Front Hubs Not Locking
Hello all,
As a new memeber, and P/S owner, I look forward to learning more about my F250 P/S, from many of you who know from experience. I have owned it for around 8mos. and really love it. It gives me the opportunity to enjoy my fav. sports, as well as it's really fun to drive even given the current diesel prices.
I had to replace a front hub assembly, recently. ( Bearings were toast, as a result of the previous owner not replacing the "O" ring. very important not to do that!)
I also installed new Warn Hubs as well, and all seems good, except that upon engaging 4WD, I hear the Diff engage, I lock in the hubs manually, but no action in the front wheels. I understand from the manual, that there is a "Hub pump" on the right fender behind the battery. Is there any way to tell if it is functioning? Any help would be fantastic. Thanks in advance.

If you installed new warn manual hubs the vacuum shouldn't matter either way. I would say something went a little sideways on the install or the transfer case gear selector motor is binding and not really engaging the TC.

Provided the hubs are installed correctly, you're left with the transfer case not engaging. This might be hard to do, but if you can get all 4 wheels off the ground, engage 4x4 and let the tires turn at idle. Check to see that the front driveshaft is turning. If it's turning, the transfer case is ok and it's further down the line.
Just to cover the basics, when you lock the hubs, you're sure that you are turning them to the lock position and not to unlock? I've never used Warn hubs, so I don't know if the two positions are easy to confuse or not.
