    I'm going to be hitting the junkyards within the next month or so to look for a 14 bolt SF with 4.11's to swap out for my 10 bolt with 3.42's. What do I need to look for in terms of wear so I know I get a good axle and not a piece of junk one?

    Junk yard axles are hit or miss. Most of the things to look for are internal and a complete disassembly of the axle is required to see if they are any good. External, look to see if the axle is bent or if the spring perches are at two different angles. Check for cracks. Pull the filler plug and see if water comes gushing out or the oil is burnt. One other thing, see if someone put sawdust or oatmeal in the gear lube. This has been done to silence a noisy one and get it past the potential car buyer. If you can pull the axles, see if they are scored where the bearings ride or the splines have excess wear. Look at the condition of the ring gear and the pinion for any abnormal wear indications. Other than that, you'll have to tear down the carrier to look for any problems with the bearings.

    Like wheels said hit or miss. Most better junkyards will know milage of vhehicle parts came from. Maybe better off to find lowest price and rebuild. Or check local auto trader or trading post for someone parting out a truck. I have gotten some good deals that way. If you have room a whole truck could alsobe bought than sold for parts. Usally you can get your money back. We bought a 67 chev pick up with a 327/350 horse vet motor that was rebuilt for 500. Took out motor and trans and sold truck for 500. Deals can be found just look.

    Get for gear pattern wear and bearing slop.... Also stand back and see if you can tell if it is bent...

    I do have a 14SF with 4.10s, but it is an 8 lug, if ou are interested. For your info, Moser will fill and drill 8 lug axles to make the 6 lug for $50/pair..
