The bearing on my motor is squealing like crazy. Was wondering how much of a task is it to replace? Dealer won't be able to get out till next week some time. I stripped the stove down, cleaned, wire brushed, scraped. Cleaned out the fines. Tried to to spray the bearing with someWD-40 and it worked for about 5 minutes, and she's back to squealing. Any help would be great. Thanks.
