Alt; take a deep breath, pour yourself a soothing beverage and calmly think this through...I'm not being sarcastic!
Seriously, if it's not the bearings then you're on the verge of throwing some real money at a problem that is basically a no-win situation.
You didn't mention how much you currently have invested in this particular router, but I'm guessing that you're at least going to double or triple your cost at this point. You'll still have a used router that likely isn't worth any more than you originally paid for it, but even if you could find a buyer after you repair it, you'll still be in the hole.
If you take the same cash and put it into a NEW router, you'll have a machine that's perfect, under warranty, and that has readily available parts should you need them.
You already know that Sears (Craftsman) is belly up here in Canada, so anything you need will likely have to come out of the US, assuming it's even available...shouldn't be any duty, but you may get stuck for brokerage fees and shipping is another aspect; assuming you want to actually use it in the near future, the parts situation may have you bogged down for an indeterminate amount of time. Personally speaking, that'd make me nutz (more so than normal)!
You might be able to find someone who needs the non-damaged parts from your machine and will be willing to take it off your hands...no need to just throw it into the scrap pile.
You might even be able to recover your original cost; the person looking for a newish switch or whatever is sort of in the same boat as you!
Good luck and I hope you'll give some thought to Stick's VoE and well reasoned argument for a NEW machine.
In the spirit of full disclosure, I've been burnt every time I've gotten involved with used machinery, and I do mean every time. To me they're toxic.
