The trouble was quite clear after we removed the seal.

As the right front bearing was severely damaged, we attempted to cut it out out with a Dremel.

We did manage to cut a big notch out of it, but Jack had a unique method of getting purchase on and driving out the race.

Here are the parts from the front.

All the removed parts.

The rear bearings don't look bad...but how could I tell?

Don't forget the Moly 60 every time you reinstall the rear wheel!

This is what the ST1100 looks like with both wheels off.

Here you can see the distance collar after I notched it.  That should make bearing removal a bit easier in case the toolkit isn't available next time.

Also, it appears to have some tool marks on it...suggesting those front bearings had been previously replaced.

While at it, I replaced the damaged (decal hides it somewhat) front fender.
