Chevy IFS Axle Flange Removal

Trying to figure out how this is removed...this is for a 3/4 ton front...my 1/2 tons fall out easily with a light tap of the hammer but my other truck I pulled on it with a slide hammer and it still won't come out...I'm afraid that the bearing might be seize to it...this it the flange on the axle where the cv shaft attaches...

I will assume you are talking about the driverside flange?

If you are willing to pull the differential out and tear it down (except for the pinion), then call me tomorrow during the day.

The passenger side is much easier and can not be done with a slide hammer. You must remove the extension tube at the 5 bolt flange. Slide the gear off the shaft and it will reveal a snap ring that must be removed with a sharp pick.

GM is having a problem with the snap rings in the 3/4 and 1 ton fronts. the snap ring is too strong and will not release from the diff. when you call GM, they will tell you to cut the flange off so you can seperate it and get a new axle flange.

I do have them loose on the shelf.

The only way I can get one that is really frozen in there , is to take the case apart and have it on a bench. It seems physically impossible when you have it apart, but it can be done.

That is a big shaft, have you ever broke one? I have never seen it.

Just curious how much? Are the 1500's and 2500/3500 stubs the same size? I don't believe it's frozen...I've always seen them have a round bull ring wire on them, instead of a snap ring....personally I've twisted the splines slightly, but this is running comp 37's....I will try to call tomorrow...work has been slammed lately....

It should be a spring clip that is supposed to live in the side gear. They just don't work well with the straight cut groove in the stub shaft. It doesn't always displace into the side gear properly, and you are forced to destroy it.

The 1/2 ton parts are 8.25, and the 3/4 ton HD's and up stuff is the 9.25, so yes they are different stub shafts. The 9.25IFS is a high pinion version of the GM9.5, and shares many parts including the spline counts.
