axel removal question

ok, i needed to remove the front diff on my 13 500ho. i looked at a bunch of videos on this as i do with just about anything i do, every one of them showed them removing the hubs, tre, lower ball joint, caliper, ect… to get the axles out. why? i have had mine apart several times and all i do is remove the lower arm bolts to the frame (i have struts not upper arms) then remove the axle nut and move the whole assembly forward while sliding the axle out. easy. i don’t get why they go through all this trouble. is there something i’m missing?
