Estimated repair cost for rear axle repair or replacement on 2004 Nissan Titan

Rear end has failed and needs replacement parts and labor to install and repair

Asked by for the 2004 Nissan Titan
need to know what parts need to be replaced.

Thanks I thought of that after i posted the question. Sorry I just got the bad news from the mechanic who is currently looking at my truck as we speak. He says he looked inside the housing and saw a mess.Whatever that means. I was looking for a general answer i guess of overall cost. Thank you
assuming the worse, a rebuilt carrier assembly is about 500
ring and pinion is about 300
all bearings, seals and crush collar is about 125.
labor is about 7-9 hours.
this is assuming the axles are good.
