Exercise your hubs

[gordonford]

Was showing a young lady the finer points of driving a 4X4. Went to show her how to manually lock the hubs on my 04 F-350 4X4 (or$X$). Ooops the center portion would not move. A squirt of WD-40 to free them up followed by moly lube to keep them free. Now on my semi annual service list. (Automatic hubs are exercised every time I put the truck in 4-High to go up our driveway (+20% slope))

Wow... you have a 20% + slope on your driveway. You must not have any building codes in your neck of the woods. I have a 7% slope on my driveway and the county inspector forced the builder to pave it for better traction before signing off on the occupancy certificate. Of course, the expense was out of builder's pocket because we had already signed the contract.

Good preventative maeasure for the hubs. I had mine replaced with 23,000 miles under warranty for the same reason.

My truck does not have ESOF, but I'm assuming that the hub operation is similar with the manual and auto/override hubs.

I have also noticed that they are a bear to turn if left too long. I now try to remember to turn them to lock and then back to unlock every time I wash my truck. I haven't had any problems since then.
