How do I replace Dana 30 pinion seal?

[Irun]

This thread has interesting information, but very conflicting to what I’m walking through when looking to change my Yokes to 1310 from 1330.

It’s a locking 1 time use Nut on the pinion (my slang “locking”, 1 time use), you should never re-use it, so marking does no good? Or does Jeep somehow have a nut that is reusable different than most others?

To measure the pinion torque in IN LBs you have to have the carrier etc and the axles out, not just the axles. Turning the pinion with the carrier in tells you nothing about preload of the pinion. At least that’s the detailed information I’ve been provided, and trust completely.

These are all “doable” methods and within ….sure that may not cause a problem?

I know all that sucks to do, but the only way to do it and know it’s actually done correctly, is pull all that, use a new nut etc, correct?

Iv'e done what the FSM says for removal, which is:


SEAL - PINION
REMOVAL
(1) With vehicle in neutral, position vehicle on
hoist.
(2) Remove brake rotors and calipers.
(3) Remove propeller shaft from the yoke.
(4) Rotate pinion gear three or four times.
(5) Record rotating torque of the pinion gear with
an inch pound torque wrench, for installation refer-
ence.
(6) Hold pinion yoke with Wrench 6958 and
remove pinion nut and washer.
(7) Remove pinion yoke with Remover C-452 and
Wrench C-3281 (Fig. 37).


There is nothing mentioned about removing the carrier, which isn't needed. A new nut is!

Locking ability degrades on a locking nut after 1st use, red and blue loctide can compensate for that.
