Here's the FSM...

PINION SHAFT SEAL

REMOVAL

(1) Raise and support the vehicle.

(2) Remove wheel and tire assemblies.

(3) Remove brake rotors and calipers. Refer to

Group 5, Brakes, for proper procedures.

(4) Mark the propeller shaft and pinion yoke for

installation reference.

(5) Remove the propeller shaft from the yoke.

(6) Rotate the pinion gear three or four times.

(7) Measure the amount of torque necessary to

rotate the pinion gear with a (in. lbs.) dial-type

torque wrench. Record the torque reading for installation

reference.

(8) Using Holder 6958 to hold the pinion yoke,

remove the pinion nut and washer.

(9) Use Remover C-452 and Wrench C-3281 to

remove the pinion yoke (Fig. 6).

(10) Use a suitable pry tool or a slide hammer

mounted screw to remove the pinion seal.

INSTALLATION

(1) Apply a light coating of gear lubricant on the

lip of pinion seal. Install seal with Installer C-3972-A

and Handle C-4171 (Fig. 7).

(2) Install yoke on the pinion gear with Installer

W-162–D, Cup 8109, and Holder 6958 (Fig. 8).

CAUTION: Do not exceed the minimum tightening

torque when installing the pinion yoke retaining nut

at this point. Damage to collapsible spacer or bearings

may result.

pinion gear.

Tighten the nut only enough to

remove the shaft end play.

(4) Rotate the pinion shaft using a (in. lbs.) torque

wrench. Rotating torque should be equal to the reading

recorded during removal, plus an additional 0.56

N·m (5 in. lbs.) (Fig. 9).

(5) If the rotating torque is low, use Holder 6958 to

hold the pinion yoke (Fig. 10), and tighten the pinion

shaft nut in 6.8 N·m (5 ft. lbs.) increments until

proper rotating torque is achieved.

CAUTION: If the maximum tightening torque is

reached prior to reaching the required rotating

torque, the collapsible spacer may have been damaged.

Replace the collapsible spacer.

(6) Align the installation reference marks on the

propeller shaft and yoke and install the propeller

shaft.

(7) Check and fill the gear lubricant. Refer to the

Lubricant Specifications for gear lubricant requirements.

Remind me to read up on how and to perform to do an engine overhaul before replacing the oil filter or spark plugs.

Yeah call me a troll due to doing things correctly... :doh2:

SO spec calls for 6-8in/lbs.

If you have a good assembly (maybe just leaking).
You follow your instructions, no matter where you got them from.
Your Pinion preload is at 6-8in/lbs to start.
You add 5in/lbs as your FSM or what ever you are referencing states to do, as its not Dana/spicer, they state to set preload without the carrier.

You are now at 13in/lbs (and only if your perfect and thats very difficult to set within a inch or two, so likely even more). Yep thats the right way to do it.

Its only over by 5in/Lbs+, 70-90% over what is recommended. Can you do it this way. Sure. Will it work, it "should', but will this assure that your still in the correct recommended range of specifications for your pinion preload, Nope... can this cause premature bearing failure, Yep.

Just like changing your oil. You can suck it out. But is this the right way to do it, nope. Or lets do brakes, but just pads. No need to turn the rotors right?

SO now troll = someone who wants to recommend the correct way to do something. Not some halfa$$ed way.. Got it.

FYI that wasn't directed at you.
