Suzuki: greasing front hubs, suzuki sidekick, locking hubs

Question
Hi, in winter my 4x4 front locking hubs are just about impossible to turn and lock .  I asked the dealership about it, they said it'll be about 500.00 dollars to grease.  can I do it myself?  Is there a site that you know of which shows a video of how to do it?  By the way I have a '97 suzuki sidekick 1.8l 4x4

Answer
If you look at the hubs, there are fasteners on the outside "cover" that contains the portion you turn to lock and unlock.  Take them off and remove the cover.  you will see that there are additional fasteners where the main body fastens to the hub.  Remove them, and the body of the locking hubs.  Clean the hubs, inspect for moisture (water) which can freeze and make the hubs stiff to operate.  Then grease all the sliding/turning portions, but do not completely fill the hub with grease, and reassemble.(note: ask the auto parts guys for slightly thinner than normal grease - it IS available even though the parts guys may not know of it  using thinner grease will make the hubs easier to turn in extreme cold)
