GM Tech (Cam) :

Hello, I'm Cam. Please include all the details about your issue so I can accurately advise you. I cannot see your vehicle so please be detailed.

GM Tech (Cam) :

You are changing the front axle shafts or thefront diff?

Customer:

I am replacing the bearings on theright side of the differential

Customer:

i have unbolted the cv joints

GM Tech (Cam) :

Ok, front diff?

GM Tech (Cam) :

If so then once they are out, there are 2 nuts on the right axle tube, remove those.

GM Tech (Cam) :

REmove the front drive shaft.

GM Tech (Cam) :

Remove the 3 bolts that hold the steering box to the frame after turning the wheel all the way right and popping the pitman arm off the relay rod.

Customer:

thats where I am stuck it wont come out

GM Tech (Cam) :

what will not come out/

GM Tech (Cam) :

sorry I guess I am typing too fast.

Customer:

the cv joint that I disconnected from the unit that enngages when in 4 wheeel

Customer:

6 bolts

GM Tech (Cam) :

Ok they are set into the flange a but, use a hammer to hit the housing a bit then they will push back and you can drop them off the diff

Customer:

done now i need to get to the bearing

GM Tech (Cam) :

OK.

Customer:

o

Customer:

how do I get the bearing out

GM Tech (Cam) :

is it in the axle tube?

GM Tech (Cam) :

Or the diff side bearing?

Customer:

inside the diff

Customer:

diff side

GM Tech (Cam) :

do you have the whole diff housing out then

Customer:

no still on vehicle

GM Tech (Cam) :

Ok you need to take the whole housing off then split the case to replace the right diff carrier bearing

Customer:

so there is a lock ring inside the housing?

GM Tech (Cam) :

the inside roller bearing is pressed on the carrier so there is no way to remove it while in the truck.

Customer:

would it be possible to get a diagrahm of the inside of the diff

GM Tech (Cam) :

But if I may, it sounds like you are talking more about the right axle shaft bearing.

GM Tech (Cam) :

What exactly is happening?

Customer:

I have a severe leak right behind where the axle goes into the ddiff

GM Tech (Cam) :

Thats the axle seal then, not the bearing on the diff.

Customer:

the bearing must have collapesed because I hear grinding

GM Tech (Cam) :

So once you get the cv shaft off, and the 2 nuts, remove the wiring and 5 bolts that hold the axle tube to the diff.

GM Tech (Cam) :

Then pry down on the diff and work the axle housing off.

Customer:

ok the axle seal do Istill need to remove the diff

GM Tech (Cam) :

no, not the whole diff, just the housing that holds the front axle actuator.

Customer:

can i send you a picture

GM Tech (Cam) :

Full Size Image

Customer:

part#58-59 are where it is leaking

Customer:

part #58-59 is where it is leaking

GM Tech (Cam) :

Ok you told me right, that is left.

GM Tech (Cam) :

So this gets easy, hit the back side of that flange with a hammer HARD to pop it out.

GM Tech (Cam) :

and if that little bearing is bad you can use a slide hammer to remove it and pound a new one in while in the vehicle.

Customer:

i apologize looking wrong side it is part 2-3

Customer:

can i still pop it out

GM Tech (Cam) :

Ok so take the 5 bolts out and all the parts 1-16 come out then you can remove a snap ring on the end of the shaft under there and slide the axle out .

GM Tech (Cam) :

only with the whole housing on the bench.

GM Tech (Cam) :

the whole right side axle tube housing I man.

GM Tech (Cam) :

mean.

Customer:

ok so no way to slide part 1 out without taking whole diff out correct

GM Tech (Cam) :

There are some that say you can, but then parts fall apart and you would need to remove it anyway.

Customer:

ok drained oil remove 5 bolt disconected acutator and the two bolts to the frame

GM Tech (Cam) :

now just on the diff side of the housing, pry down do the whole right side comes down.

GM Tech (Cam) :

Then slide the axle hosuing off.

GM Tech (Cam) :

You need to pry down enough so the right axle tube clears the studs.

Customer:

sorry Ihave it out thanks a much,
