Ok fellas I just pulled the a.d.d. front 3rd out of my 90 4runner and put a non a.d.d. 3rd with an aussie locker in its place but I'm have problems with the aussie feeling like it locks and unlocks at will and being its in the front its not so good.
I was not sure what to do with the vacume hoses and the electric line that hooks up with the vac hoses and I'am wondering if not pluging the hoses keeps sending a message to the front to lock?
Any help you can give me would be great but for now till I figure I'll pull the axels till I can get a good handle on this situation yea or nea will it help???

 

Do you have manual hubs? I doubt the vacuum hoses are sending any kind of signal to the aussie locker. There is a writeup on 4x4wire about going from add to non add.

 

If you dont have manual hubs, GET THEM. Assuming you dont, the locking feeling is binding in the front end whenever you turn the steering wheel. Since the outside wheel wants to turn faster than the inside wheel on a corner, it binds up since the locker wont allow them to turn at different rates.

 

Ahh, no, that's not true.
An Aussie locker is an *auto* locker, not a spool (a spool is what you're describing).
An auto locker will unlock when there is a difference in speed between the two wheels, that is it will allow the outside wheel to turn faster than the inside wheel on a turn, as long as there is NO torque (pressure) applied to the pinion, that is that you're NOT in 4wd.
When the vehicle is in 2wd, the locker will unengage during turns, although not as smoothly as a Detriot say.

I do have hubs and they are in free but still its locking and unlocking I belive and when I let off the gas you can hear the front a whine and popping and snapping when turning. I think I am going to pull the axles till I can find out whats wrong.

 

The only way that the diff can have anything turning in it then is even you're in 4wd.
Think about it for a second.
If your hubs are unlocked then nothing is turning from the hub to the diff, that is the axles are not turning.
If you're also in 2wd then the driveshaft is free.
So, this means that the only possible problem is in the hub, assuming that you are correct in that the hubs are free and you're in 2wd.

they seem to be I mean I can get under the front and free spin the axle but both of them spin at the same time so how can it be unlocked ?? Do I need to get a different set of hubs for a non a.d.d. to correct it??

 

so you have your ADD hubs then? Or are they Manual locking hubs?

ADD hubs are just a lockplate. Manual hubs, self-explanitory.

The spindles are the same ADD-Manual.

 

So you can spin the axles by hand with the wheels on the ground, correct ?
Can you also spin the front driveshaft, by hand, with the truck in gear and the wheels sitting on the ground ?
If so, then think about this, that means nothing is turning other than the hubs, when you're driving in 2wd.
The axles aren't turning. The driveshaft isn't turning.
Nothing in the diff is turning.
Correct ?
If all that is true, then where must the problem be ?
In the only thing(s) that turn when the wheels turn, that would be wheel bearings, hub, right ?


Fred

 

I have it on the ground and can only turn the axels with the drive shaft they will not turn by themselfs in first gear unlocked at the hubs

 

So you can turn the driveshaft, by hand, with the wheels on the ground and the tranny in 1st gear (I'm assuming a manual tranny) ?




Fred

 

correct yes its a 5 speed not sure if theres a differance in the manual hubs for a a.d.d. or non a.d.d. and if that could be the issue
