Certainly on a Land-Rover FWH are hugely over-rated!

 

The swivel pins in the front axle rely upon the front halfshafts turning in order to keep them splash lubricated. If you disengage the FW hubs this lubrication doesn't take place, and unless you run periodically with them engaged you will wear out the swivel pins quite quickly. The cost (and hassle) of rebuilding the steering outweighs the very, very small saving in fuel.

 

Also, when you need 4WD you have to remember to get out and engage the hubs first.

 

Having said that, FWH tend to polarise opinions, and for everyone like me who thinks they are a complete waste of space there will be someone who thinks they are the greatest invention of all time!

 

They won't make a significant difference to fuel consumption.

 

Running with them engaged while in 2WD won't do any harm at all. However running with them disengaged in 4WD is bad news since you are very likely indeed to break something in the rear drivetrain.
