Replacing front pinion seal.

[JGoss]

Does anyone have any tips or tricks to replacing the front axle pinion seal? Is that a loaded bearing or do you just tighten it for all your worth?(What dealer suggested??) I would hate to pay the dealer a $100 deduct. for the warranty work, when I can do it for $18(cost of new seal) Any info would be great, thanks.

This is from the 06 FSM.



1. Mark propeller shaft and pinion flange (1) for installation

reference.

2. Remove propeller shaft.

3. Remove hub bearings and axle shafts.

4. Rotate pinion gear three or four times.

5. Measure and record torque to rotate the pinion

gear with an inch pound torque wrench (2).

6. Hold pinion flange (1) with Flange Wrench 8979 (2)

and remove pinion flange nut and washer.

7. Remove pinion flange (1) with Pinion Flange Puller

8992 (2).

8. Remove pinion shaft seal with a seal puller or slide

hammer mounted screw.





1. Install new pinion seal with Installer 8882 (2) and

Handle C-4171 (1).

2. Apply a light coat of teflon thread sealant, to pinion

flange splines.

3. Lightly tap pinion flange onto the pinion, until a few

threads are showing.

4. Install flange washer and new pinion nut.

5. Hold flange (1) with Flange Wrench 8979 (2) and

tighten pinion nut until pinion end play is taken up.

6. Rotate pinion flange (1) several times to seat bearings.

7. Measure pinion Torque To Rotate inch pound

torque wrench (2) and compare it to recorded measurement.

Tighten pinion nut in small increments,

until pinion Torque To Rotate is 0. 40-0. 57 N·m (3-5

in. lbs. ) greater than recorded measurement.

8. Rotate pinion several times then verify pinion

Torque To Rotate again.

9. Install axle shafts and hub bearings.

10. Install propeller shaft with reference marks

aligned.

Dealer near me been doing them for less then $100 bucks and the two guys I know that got them done waited on them while they relaced them.

If you are not too familiar with differentials, bearing pre-load, and theory it might not be a good idea to tackle this on your own. These can be done in 10 minutes by a pro. If you get it wrong the consequences are huge. I suggest using a differential shop. I charge $50 to do the job-Seal,oil,and labor in my shop. If you don't have a reputable shop in your area PM me and I will walk you through it. You will need a strong 1/2" impact gun, 1 1/4" socket, long T40 socket, a puller for the yoke, and red loctite at the least.

Good luck.

Can anybody help I had warranty work performed on my 03 1 ton 2wd 11. 5 american axel because of a whine I thought might cause future problems. It turns out it's worse at coasting speed between 30 and 40 twice as loud. The service crew replaced pinon bearings and supposedly rechecked all the tolerances? any ideas?

They didn't get the pinion back in the same relationship to the ring gear as it was before. You need to take it back to the place that did the work and demand that they do it right. bg
