Havent found any norwegian forums thats dedicated to daihatsu so im taking a shot here

My mother has a 2006 daihatsu sirion 4x4 (one of the first the came to norway with the nice side skirts etc etc )
and it sounds like one of the back wheel bearings is about to go to ****

Is it alot of work to change this? anyone got any tips or some sort of repair manual?

Hope my english wasnt all that bad
