you need to pull the axleshafts out a little bit....

do you know what you are doing at all or no? if not, i recommend gettign a factory service manual and studying it... it isnt that hard... but you have to have some base of mechanics

i know some what of what i am doing i just cant figure out how to pull the axle shafts out

4 bolts at the end of the housing. Remove them. The axles should slide far enough for you to remove the 3rd.

unbolt the 4 bolts on the back of the wheel assembly. You may or may not have to remove the brakelines as well. Leave the tire and wheel mounted, and jack the truck up so there is just a little bit of space between the tire and the ground. With a little pulling, the axle shaft should slide right out.

Leaving the tire and wheel on does a few things for you.
1) gives you something to get a better grip on when pulling, you might have to put some effort into it.
2) in case the truck shifts and/or falls off the jackstands, the tire will keep the truck from falling very far
3) now you don't leave the axle hanging halfway out of the axle tube, resting, and possbly damaging your axle seals. The tire will hold the axle shaft centered (for the most part) in the seal. I'd go ahead and replace them anyway, while you've got it apart, but a lot of people don't.

Haha, you give a little more detail than I do.

ok i ot the truck on a lift and its just a front ifs differential and i have that complet differential out of the truck and on the table. but like i said i cant get those shafts out.

KDXSR5 · « **Reply #8 on:** May 03, 2008, 10:06:27 PM »

Ok... so you are changing out a FRONT IFS diff? Or are you changing out the rear diff? I am confused. Or are you asking how to get the actual gears out of the 3rd member sitting on the bench?

ok, whole different story. Does the spare diff you have sitting out have the stub shafts already in it? If it has a flange on both ends with 6 bolts pressed through it, then yes it does. If that is the case, all you have to do is take off the 6 nuts on either flange on the diff that is still in the truck, and use a long screwdriver or pry bar to push the flange off the CV section of the axle. pull the diff, put the other one in, and reverse the process. When you put the other diff in, make sure the axle ends are above the diff, and not hanging down, it is a lot easier to get them to line up when you're bringing it down, than pushing up.

If you need to pull those stub shafts out of the diff, you've got one of two options. One is to stick a large screwdriver between the diff and the flange, and pry it out. It'll be tight, but then it'll pop loose, there is a c-clip holding it in the diff. The other option is to take off the diff cover, and find the ends of the axle shafts, and tap/push them out from the inside.

You could also take a CV, slide it over the 6 bolts, thread all 6 nuts on a few threads, and give it a good yank, essentially using the CV as some sort of slide hammer. Make sure you've got the diff held down real well though, it'd suck to pull that onto your foot

*EDIT*

This is a pic of the backside of the flange, which is supposed to be attached to the stubshaft shown below. Obviously in my case it wasn't, but just an FYI, I got that stub shaft out of there by gripping it with the visegrips, and prying against the visegrips and the housing with a screwdriver. It takes a little bit of effort, but you can pry it out.

do you like the sawsall?

BABYTOYOTA · « **Reply #15 on:** May 03, 2008, 10:36:41 PM »

i love that beast

BABYTOYOTA · « **Reply #16 on:** May 03, 2008, 10:39:11 PM »

a question for blackdog. when i put that shafts back in what do i do?

KDXSR5 · « **Reply #17 on:** May 03, 2008, 10:42:45 PM »

Ok, if the tires hit anything, hit what the tires are hitting with a hammer. If the hammer does not keep them from hitting, cut it off with the sawsall and either patch the hole you made or clean/paint the edge of the sheet metal you cut. If you don't want to do these things, you could install a body lift, or crank the torsion bars and use an extended shackle in the rear.

BLACKDOG · « **Reply #18 on:** May 03, 2008, 10:45:10 PM »

Line it up, and tap it back in there with a hammer. You'll find that those C-clips will give pretty easily, and it'll pop right back in.

33"s with an 1 1/2" lift? They should fit. Put them on, and make sure you can turn them completely, both left and right. You may have to hammer the pinch seam on the firewall flat, and you may have to do a little fender trimming, but probably not much

I'll be back on tommorow, and at home, so if you can't figure out the diff issues, I can take some pictures for you, and try to explain it better

Goodluck!
