There is a part in the quadra trac transfer case called a viscous(spelling may be off) coupler that when working properly allows the front and rear wheels to spin at different speeds such as in hard turns. When this goes bad the wheels cant disengage so a tire has to kind of jerk and "hop" to keep up or slow down for the wheel moving at a different speed. To replace this coupler the transfer case has to be taken almost all the way apart (best done out of the vehicle) and a new coupler installed. The other option is to find a whole new transfer case. Either way, even doing it yourself isn't real cheap and i think a shop would charge quite a bit. There are other transfer cases that don't have this but unless you really really know what your doing i would not recommend a different model case.
If it is actually "chattering" like you say it may not be the transfer case. I'd check wheel bearings, ball joints, and the CV or U joints (whichever yours has) on the axle shafts (not the drive shaft). To check the bearings and ball joints jack up the on the axle and try and move the tire back and forth in the opposite directions that the wheel turns...so push in on the top and pull out on the bottom and back and forth. There should be absolutely no play here...even a little "chunk - chunk" back and form means something is worn out and needs to be replaced. In CV and U joints you should be able to see the play in them if you try and rotate the tire back and forth (again with the wheel off the ground). There is a little movement from the differential in the axle but there shouldn't be any in the axle joints. Hope this helps.

Yes, that can happen. When it does, the transfer case will need replaced. Causes include mileage wear and running with low fluid.
Overload can cause contact chatter. Once the contact closes, the voltage in the circuit collapses and that causes the relay to drop out. At this pint the relay energizes, since the voltage is back. This cycle will continue on.
Send it to a professional gun smith.
Part time is only for use on slippery road surfaces. It causes binding in the axles and transfer case if used on dry pavement.Part time is only for use on slippery road surfaces. It causes binding in the axles and transfer case if used on dry pavement.
convection causes the heat transfer.

Relay chatter in general is either from low voltage to the coil, may be a result of bad connection. or forein matter between the coil and the metal that is attracted to it. In cars relays are sealed so I would look at the voltage
