How to: Deleting ADD system

Total fallacy that has been spread by RST trying to get people to spend more money when they do the FJ tcase swap.

This is the correct answer.

 

I have a ~3” lift with a diff drop. Are you saying the cvs don’t mind the higher angle?

 

Here’s my diff after pulling the ADD stub out. This is a 2015 4Runner front diff and from what I can tell it is the same as a Tacoma front diff. Do I need to remove the metal retainer as well or can I just bolt the non ADD shaft/tube to the diff? It looks like it is just pressed on there. Is this an oil baffle that was added on the 5th gen 4Runner diff?

 

I wrote a bit about this in my ARB install DIY. https://www.tacomaworld.com/threads/front-arb-air-locker-diy-install-thread.692979/

As long as the non-ADD part fits without contacting this, and I assume it should as now it's just a straight shaft, you can leave it in. It's a retainer deflector that possibly stops over travel of the ADD clutch sleeve and also has tabs to deflect oil from getting into the breather.

 

Thanks for the information! I’ll do a quick dry fit before I do final assembly with sealant.

Shouldn't you be swapping out that roller bearing for the ECGS (sleeve bearing)?? while its right there in front of you!??!

 

Already did that, the ECGS bushing is on the drivers side.

 

That's not the problem one because it carries the intermediate shaft and not the end of the heavy, dangling cv like on the driver's side. Having said that it's the same bearing so the bushing would fit. If you swap to an ARB there's bushings on both sides of the carrier, no bearings. But that one is just fine.

 

I am currently doing my add delete on my 06 and I’m not finding the same wire colors at the 4x4 ecu , need to know what 4 wires do I pare to one another ? I found some info but colors are not the same .

 

You shouldn't have to mess with any wires doing this mod.

 

He might be talking about the dash lights for 4WD

 

Yes lights in the dash exactly

 

Add delete complete in the front diff wiring tied up , transfer case in , all that’s left is to let silicone sit over night and fill diff , t case and trans .

 

There should be info where to tie into those lights on the FJ case thread, this mod has nothing to do with the FJ case install. Here is the info you might need

Late to the party.....TLRL....But why isn't there just a cable system like jeeps have? I had this on an old Jeep and it worked pretty well.....Seems like just adding some contacts would work.

Exactly , wiring done lights work . Thanks once again 6gear .

 

I hated it on my LJ, constantly had to get under and adjust the dumb linkage
