Thumbs down Front Axle Seal Replacement

I am stuck with my Front CV axle disconnected, and I cannot get the inner Output Shaft broken loose. I have tried hitting it with hammer for almost an hour, as well as prying it.

ANY suggestions on how I can get it removed so that I can replace the Output Shaft Seal (Front Axle Seal - Driver's Side)?

Do you have access to a slide hammer? That is what alldatadiy says to use.

I do not have a slide-hammer, but that's a good idea, if I can make it fit in there.
I did try using a ratchet-strap setup, connected to the wheel while I beat on the other side, but no joy

I have used A length of chain before. Bolt chain to inner Output Shaft in two places make a loop in chain. Insert A length of bar stock or crow bar in loop snatch slack out of loop,kinda like using A poor mans slide hammer.

Question

Thanks to all for the help! I got the Output Shaft out with a gold chisel and a machinist's hammer. I tore up the first seal, and bought two more just in case.

I got the new one in, but did not seat it so the rubber is plush with the diff.

Before I drained the Front Diff and started this ordeal, I noticed a whine, and some mild binding. I got over a quart out of the Front Diff, so I figured I dealt with the seal in time.

GOOD NEWS: the Axle Seal seems to be holding-up after a test drive and 4WD driving

BAD NEWS: I still feel/hear the front driver's side whine on acceleration!

Do you guys think it's the bearings? Did I just do a s#*! job?

THANKS IN ADVANCE:rockin

does the whine go away by chance if you swerve to right or left? If it does its usually thats a sign of bearings.

I have not tried that, but I will. I am about ready to take it to my Wrench; which I really cannot afford.

I woke up this morning to check on the axle seal to find a small puddle of 75w140 Royal Purple!

I have one more Axle Seal left, but I am thinking I should give it to my Mechanic.

You guys are AWESOME! I really appreciate all of the help so far.

I am wondering if I should have seated the Axle Seal so that the edge of the outer rubber was flush with the differential?

Make it easy on yourself and if you cant it out with a slide hammer. Its only 10 bolts and the front diff can be dropped down. You can have the diff out in about 30 minuts easy. Then slide hammer the hell out of it. They get stuck all the time.

Toypuller,

I have a few questions:

1. Do you mean the entire Front Diff, or just the Driver's Side Half of it?

2. When I install the new seal, does the rubber edge need to sit flush with the Diff?

3. Do you thinking the whining I am experiencing on acceleration just has to do with the seal, or is it the bearing?

Thanks in advance.

I have posted some more pictures of the carnage. I can honestly say that for me, this has not been easy. I had to grind down the burrs I mad while prying out first the original seal, then the one I tried to install that got hung-up, with my Roto-Zip!

I used a 2" piece of threaded pipe with a cap, the other end taped with electrical tape, an beat it in with a machinist's hammer.

I think that I may not have driven it in far enough, but I am not sure that is what is causing the Front End Whine on acceleration.

I first noticed the Front End Whine after I knew that my Diff was leaking gear oil, and directly before I embarked on this nightmare Front Axle Seal replacement.

I do not want to admit defeat, but if I can't fix this, I will have to fork-out a few hundred bucks or more to my Mechanic and more importantly wait until he can get me in.

That picture of the Seal with rubber sticking-out was my first attempt. The second attempt, I left about an 1/8" of the rubber sticking-out because I remembered reading that the Seals are easily damaged and bent, if compressed too far.

I am guessing it should look just like that picture, without the rubber sticking-out of the Diff?
