Never use a punch or chisel to seat a bearing. A properly installed bearing should never spin but it should creep!! very slowly. Loctite can be acceptable in some applications. If you do not properly repair a spinning bearing race you will sonn have even worse problems.

I was not aware that a race should creep. Could you explain the reason for the creep?

Worn out drums allow the race to move, well really the hub part.

Over tightening of the bearing retainer nut, can in time, cause the race to start moving within the hub.

When that takes place, the hub and drum is finished.

To try and save the drum, is absolutely foolish.

Sometimes, like with the old vintage trailers that used small bearings, drums are no longer available.

If that's the case, then an axle replacement is necessary.

To avoid that issue, or to try to "beat the system" would be the absolute height of foolishness, once a race becomes loose in a hub.

Bearings, drums, races, axles, all can be bought.

Lives "CANNOT" be bought, at any price.

Once a race becomes loose, bite the bullet and correct the problem, properly.

Once a race becomes loose, you cannot, no matter what method you use, make sure that the race is "exactly centered."

That being the case, vibrations can quickly take place, causing further failures, faster than you think.

Safety procedures and practices, gives a person great comfort and a great distance from that human grave yard.

Lack of safety or ignoring it, shortens that distance, "FAST."

BE SAFE, ALWAYS.

If you cannot afford the repair, then for your sake and others, get rid of the trailer.

Andy

I know what bearing creep is and I have seen evidence of it on different assemblies, either the outer ring creeping in the housing or an inner ring creeping on a shaft. I have successfully replaced bearings with sufficient interference (tight) fit where creep has occurred. But, I have never felt that a bearing should creep. If Jim's original bearing spun in the housing, it probably crept first.

I'm with Andy. The hub on a trailer is not a good place for a "this might work" repair. If it were on your tow vehicle, it would be different. You would know if it didn't hold long before the wheel came off or your windows fell out.
