Will a 5th gen axle fit on my 4th gen? I don't care about the performance upgrade and stuff. I just want to know if it's a direct component swap?


Details-
2006 v6 4runner with 180k miles. Rear end is shot. Shop is saying I pretty much need all the rear axle guts and seals. If they're new OEM cost is going to be more than my 4runner is worth. Finding a whole use axle with the shop to install is going to cost at minimum $3k. Which i can kinda confirm- on LKQ the whole rear end is just under $2k, so appox $1k in labor. I know that I can swap out a whole axle, but i'm not confident to swap out the guts myself.
So will a 5th gen axle fit on my 4th gen? I have a line on a local 5th gen that is being parted out with 59k miles for $400. There is someone else thats parting out a 4th gen but they haven't gotten back to me about it so i don't know if i can get it and at what cost.
