This is certainly something that has crossed my mind as well, the only thing is I have no idea what it would cost to change the rod bearings. As a purely preventative measure this seems like a fairly expensive thing to do.
Also, are there any risks involved, i.e. actually introducing new issues by doing the work poorly? Tolerances for the new bearings will supposedly not be as tight as for the original ones as you can only get "one size fits all" parts while the original bearings were applied according to actual measurements of the individual parts (or have I misunderstood this)? Can this cause issues?
Anyway, will be very interesting to get some insight into this
