Hubs Squeaking

[fordmas]

I haven't used the 4wd in many months but the other day, I went out back to test something and put it in 4Hi and locked the hubs. Driving straight, I have no issues but when I turn, the hubs squeak loudly. If I leave the hubs locked but put it back to 2Hi, it goes away. I was thinking it was a wheel bearing but wanted some more expert opinions.

Take a look at the axle shaft u-joints. Pretty common issue if they're worn out.

the u-joints in the axle shafts are known to make noise while turning.

intentionally??

negative, that would indicate they're dry/failing. You might be able to spray some WD40 on them for confirmation.
