If you are going to be in HKG, I can give you directions to the luggage place. They will do ANYTHING to your luggage, including replacing your non-replaceable wheels with replaceable wheels, and they go do it in one day if you need them to. It is in South Kowloon fairly close to the waterfront/sidewalk of stars. They fix I think ALL the luggage for almost all the airlines in HKG...their place is crazy with mountains of luggage everywhere...
