i was wondeing how hard it is to swap from them auto hubs to manual and what are the benifits from it and is it really worth it to swap them

 

Easy swap you'll need 4 54 mm nuts and 2 lock washers. Dealership is the cheapest place I've found these parts. Definitely beneficial auto hubs are garbage. Just take off auto hubs install nuts, set wheel bearing preload install lock washer and nut, that's it.

 

ok anyone got pics how to swap them is there any benifit from these or not really i dont wheel my truck hard maybe do down a few trails thats it

 

The benefit is that you can use 4x4 in reverse without the hubs dissengaging. I'm not sure of all the technical differences between auto hubs and ADD, but with manual hubs, when they are dissengaged the CV's aren't turning so you have less wear on the front driveline and rolling resistance overall. In terms of strength, I'm not sure if there is a difference between any of them.

huh wonder why they dissengage in reverse

 

the link wont open for me

 

Stop it.

 

If the link isn't working for ya Google 93 Toyota pickup service manual.

 

I'm willing to bet you have ADD and not auto hubs if the pic in your avatar is the one you're working on. If it's ADD, all you have to do is replace the drive plate with the locking hub bodies and put the locking dial and plate onto the hub body. ADD doesn't unlock in reverse, so the only advantage you'd get is less rolling resistance and less wear and tear on your front axle with the hubs unlocked.

 

im confused whats ADD

good info wabbit but i have no clue how to swap them and what part is what

does anyone have pics on how to swap them out

 

I get it. Guess I will be getting a set of IFS manual hubs, hub nuts, and washers for the Runner.... Do I do this before or after 3.4 swap...? Hmmm....

 

Before the 3.4 however after the 4" body lift, and roughly the same weekend as the two 12" subs in the rear. . .

 

i tried searchin and not finding a how to or anything like that

 

The first thing you need to do is, like previously stated, find out if you have auto hubs or ADD. You can do so by following the link that wabbit provided.

 

Do I do the body lift after or before the lowering kit and ground effects kit?

 

im so confused right now about this ADD and theauto hub its says 89 could either be auto or ADD so how would i know which one i have sorry for being dumb but im confused

 

My '88 Runner says Auto hub on the hub face. It looks like a manual hub, except no dial to turn. ADD, I believe, has a disconnect on the differential(driver side axle tube, close to the gear housing) itself. It has some vacuum lines running to it. It will not have a non-dial hub like I described earlier. Automatic Differential Disconnect is, again, I THINK, what it stands for.

Can someone verify or correct this?
