happen here?

 

New spindles, cvs, and that should be all if you get the entire front diff

 

Some wiring too.

 

Haha O yeah I said screw that and just locked it permantely

 

Why do you want ADD. Most a lot of people switch to the non ADD because it reduces the miles on the cv's...

 

I assume you want to retain your manual hubs and you are only asking about the swap because your front diff failed and you have access to an ADD front diff for replacement?

I believe you just have to swap the axle tube. I think there is also a hose clamp mod that holds the engagement fork over so you to run the ADD axle tube if you wish.

 

yea I do not want the add, so I am working a deal to get a rear axel, so I want the front to match ratios. The new front is off of a 2001. It has the add set up.

So how do I go from add to manual, just pull the diff and will it fit in my manual axle tubes?

 

I just told you... Need me hubs, diff tube, and cvs

 

^False, it sounds like the OP already has manual hubs. The fact that he is getting parts off of a 2001 reinforces that the donor truck has ADD. Manual hub Tacomas were not produced after 2000.

OP: You will need to swap your diff tube. Read the link I provided and do a Google search for God's sake. There a lot of threads on other sites explaining this process.

 

yea thanks I posted a little drunk last night. I will read the link and do some more searching.
Thanks

 

Hold the phone.


If you want to still use your manual hubs you can.

an ADD diff can work like a manual diff. The only difference is the tube coming from the diff to the passenger side. ADD diffs have an actuator that slides a link over to engage the passenger side to lock the front drive shafts together. Early front diffs use vacuum to do this and new ones use an electronic actualator.



all you need to do is make sure the actuator is slid On full time. Vacuum ones are easy, just clip the vacum tube and cap it. electronic ones are a bit tricker but totally do able.



OR

you can convert to ADD hubs. in which case you'd need

-ADD CVs
-ADD hubs


no new spindles.

 

your talking about this fork.





Ok so what I am getting is I can pull the add setup, lock the fork, then throw it in?

 

That is my understanding.

If you have already taken the tube off (don't know if that is your picture) you might as well make it a clean install and throw the original manual hub diff tube on.

 

He may need the spindles too if he wants to convert to ADD AND maintain ABS (I am assuming he has ABS, don't know for sure).

 

I have been thinking about swapping my Manual hubs to electric ADD hubs. Call me lazy, but not having to get out and turn hubs would be great. Plus the ability to shift on the fly. (yes, you can do that with manual hubs, but they need to be locked in already..) I only put 5,000 miles on my truck a year, so worn out CV boot doesnt scare me..I have read a few threads where people went from ADD to Manual, and every one changed spindles. I was under the impression that the ADD "hub" was part of the spindle? Maybe you can press the hub out of the spindle, but from what I hear that is a giant PITA

 

This is true and it will require new bearings at that time. The pressing process will destroy the old bearings.

 

No it not my pic,

I have not gotten that far yet, I am still gathering parts.

I want to get everyting straight before i do this.

I want to keep the manual hubs,

So just to clarify I can swap the ADD front diff, keep the add axel tubes and throw in my manual axels and everything else.

 

Ahh..


I feel like buying spindles with the hubs intact would be cheaper and WAY easier..

 

yes that fork.

There will be an external electric actualtor you'll need to leave ON all the time. Then your good.

For manual to ADD you need an entire ADD diff. manual hub diffs won't accept the ADD tube from what i have read..so that that sucks.

And yes, you'd have to press is new wheel hubs..sadly.. MAJOR PITA to do that. I have read story after story about people breaking 10 even 20 ton presses.

Correct. Just make sure the ADD tub is locked and your good.

 

You can manually lock it using the prongs for the actual electric part that's how I did mine. Pins 1 and 5 left to right, just supply a 12v source and you can lock it
