when is this necessary and can it be checked?
what is the cost?
One of the first checks you should make is during disassemble. How do the old bearings look ( wear pattern )? Next you want to check the crank for straightness ( V-blocks). All ok, Put the crank back in with the bearings you are going to use. Spin freely, you are good to go. Replacing bolts with studs usually don't warrant a line hone. Replacing caps, always. IMO, line honing or boring is often dune unnecessarily. Save yourself some $ and check it.
