Shoot, one teenage burnout 50 years ago could put a diff on the die list decades later.
As far as 7.25’s go, I did multiple 100 yard burnouts for 5 years behind a 318 and then 1 or 2 years with a bit over stock 5.9 Magnum and the 7.25 never blew up.
(Yea I felt pretty lucky)
same here, i've done miles of one wheel peels in clapped out 318 cars with 7.25's and never had a problem. but those were all with like 195/70-14's that were hard as rocks.
same situation knocked on a set of 215/60's and scattered the thing goosing it on a RH turn.
lost an axle on another at speed while on the freeway. was a crazy lo-miles grandma grocery getter that never saw a lick of abuse.
but precisely to your note, nobody knows the full history. some innocuous event decades ago could've started it on the path that intersects with you JDA on a nice sunny day and the thing having a spontaneous disassembly event.
i said in another thread, these parts were never intended to last this long. they were basic transportation pieces designed to work within a specific set of parameters and we've long since exceeded that. roll on a 7.25 like you roll dice man, at your own risk.
