Cast aluminum just does'nt work as well as a cast iron bearing housing. In high speed/load applications something can place the shafting out of balance and over time the bearing will begin to loosen it's seat. Although, this may take some time and/or never occur - but when it does, it's bearing + housing replacement. In cast iron, typically just new bearings. Using 6061 forged aluminum works better, but still is'nt cast iron/steel.
