If I understand right, there is no clip to remove in the diff. on this axle to pull the shaft. Am I right?
Also, while I'm in there, should I go ahead and replace the bearing also? This truck is just about to hit 200,000 miles. If the axle moves fine, could I be okay to just replace that outer seal?

Okay, now the basement garage smells really nice. Tabitha is going to kill me when she gets home because the Trooper and the gear oil stench are in her garage bay.
I've made it this far, and can see where it shouldn't be too hard to replace the bearing while I'm in there.:
All the brake parts were pretty oily, and will need a good cleaning:
Now a couple of questions. First, how does all of this come apart? Is the bearing pressed onto the axle shaft, or should I be able to slide the shaft out of this assembly somehow?:
And next question: Some of the splines on the axle shaft look a little boogered up. Is this too bad, or will it be fine for awhile like this?:
beagler wrote:Thanks Jerry. I have a 20 ton Harbor Freight shop press, but it sounds like that might not be enough to get the bearing off. If that press would be sufficient, how do you set it up? I've used the press to press bearings in and out of Ford Focus spindles, but that was pretty easy to set up. I'll give you a call in the morning to see about getting the seal, and if you don't get a chance to explain here, I can ask you then how you set this up on the press to get the bearing off of the axle shaft.
It sounds like, at a minimum, I can take care of the plugged vent and change the seal. I didn't realize that the gear oil wasn't supposed to make it to the bearing (and had figured that the bearing was lubed by the gear oil). So this is the seal where the oil is getting out?:

THE AXLE COMES OUT THE SAME WAY WITH THE FOUR RETAING BOLTS GOIGNTHRU THE BACKING PLATE TO THE AXLE HOUSING,
Is the seal near the bearing on mine or is it near the diff?
AFTER GETTING THE AXLE OUT YOU WILL SEE A VERY LARGE NIT THAT SCREWS ONTO THE AXLE, THIS NIT HAS TO COME OFF AND THEN THE BEARING, AND THE SEAL IS IN THE OUTER BEARIGN HOUSING, AND THERE IS ALL SO A SEAL IN SID ETHE AXLE HOUSING THAT SHOULD BE REPLACED WHILE THE AXLE IS OUT,
Where can i get a new seal?
I HAVE THOSE SEALS, AND NEW AXLE LOCK NUTS
When putting it back together do i just slide the axle back annd its good or do i need to remove the diff aswell?
ONCE THE SEAL AND THE BEARINGS ARE BACK ON THE AXLE JUST SLIDE IT BACK INTO THE HOUSING, NOT NEED TO PULL TH E DIFF OUT,
THE ONLY THINK YOU HAVE TO DO IS GET THAT BIG NUT EXTREMLY TIGHT
TURN THE AXLE UPSIDE DOWN AND HOLD THE NUT IN A VISE AND THEN TURN THE AXLE ITSELF WITH A BAR PLACED BETWEEN THE STUDS AND GET IT AS TIGHT AS YOU POSSIBLE CAN , IT IS SUPPOSED TO BE 200. FT LB,S AND HAS A LOCK PLATE BEHIND THE NUT , IF IT COMES LOOSE THE AXLE AND WHEEL CAN COME OUT OF THE HOUSING.

cyberdog wrote:Took the axle out on mine and it was pretty easy Is there any other seal on this side or is it just the one in the axletube ? Anything behind the bearing ?
Ok so there is a outer oil seal behind the bearing and then the one on the axletube Does anyone know the sizes of those 2 on the 1987 Trooper with the 10bold axle ?
The outer seems to hold tight since when i have been washing it there hasnt come a drop of water or anything through that seal.
But the one on the tube seems to not hold tight since between the bearing and that seal there was a ton of oil/grease.
Looking at the below pic i need 16 and 40 right ?
THERE ARE TWO SEALS, NO 40 IS THE INNER AXLE TUBE SEAL AND THE NO 16 IS THE OUTER AXLE SEAL , THAT HAS TO HAVE THE ASSY DISSASEMBLED TO GET TOO. JERRY

I have the useless Haynes manual which shows the same exploded view. But when removing my axles, it appears that the axle bearing is held on with a big nut, locked in place by tab. I also understood the bearings to be tapered roller bearings instead of ball races, as seen in those photos.
This means their fit is adjusted by shims between the bearing housing and the axle tube. True?
sanramonrover wrote:Hey Jerry,
Thanks for the confirmation! I just checked with our Canadian Isuzu (GMC) supplier who tells me that he can GET the necessary parts on order. Now that I have part numbers I'll check Costa Rican suppliers.
I would guess that it is not possible to grease that bearing without removing the carrier, or that big nut??
cyberdog wrote:Have removed right rear brakes and axle now. The brakeshoes and everything else was coated with a layer of oil and grease I have cleaned up the shoes and washed the axle with high preassure washer so its all clean now.
Ordered new seals from JLEMOND so cant wait to get them home to change them. ALso i have ordered a new brake cylinder to replace the old since i already have it opened up
Big nut removed. Do i need to press out the bearing or is there any other way to get it out ? I am guessing the seal is behind that bearing ?
YES YOU WILL NEED TO PRESS OUT THE BEARING TO GET TO THE OUT BOARD SEAL.THESE ARNT GENERLY REALLY IN THERE TIGHT LIKE THE 12 BOLT BEARING COLLAR , BUT THEY OF COURSE CAN BE ,
USE A PIECE OF STEEL TUBING TO DRIVE THE BEARING BACK ON TO SEAT IT
A big nut
Old seal still in place but have cleaned it up. This area was full of oil/grease mixture.
Just a pic looking inside the "axletube", Old seal still in place. Funny mirror effect inside.
Heres a pic of the small wrench used to remove the nut that holds the bearing on the axle. Its sitting beside a 19mm one The big one is a 2 1/4" wrench.
