4 wheel drive question (manually turning hubs)
#16
Yes, it would accomplish the same thing. However the OE plastic hubs are really cheap and prone to sticking. Have you ever taken one apart? The entire internals are plastic and pot metal. Really cheap. The Warn or Mile Marker units are very nice Stainless Steel and will last forever. They only cost about $150 for the set (link to eBay listing -> Mile Marker 449SS Locking Hubs Manual ChevyDodge/Ford : eBay Motors (item 390153461179 end time Feb-09-10 03:45:36 PST) When I did mine, I sold the OE units for more that the pair of the Mile Marker were.

For those not familiar with the ESOF system or part-time 4WD, please note that driving in 2WD with the hubs locked will cause increased drag and lower MGP. While OK for the duration of a snowstorm, ie a day or 2, not so good for the entire month/season/year.
Here's where the extra drag comes from (in 2WD, front hubs locked):
Front tires drive the axle shafts, causing the ring & pinion to spin, turning the front driveshaft. This causes extra wear on the inner spindle bearings, carrier bearings, pinion bearings, pinion seal, t-case input seal & bearing(s).

So, if I am understanding the Mile Marker hubs, you don't want to leave them locked all the time as well. OK. They simply eliminate having to rely on the vacuum to lock the hubs in, you get out and do it by hand whenever you want 4 wheel drive?
For the first time in a very long time, I took my Excursion out over this past weekend. We just had our second storm of 20+ inches of snow, sleet and ice. The first was a week before Christmas. It really didn't seem like I was in 4 wheel drive. It felt more like 3 wheel drive cutting in and out with 2 wheel drive. The transfer case was definitely providing power to the front axle though. I think I might have one hub locking in on the front, and one isn't. I need to get it into my mechanic soon.

There's the magic answer! Don't want to leave the hubs locked all the time, eh? Stock equipment or aftermarket! Right?

I couldn't turn the hubs to LOCK with my hands. Thought I needed new ones. The 24"+ snow that hit us made me think "I need to lock in the hubs." I took a red rag and draped it over the center ridge of the hub. Got a Big set of Channel locks and open up the jaws. Put one jaw on one side of the ridge and the other on the opposite side. with the jaws on the OPEN position it made the handles almost a V configuration. I DID NOT CLAMP DOWN ON THE RIDGE ,I placeDdthe jaws on their side. I turned them by the handles and whamo they broke loose, reversed the position and turned them back to AUTO. Did this a few times and now they are somewhat loose. What a difference with the hubs locked in. Now what do I use to keep them from not sticking. I did the lube recently but eliminated this part.

I'm interested in switching to the Mile Marker hubs that are listed on ebay. Can anyone tell me the difficulty involved in replacing the cheap plastic OEM ones with the Mile Marker ones?
My issue with the OEM's on my '00 X LTD 4X4 V10 is that I had to use a pair of vise grips to get them to move into position to switch to 4WD and applying all that force to one small section of the hub center strip is causing the plastic to crack. I attempted to switch back to 2WD by returning the hubs to the "free" position only to find my "4WD LOW" dash light is staying lit.
Does this mean that even if I switch to the Mile Marker hubs, I may still have an issue switching back and forth between 4WD and 2WD??
P.S. I'm in Southern Maryland (Lexington Park to be exact) and it's nice to see there's other X owners in my neck o' the woods with similar problems. Misery loves company!!

For your hub sticking issue. Yes, a great upgrade is to swap the POS OE units for some nice Mile Marker or Warn ones. The install is simple and if you do a Google search you will find lots of info on how to do it. Once done you can cap off your vacuum lines and never have to worry about leaks that could affect your HVAC system too.
