'06 Tacoma 4x4 front wheel bearing issue

hey everybody--I have a bad driver side front wheel bearing that Toyota will not warranty because they said the truck has been in a wreck(heavy front collision). Toyota found out about the wreck--no big deal--but the body shop took the truck in because I was having isues with the truck wandering at speed and I had a vibration. The body shop replaced the right front suspension but this is on the left----what is the possibility of that bearing being chipped or damaged in a wreck???
Toyota is denying the claim because I do my own normal services and the body shop denied doing any service work(but had the repair under my name) so Toyota is saying that because I refused their suggestions for repairs they are declining warranty! Any ideas and has anyone out there have a newer Yota that has been crunched in the front?
