Help! Front diff replacement on 2001 SR5 Sport

[nor_cal51501]

Hey T4R guys, I'm swapping my front diff 4.10 for another one with a 4:30. Here's my concern, I have a 2001 and I believe the diff I have to swap in is out of a 96-98 with the ADD air lines. First off, what are the ADD lines? If I have read correctly my 2001 doesn't have these, or does it? Is the front diff compatible with my car?

You should be able to swap the actuator from your current 4.10 diff to your new 4.30 diff.

Yep, just swap the ADD tubes to your newer version. It requires loosening (4) very tight Inverted Torx fasteners, I don't recall the exact size.

Ok, so the differential will work I just need to swap the actuators? Are the airlines I hear people talking about the ones that go to the actuator? Or do they go somewhere else? I'm about to unbolt the 3 main bolts holding the diff in place and drop it so I wanna know before I get in too deep.
