I need to replace the rear bearings on a 400ex, I have the Axle nut
removed so far. Now could someone help with the next step? Looks like
i need a really long gear puller to get off the disc hub. Then The
Bearing carrier should slide out, Is this correct? What else will i
need to do? My plan is to replace the bearing carrier. Am i also going
to have to get special tools to get the carrier with bearings off the
axles?

Any help is appreciated.

If you have the axle nut(s) and clip removed, just smack the axle end with a
rubber mallet and the rotor should pop loose so you can pull it off. Now
just pull the axle out. With the axle removed you need to remove the clip
from the carrier (behind where the rotor was), them it should slide right
out.

Hope this helps,
SMC

A little added info, straight from the book...I'll skip the part about the
stopper ring on the axle nuts as you must've found that and removed it
already:

Remove skid plate.

Remove the brake disc/hub by sliding it outward.

Remove the O-ring from the inside of the disc hub.

Loosen the rear axle for max drive chain slack, remove chain.

Install wheel hub nut onto the right end of the axle to avoid damaging the
threads on the end of the axle.

Remove the axle by driving it out of the bearing holder in the swingarm
using a rubber mallet(as already mentioned by MOTO).

Remove the snap ring from the bearing holder.

Remove the caliper stay(mount that the brake caliper bolts to) and remove
the stopper bushing(it will usually fall out on its own so don't lose it).

Remove the O-rings from the bearing holder and stay groove.

Remove the axle bearing holder(carrier) to the left by tapping lighty on the
right side.

Remove the O-rings from the holder grooves.

When you're ready to put everything back together the book suggests new
O-rings with oil applied to them but we never did that and had no problems.
Also, the outside of the old(or new) carrier needs grease applied to the
outer surface of it too. One more thing, the snap ring goes on a certain way
as well...you'll see it says "out side" on it, well that's how it goes back
on(obviously). Need to apply grease to the inner surface of the caliper stay
too when re-assembling.

That's about it, it should be right into your hand by this point. Just a
buncha O-rings to keep track of is all, I'm guessing if they did their
intended job then bearings would never go but they do. Good luck!

Thanks Moto and Robbo for your help. I still can't get the disc/hub
off of the axle. My neighbor lent me his long puller, but it still
won't move. I might try heating it up while pulling. If all else fails
i'm going to have to cut it off and get a new one.

Thanks for your help

Is there a metal clip ring holding it? I saw this on an old Honda machine I
had.....

I thought there was some kind of clip holding it, but it was just 3
years of rust build up. A little persuasion with a large hammer and a
hunk of brass got it off. Thanks all for your help.
