Aqui fica um DIY a explicar como mudar os rolamentos traseiros em casa, está em inglês mas dá para compreender bem visto que as imagens falam por si
Apesar de ser de um puma, acredito que para alguns fiestas seja igual ou semelhante

"New bearing kit (one side of two) came with hubnuts but didnt use them as the ford OEM ones are reusable and are waffer type.
So hubnut off drum off and outer bearing race removed
Drum flipped over to reveal abs tone wheel, seal and inner bearing race
Next up abs tone wheel prised off, this was a bit of a pain actually
Seal and inner bearing race removed
Tapping out the inner bearing collar
Removed
Outer collar removed
Used the old collars to tap the new ones in place to limit any damage
New collars in place
Inner bearing race inserted and greased up
New seal tapped into place
ABS tone wheel cleaned and tapped into place
Outer bearing inserted and greased
Stub axle greased
More grease lightening
Waffer hub nut cleaned up a bit
Tightened to 235nm torque
Repeat for the other side!"
