Pinion Seal Replacement - TJ/YJ
|
|
Submitted by WHTJP98

While under the 99 TJ looking for a rattle I noticed the front seal
was leaking really bad. Being I had a wheeling trip coming up I needed
to get this done before then. It is not that hard of a job. So here we
go.
Tools needed for this job are as listed:
- 1/4 inch socket wrench with a 6pt. 8mm
- 1/2 inch socket wrench and or 1/2 inch impact gun with a 1 1/8 inch socket
- pry bar
- flat blade screwdriver
- scraper
- hammer
- floor jack and good jack stands, but this is optional
1. Remove the four 8mm bolts that hold strap that holds the u-joint to
the yoke.
2. Remove drive shaft. You might have to pry on this. Once free move
shaft to the side.
3. Using either socket wrench or impact remove the pinion nut.
4. Remove washer and try to remove yoke off the spline. You might have
to used a hammer to tap it off.
5. Take the flat blade screwdriver and remove seal.
6. After seal is removed clean up the surface of any debris left behind.
7. I used 3M weather sealant on the back side of the new seal before
installing.
8. Tap new seal into place.
9. I like to look at the old seal to see what happened. In this case
the yoke had a grove in it. I polished out the grove so the seal will
live a long life.
10. After cleaning the yoke I put some silicon sealant on the spline
of the pinion and some grease on the yoke where the seal rides.
11. Install yoke and washer. You can reuse the old pinion nut or
install a new one. If installing the old one use some lock tight on it.
12. Tighten it down with a socket wrench as not to destroy the crush sleeve.
13. Reinstall drive shaft and install straps and bolts.
At this point the job is complete. You have the option of changing the
differential fluid or checking to make sure it's at the right level.
In my case I chose to change the fluid because I did not know what was
in there and I wanted to get any remains of debris that might have
got pass the seal out of there before it cause some gears or bearing
damage.
I hope this helps you.
And a bad day wheeling is still better than a good day at work.
