You are welcome.
I would hate for anyone to go through the nightmare of waiting for months then having to call and pay another 40.00 to get a replacement for a "lifetime warrantee".
They are either too busy with the few people they have working, or figure the problem will go away if they don't answer.
It will cost you a mininum of 15.00 plus postage to send it to them.
If you e-mail customer service, they may send you a axle with wheels for no charge. They have been known to do that.

I see that Bachmann deletes messages that don't praise their customer support.

Where is the message I posted here last night, Bachman, concerning poor warrantee and customer service on the 4-8-4 Northern and J-Class 4-8-4???

Not sure how you guys got off the J-Class subject, but the person with the loose driver wheel is not going to get any help from repair unless he wants to fork out 15.00 plus another 40 for the newer J-Class.
Fix your old J-Class loco if the loose wheel is all that is wrong with it.
Some of the new J-Class aren't as good as the older ones.  They run and track terrible.  You definitely need wide radius curves to keep them on the track.

As you can guess, I am disgusted with Bachmann and their customer service.
