Offset between shock and mag - major problems

The offset between my 15 inch mag and shock on a TATA indica bounce 2007 model is incorrect - even after replacing the rear axle bushes the shock was still touching the tyre on the side (rear drivers side - passenger side no problems) when there was weight in the car. We added spaces (not that thick about 6mm) so that the shock does not touch the tyre but now in a matter of 4 months I have replaced the wheel bearings about 5 times - I have to go and replace them again now. The wheel bearing seems to get damaged easier once I wash my car - strange enough
