Ok, I am cleaning out my garage and I have spare birfs and spare hubs, plus a spare long side front axle. How hard is it to seperate and change a birf in the field? My thinking is, if I dont seperate the long side axle from the birf and I brake that side I can just change out the whole axle. BUT! Then storing is is rougher because of the additional length and with two girls and a dog space is at a premium. So are they easy enough to change in the field? Or am I overthinking this?
