I am getting ready to replace a rear axle shaft seal. According to the manual the rear knuckle has to be removed to remove the rear axle.

Does the knuckle have to come completely out?
Are there any shortcuts in taking out the rear axle?

FWD or AWD?
I don't think a FWD has Rear Axle Shafts.
And yes the knuckle should be removed after the hub and bearing assembly is out of the way.

The only other way is to lower or drop the rear differential.
Neither way is particularly easy.

I recall on a 79 Sunbird it was cheaper to pay a mechanic to change the rear axle seal because the "special" socket needed was half the price of the job.

If I was doing an axle seal on my own Nox I think I would go through the rotor and wheel bearing.
It's a personal choice, it might take a little longer this way but I want to see the rear brakes and would put on new wheel bearing just because the old one is already off.
Of course then I would feel guilty and do the other side.

As for lowering the differential be prepared to remove part of the exhaust, and a variety of bushings and mounts.
The good news is when you slide the axle out of the rear diff, the seal will (or is supposed to) come out with the axle.
There is a retaining clip on the axle, use a new one for assembly.
When installing the new seal, clip and axle you will first feel some resistance.
A snap or click will be heard when fully seated.
Good luck, let us know how it went.

That was the way to do it. Only you dont have to take the wheel bearing off of the knuckle. Simply remove the caliper assembly and knuckle assembly to remove the axle shaft. All of the bolts are very assessable. I just did a quick soak in 50/50 mix of acetone and trans fluid and they came out nicely.

So far only a one beer job.

You don't have to drop the rear diff, to do it that way you will have to deal with the exhaust.
Which engine do you have??
The 3.6L has more to the exhaust and a larger fuel tank.

Go back and read this thread again, especially posts #7 and #8
Either way you do this is not particularly easy.

Is there a tool I need to get the CV seal out of rear diff?
I went through my Repair Manual and it shows both ways.
If you are just after the seal pull the brake rotor, backing plate, wheel bearing assembly, and knuckle.
Just like 24882 shows in his pic in post #8, much less components to deal with.

You will need a socket to remove the axle nut, a three bolt puller if the splines on the axle are frozen in the wheel hub, and a "suitable tool" to coax the axle out of the diff assembly.
The Repair Manual shows an approximately 2 foot pry bar as the "suitable tool".

Read the second half of post #7 again and go for it.
