Simple as simple can be.

Remove diff cover.
Remove small bolt holding center pin.
Remove center pin.
Remove c-clips.
Slide out axle.

If you want to be picky, you can take off the wheels and drums, too. :D
 
step by step...

To remove a rear axle shaft,you need too..

1.Take tire and rim off,and the brake drum..

2. Remove the cover off the diff--10 bolts..

3. Rotate the axle until you can see the bolt holding the "spider" pin in the case..its usually an allen head or torx head bolt,or possibly hex head..they snap off easily,and can be a real bitch to get the remains out of the diff case!..(thats another whole page in itself--lets assume it comes right out easily)..

4.Remove the pin the spider gears are on...

5.Push in on the axle to be removed,so the "C" clip can be removed from the recess in the side gear..(usually falls out into the case by itself)...

6. Remove axle carefully--dont "drag" it over the outer axle seal,or the splines will tear it up..

7. Reverse procedure to install..


Pictures help a lot when doing this for the first time!--and posi rears use a bit different procedure,(dont take the spider gear pin out all the way!--and watch how the "C" clips go in--they fit 2 ways,but only 1 way is correct!!)-but the basics are the same..might be best to have someone who's done it before help,or practice on your "junk" axle until your familiar with doing it..:crazy:
 
Your K5 has 30 spline shafts so make sure the axle in the yard is 30 spline also. I think they switched to 30 spline sometime in 1988.

Its a rear end.
 
hmmm, not sure if i can get help or not, i really need to get help swapping in my front end still, hopefully that will work out, is it worth having a shop put in the axle shaft, or wait until i have sufficient help? what would you put first, swap shaft in rear, or swap out the junk front end for the good one?
 
id swap the rear axle shaft first. Then swap the front ends. Both take a bunch of time, but not hard to do. You dont need help with the rear axle shaft as much as you would need a helper for the front axle swap.
 
Axel shaft is real easy to do. I'd love to come and help you but I am on a 2week vacation and will be doing the body on my truck over the next few weeks.

Talk to DirtyJim, maybe he can lend a hand.


It is not worth the $$ to have a shop swap the axels for you. Do it yourself.

Also what year rear end did DirtyJim give you?

Doesnt matter both will be 30 spline after 88...

I used to believe that, too. Right up until I ordered a 30-spline locker for my '89 Blazer and had to send it back and pay a 15% re-stocking fee because it has 28-spline axle shafts. :rolleyes:

Never take anything for granted. Always physically verify.

Oh, and definitely do the rear shaft first. You can have that done in an hour or less. The front axle is a little more involved.

how so i think i will be tacklin this one my self, with you guys on the sidelines, and maybe a friend, but thats very iffy

Glen, unfortunately DirtyJim(dave) is on vaca till the first week of august, i`m not sure what rear end it is, only has 10,000 miles on it though
 
ok i got the shaft out of the other axle, it was pretty easy after i decided that the cross pin wasn`t gonna come out too, there was no way i could get it out, that doesnt effect anything right?...i couldnt get it to slide out so i took a hammer and driver too it and it ended up getting jammed in the back of the housing...i need to know the different things i`ll have to do with the rearend currently sitting under my truck now, the posi, and also what i have to do, to not do what i did, if that makes sense
 
Getting help!!!:haha: :haha: :haha: :haha: I usually wind up doing everything on my junk myself. For some reason help is never around when I need it. I have done engines, trans, and axles by myself.
 
anyone? it actually looks like i might have help on this one, but i`m not so sure he`s familiar with the posi....he told me he was gonna talk to a guy we know who is a mechanic, and just happens to be the non official PO of my truck, to see what he has to say about doing it....

Did you forget to take the cross shaft bolt out? You shouldn't need a hammer to get the cross shaft out. It usually just slides out if you reach behind the carrier and push on it with your finger. Then pull out the cross shaft and take off the brake drum and push axel shaft inward, then remove the c-clip. Then pull out the axel shaft. Pretty easy, I'll search for pictures.
 
Once you had the cross shaft bolt out the cross shaft needs to come up not down and into the carrier or it won't go far enough to remove the C-clips.
 
i got them out:confused: ....what i need to know now is how do i swap it into the posi rearend in my truck
