The tools are what allows the retrofit to be possible. If you have a single row IMSB you might get it out with some improvised puller. If its a dual row, you most certainly will not. Until I invented the current tools the dual row bearing wasn't being extracted because other pullers were not up to the job and would either break, or blow a hole through the case. Its imperative that the bearing be extracted via a means that exerts force on the IMS and not on the crankcase, or shares the load between the case and the IMS, like my most recent development, The Faultless tool.

If the person doing this job doesn't have the proper tools, my feelings are the same as JFP.
