Couldn't find that model on Sears look up. You are referring to a support bearing for the front auger shaft- correct? If it is a 1 piece housing, most times you have to remove the driven pulley etc and bring everything out the front. If you are real lucky, you may be able to remove both auger bearing retainers, any box supports and twist them in. In either case, look real hard at the impeller bearing for looseness. They tend to be a high wear item.
