i'm working on a gmc chevy envoy (2002) the front drive axle bearing is broken, is this a hard job? i went up under the truck and the inside of the axle moves up and down in the case about 3 inches! is the axle part of the engine crank case? it looks likethe axle is in the engine. is there something else in the case i need to worry about? i hate to take this apart and find out the job is a little more than i expected.
