Have you noticed any difference is gas mileage when driving with the hubs locked? In the winter I usually keep them locked all the time. My last tank with them locked was exactly the same as the 2 tanks before that weren't locked. A bigger issue on gas mileage has been the colder weather.

Yup, Mine goes down in the winter .. Locked them in last week... Going to be a long winter...LOL..

I just replaced my old hubs, and I had to run with the old ones locked for a while. I was averaging 21-22 mpg with them locked. I do notice a difference since I replaced them,and not driving with them locked, but only 1 or 2 mpgs.

when its that cold outside the computer tells the injector to stay open longer, and squirt more fuel, hence the mileage drop. thats how a lot of those cheap performance chips work. they trick your comp. into thinking its -30 outside and in turn it dumps more fuel. more fuel=more power

Nice try, but not true. When the ice is off the roads, it's still the same temperature, and my mileage comes right back up to 25, as soon as I unlock the hubs. We get a lot of bad road conditions for a day or two (usually), then the roads are cleared off - even though the temps stay in the same range. I only lock in the hubs when it's really necessary (usually not more than 15 or 20 days through the whole winter season), and the hubs are just like a "lower MPG" switch.

its more draw on the engine. nwhen yoou lock the hubs the engine has to turn 4 wheels instead of just 2.

Absolutely - even if you're not in 4WD, when the hubs are locked you're turning the front axles, the front diff, and the front drive-shaft (what the English call the prop shaft for some reason).
