Need some diff help!!

[lx4life]

I talk to jarek m a ton, but I am still having diffcult time getting the inner shaft out, i think I might have broken something cause that thing won't come out. I really dont want to bother Jarek anymore so thats why i am coming to you guys. I have been hitting the hell out of it, but not really applying upward pressure since i dont know how would accomplish it.:twak : There has to be somthign holding it in there maybe a clip or something. I have attached a picture of what i am talking about the cicrcle is what I am having problems with. Is the half shaft(black piece) two different pieces which one is suppose to come out or does all of of come out.

[HUMTECH]

Trya prybar with outward pressure on the shaft and hit it straight in towards the diff with a big hammer. If it dont come out you will need to split the case and ry to pop the clip off he end of the shaft.

[HUMTECH]

Hitting it straight back into the diff sometimes will center the retainer and allow it to pop out

[lx4life]

How do I split the case? I am new to this but love learning new things when I can. Still kinda confused on the prybar thing where do i put teh pry bar to aplly the upward pressure plus be able to hit the shaft or am I suppose to hit the prybar I swear I am getting stupid by the minute.

[HUMTECH]

Pry between the mount and the axle flange.

[lx4life]

ok gotcha! I really think its stuck in there, but I will try again tomorrow. does it need to be unbolted from the diff. before I hit

[HUMTECH]

Nope, it has a retaining ring that seats in a groove on the end. If that ring expands makes it very difficult to get out

[lx4life]

Well i tried again today I think I am going to break something, I really need to see a breakdown instruction or something that hitting the shaft with a 8lbs hammer is kinda scaring me cause I really think I am going to break something. I am probably going to get a slide hammer so it even, I have heard you have to buy new rings, man this doesn't make since I would think there would be a inspection hole to where we can gain acesss to the pin in the spider or retaining clip.

At the end of the shaft there is a spring that prevents the shaft from sliding out, you need to apply outward pressure on the shaft to get the spring inside the diff to align and then give it a hit with a 2.5er. Some springs don't come out in one piece there for hawing a new set handy is nice, my came right out, looks like yours are a little more stubborn that's all

This is a different application but the end of the spline looks same #1.

[jarek m]

#30

YOU ARE THE MAN JAREK I WAS REALLY TRYING NOT TO BOTHER YOU!!!!! THANKS SO MUCH, its just that these things are so expensive to replace if I break it and I really don't want to go to the stealership and have them do it, cause I could use that money for aftermarket parts you know what I mean. This iste is one of the best around, I have to work until tomorrow afternoon(32hr work day) so i will try again tomorrow after work

No thanks...I've got a copy of the GM EPC; I'm just always on the look out for an updated version.

What version of AllData are you running? I had a copy of AllData before I snagged the EPC...I can see from your post that the image quality of their diagrams has improved dramatically. The version I had was older and many of the pictures looked almost hand-drawn.

Here's the same diagram from the EPC, they're almost identical:

Hi what is EPC?

[HumminNBoatin']

I used a slide hammer to get mine out. However keep in mind if you break that retainer spring you need to split the case to get the broken pieces out. I broke the one on the long shaft when installing my front locker.

It's the Snap-On/Proview software that GM dealers use in their Parts Departments.
