Rear wheel bearings

Mine are shot with only 60,000km.
Do other people have this issue?

Any tips on getting the old one's out?

Only ? lol
Damn
That to a bike is like going around the world 11 times.
They probably already have been changed twice.
Getting them out is easy, if your wheel has a snap ring, make sure the snap-rings are out, my wheels have no bearing rings or clips.some rear wheels do.
Use a hammer and a chisel if you dont have bearing drivers of the right size.
Putting the new ones in is where you can screw up.
Dont drive the inner race, only drive the bearings in by their outer races.
Bearing driver or big socket needs to fit decently on outer race.
People beat them in with crescent wrenches and they still work, but do it right and
the bearing will live long and prosper.

I already have them out. It was pretty easy.
Looking for something good to press new ones back in.
I'm looking for the right size PVC pipe.

I doubt PVC pipe will be strong enough - they are a tight fit. If you can put them in the freezer for a couple hours first and better still if you have a small torch heat up the hub. Use a socket the correct size - the socket side not the flat side - easy to cut/damage the plastic seal on the bearing or hit the actual bearings or inner race - ruining or significantly shortening its life. Did you check the one on the cush drive?

The one in the cush drive is fine.
Only the disc side bearing is toast, but I'm replacing both.
If the cush drive goes, it's easy to replace.
I've used PVC to push bearing in before.
It depends on the thickness of the pipe.

60,000 KM is only 30,000 miles or once around the world.

That is a little early I think. Perhaps once when the wheel was put on they were pinched wrong?

I think I know why the bearing went early.
I love to change left turning power slides into a transition wheelie.
I'm sure the right side bearing is pretty stressed during this move.
But I don't care, I love doing it.

Use the old bearing to tap the new bearing in. Tap only on the outer race in a rotating pattern.

I don't know if the bearings are recessed in the hub, but if they are, and if you have access to a grinding wheel, grind a little off the outside edge of the old bearing to prevent getting it stuck in the hub.

This works for dual tapered wheel bearing outer races on cars and trucks as well.

And use a brass drift to drive out the old bearing. That will prevent damaging the hub.

Where did these pop-ups come from?

We're getting spammed on key words.

The one disk side bearing is recessed.
I found an old bearing race that I had in my tool box.
It will make a perfect drift. It's already a few thou. smaller.
