I’ve only noted the broken upper ball joints on the “cheap” kits that do not provide a revised steering knuckle that corrects the angle. Can’t say I’ve ever seen an axle issue (discussion pertains to the 1500 pickup) and I’m in the desert SW where all the cool kids gotta lift!
Shop that does all our service work( last 12 years) says he sees stripped mainly passenger side axle shafts on lifted Rams all the time. This one has a pro comp lift on it.
Probably stay away from buying lifted stuff in the future, but this truck is ultra sweet. Very sharp. Its sold, just waiting to get it back from service.
