Use a new collapsible spacer and nut.
Do not use a impact wrench on the rear end!
Holding the flange while you tighten the nut (240 FT Lbs. APX to get the 15 inch lbs):

Checking for 15 inch lbs movement:
Drive Pinion Flange
Special Service Tool(s)
2-Jaw Puller
205-D072 (D97L-4221-A) or Equivalent
Companion Flange Holding Tool
205-126 (T78P-4851-A)
Companion Flange Replacer
205-002 (TOOL-4858-E) or Equivalent
Removal
1. Note:
The rear wheels (1007) and brake drums (1126)/calipers (2552) must be removed to prevent brake drag during drive pinion bearing preload adjustment.
Remove the rear brake drums/calipers.
2. Mark the driveshaft flange and pinion flange for correct alignment during installation.
3. Remove the four driveshaft bolts and disconnect the driveshaft (4602).
Wire the driveshaft out of the way.
4. Install an inch-pound torque wrench on the pinion nut and record the torque required to maintain rotation of the pinion through several revolutions.
5. CAUTION:
After removal of the pinion nut, discard it. A new nut must be used for installation.
Use the special tool to hold the pinion flange while removing the pinion nut.
6. Mark the pinion flange in relation to the drive pinion stem to ensure proper alignment during installation.
7. Use the special tool to remove the pinion flange.
Installation
1. Lubricate the pinion flange splines.
Use SAE 75W-140 High Performance Rear Axle Lubricant F1TZ-19580-B or equivalent meeting Ford specification WSL-M2C192-A.
2. Note:
Disregard the scribe marks if a new pinion flange is being installed.
Align the pinion flange with the drive pinion shaft.
3. With the drive pinion in place in the rear axle housing (4010), install the pinion flange using the special tool.
4. Position the new pinion nut.
5. CAUTION:
Under no circumstances is the pinion nut to be backed off to reduce preload. If reduced preload is required, a new collapsible spacer and pinion nut must be installed.
CAUTION:
Remove the special tool while taking preload readings with the Nm (inch-pound) torque wrench.
Using the special tool hold the pinion flange, tighten the pinion nut.
Rotate the pinion occasionally to make sure the cone and roller bearings are seating correctly.
Install a Nm (inch-pound) torque wrench on the pinion nut.
Rotating the pinion through several revolutions, take frequent cone and roller bearing torque preload readings until the original recorded preload reading is obtained.
If the original recorded preload is lower than specifications, tighten to the appropriate specifications for used bearings. If the preload is higher than specification, tighten the nut to the original reading as recorded. Refer to Torque Specifications in this section.
6. Position the rear driveshaft and align the marks on the pinion flange.
7. Install the four driveshaft pinion flange bolts.
8. Install the rear brake drums/calipers.
Pinion Seal
Special Service Tool(s)
Pinion Seal Replacer
205-208 (T83T-4676-A)
Removal
1. Remove the pinion flange. For additional information, refer to Drive Pinion Flange above.
2. Force up on the metal flange of the rear axle drive pinion seal (4676). Install gripping pliers and strike with a hammer until the rear axle pinion seal is removed.
Removing pinion seal:

Installation
1. Lubricate the new rear axle drive pinion seal.
Use Premium Long-Life Grease XG-1-C or equivalent meeting Ford specification ESA-M1C75-B.
2. CAUTION:
If the rear axle drive pinion seal becomes misaligned during installation, remove the rear axle drive pinion seal and install a new seal.
Use the special tool to install the rear axle drive pinion seal.
3. Install the pinion flange. For additional information, refer to Drive Pinion Flange above.

So this is the proper procedure for the 10.5" rearend? I have a 06 F350 SRW 4x4 that needs the pinion seal changed out. So I would have the Sterling 10.5" rearend?
Thanks in advance.

All those fancy torque specs and new crush sleeves are fine if you are setting up some new gears and bearings in a dry rear end but for just replacing a seal on the vehicle it is best and easiest to take the nut off, clean it up, put loc-tite on it, leave the old crush sleeve in and slowly run the nut down until there is a little drag on the yoke. Done! I know people with no experience will chime in and say I'm wrong but this will beat any other method and work fine for many years to come. The pinion bearings just need a little drag to assure they are snug. The pinion bearings wear a bit and the old crush sleeve has a little spring to it so with the combination of these two things you can easily attain a good drag after replacing the seal. Run the nut down slowly though and check for drag often so you don't have to back off.

You're absolutely right about destroying a rearend if you don't know what you're doing. I've always done the rearend work on my cars over the years. I've also installed ring and pinion gearsets. Here's the latest buildup I did for my 1970 Mustang.

My vent isn't clogged. The seal has been weeping a bit for a while and now is starting to leave drops on the ground after long drives. I have 120,000 miles. My dad's 06 F250 had the pinion start leaking at the same mileage. I just wanted to make sure that I had the 10.5 rear axle and that was the correct service info before I pulled the pinion flange off.
Thanks
Just do what I said in post 8 and everything will be fine.
