Warn premium hubs?

[onebad7.3]

My stock hubs are froze in the locked position, thinking of getting the warn premium hubs. My fuel millage has been down a little since the hubs locked in and won't unlock. With the hubs locked in, would this cause a noticeable drop in fuel millage?

Sure would as its turning you front axles the whole time.

You can pull those hubs out and take them apart soak them is some lube and get hem working agian. Go to guzzles page as he has step by step on how to rebuild them.

Other thing is once you get them to move make sure you keep doing it many times and they will loosen up. Then just keep them lubed and turn them on and off each time you fill up will help keep them from freezing.
