The tractor manufacturer may have the best say on front chains. With four wheel drive I don't understand why the front drive should be weaker???
1 word... steering. Rear axles are huge bars inside of pretty stout axle/transmission housings. All they need to do is spin.
Front axles have to spin & steer. That requires several gears lots more bearings, seals & other moving parts. The bearings are usually the weak spot that get crushed by heavy loads on the loader, which promptly cause seals, gears & other parts to fail. Also based on tire size, it's easy to figure out which axle they expect to get the most load & traction.
