difference in axles for single and dual rear wheels?

difference in axles for single and dual rear wheels?

Answer:

Trucks that come with dually wheels usually have a stronger axle to carry the extra weight which trucks that need dually wheels carry, but fundamentally there is no difference in the axle itself. It is just a different wheel. You can buy dually wheels for any truck you can fit them on, even if it didn't have dually wheels standard.

yes there are differences. Most of the other repliers are dead on as to what the differences are. F150's get a softer suspension as well as semi-floating axles. Semi-floating axles means that the weight of the vehicle sits directly on the axleshaft. Overall the engines available are not different. Current models the F150 gets the 4.2L V6, 4.6L 5.4L V8's Older trucks (80's/90's) was the 300I6 302, 351W. While the F250/350 get the 5.4LV8, 6.8L V10 and Diesel V8's Older (80's/90's) F250/350s were available with the 300I6, 351W, 460 and V8 diesel. F250/350 get stiffer suspension rates and Full-Floater axles, a Full Floater axle is an axle where the weight is placed directly onto the housing itself and the axleshaft has no weight on it all it does is turn. The tires between 2 differ as well. ALL F-series get LT tires but the Load ratings are different. F-150's get a C-load range 250/350 get a D or an E load range tire. All this means is that the sidewall of the tire has more layers to it to help support a higher load. This also creates a stiffer ride since the sidewalls can't flex as much. The transmissions are all the same but the 250/350 will have an external transmission fluid cooling unit to help keep the fluid cool under heavy use. Hope that helped

Yes? You must have a reason for asking this but I cannot think what it might be.
