You can usually get them rebuilt for less than 500 bucks. I wouldnt pay more than 150 at a junk yard.

 

Pull it yourself from something that is rolled or hit from the side. A bad front or rear hit that bends the frame or moves the axles can push the driveshafts into the transfer case which causes damage if the UJs do not break.

A quick test is to put it into 4x4 and turn the rear output. The front output should turn at the same time. This is pretty easy to do, at least on the 208s. Then tip the thing every which way and listen for any banging or loose stuff that would indicate a broken chain.
