Noob with auto/manual lock question

[hpcbmw]

I just bought a 2000 f250 with 4x4 and 7.3. The prior owner said the auto locking hubs don't work, so he turned them manually (hubs have a "lock" and "auto" position). The left side works fine, the right side is very hard to turn, and shows signs of using pliers to turn.

Two questions: 1. is there anything bad about using manual locking when i need 4wd.
2. I've read about the different ways to fix the auto lock (tracing vacuum, guzzle's website, etc). I'd like to keep auto lock feature, but it seems there are LOTS of parts that go bad. It seems easier to just replace the hubs with aftermarket manual lockers. I was told Warn manual locking hubs are only about $100 pair. Should I just replace with the Warn units?

Thanks for any info.

If you want to keep the auto feature then follow guzzles guide. It works well but you just have to maintain them. Alot of people just go to the Warns. Right now if your turning them manually you arent hurting anything. The previous owner probably didnt have them cleaned and greased.

TAke that snap ring out, remove that section and clean and grease all moving parts. right before you pop that cover back on, squirt a little oil in there to keep the grease wet. Keep the ford locking hubs.

I've never had good luck with the auto hubs. Warns are $185ish for the standard ones. Premiums will run you about $225.

I mean the ford hubs are manual if the auto fails. Just keep them clean and greased. Why spend money you don't have to>??????
