Estimated repair cost for rear axle repair or replacement

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. Roy
