nope...

forget all that.

best way is to just ditch the whole ADD assembly all together.
'
simple actually. you just need a couple of parts from a 4runner or pickup that didnt have the ADD to begin with.

then all you do is replace that axle housing, axle stud. discounnect a couple vacuum lines and you're in like flynn.

i broke my ADD inner axle. that's what happens when you are in double low-low and you bounce the front tire and land while in mid throttle.
'
i had a pix of the axle where it broke and it looks like it had a like 45 degree rotation before it sheared off.

i still have shift, albeit, i have to stop. but the inner axle is thicker and i dont have to worry about vacuum lines going out...
