Cost for manual hubs...

Hi all,
I have been reading numerous post on the locking of hubs on 4wd's and was wondering how much it usually cost to replace the auto locking hubs?

The reason being I always here the clicking sound as if they are locked, when in 2hi. I have read and followed all the post of backing up to unlock them after shifting from 4hi and 4lo. One post stated it won't damage them even if the hubs were locked all the time. I would like the peace of mind of manually unlocking those guys.
Thanks! :p

Cool, thanks Carlton.

AC has them for $20 less.

I bought some warn premiums for my old bronco on carparts.com (are they still around?) and when I called to make sure sure it was the right part number they guy quoted me like $60 for the pair, compared to $120 on the web site...worth a shot to shop around.
