Well, MN, if it were mine (and I don't know if this is correct to do this....), I would take some electrician's black tape, and neatly put a couple of cascading wraps (start at one end, overlap a bit on the previous wrap, and so on) around the rubber strain relief. Be sure to wrap tightly and neatly.
Next, I would look at what may be causing the cracking. If the strain relief areas are being bent while they are being stored, they would show some cracks. If they are being stored in a very warm area, that might cause the cracks. Maybe a lot of temperature changes?
I'm actually puzzled by the cracking, because I store my portable tools in the plastic cases they came in, and sometimes the strain relief's are bent so I can put fit the cords in the case. None of mine are cracked. I have a 30+ year old Craftsman 3/8" drill that isn't cracked. I hope you figure out what is causing the cracking and please share with us.
Hope this helps
