take the break drum off pop the wheel stud cover loosen the nut and take off the drum inside,
On the inside you will see a dust cover and under the dust cover is a spring cir clip pull both holes together it will pop out hopefully use wd40 to help it .
Take out the sping clip and then turn the drum over and push out the baring if its stuck use a some wd40 and if still stuck use a puller (expensive bit of kit ) or you can heat the outside of the drum hub and then pop the barings out you can use a large spare socket to give you some coverage to hamer the barings out from the outside they can only come out one way so it should be eay to do. if all else failes you will have to get a puller or you could take it too a garage they may just opull the bearings out for you with any luck
