Which model? You could be referring to anything from the FL70, all the way up to the Coronado.
16,000 - 19,000 lbs., depending on specifics.
15,000 - 20,000 lbs for a regular line haul unit, depending on specifics of the vehicle.
Between 5,000 and 20,000 lbs (or more), depending on what exact model you're referring to. A 2005 Freightliner could be anything from a Sprinter van up to a heavy haul tractor or vocational truck.
Number of variables here. It'll depend on the weight of the power unit (Freightliner makes several models), what type of trailer is being pulled, and whether you want loaded or empty weight. Empty, you can expect the weight to be anywhere from 27,000 lbs. and up, again dependent on the tare weight of the power unit and the type of trailer being pulled.
Depends on model, features, mileage/hours, etc.
Freightliner never made a model called the 650.
Freightliner never made a model called the W700.
Between 15,000 and 25,000 lbs. all things dependent.
Unless you have a 4x4 or 6x6 unit, there is no front differential.
Depends on what it is. Freightliner markets vehicles in truck classes 3 through 8.
What's the configuration? For a single axle straight truck, the allowed interstate gross weight is 33,000 lbs. For a tandem axle straight truck, it's 54,000 lbs. For a tractor-trailer, it's 80,000 lbs.
There isn't a fuse.. it all goes through the engine ECM.
