Ok I found two different sets for axles both dana 44 fronts with 8 lugs and 14b rears one says 4.10's and the other says 4.11's. Both would suit me. The ads say nothing about condition. Both listed as $500/set. My questions are, What should I look out for on these? Is this a fair price?(seems reasonable from what I have seen)., What should I ask about these?, If these need seals and bearings, how much would it be? Thanks.
