Set of air bags was all it needed.

 

I would have overloaded it even worse then. My axle was starting to creak with or without a load in it. You said yourself you've never even driven one before, so you know NOTHING about the F150. You're just mimicking others like a Mynah Bird. (A Hill Mynah) Well, I'm off to a jobsite to see how my guys are doing...All 3 of them...My company is VERY new...lol

 

Methinks you were hearing something else, either that or you had a bad wheel bearing

 

Perhaps on his, but on mine they found one the leafs actually had a crack in it. I guess they said it traced back to a problem the truck originally had when I bought it new in '04, it something to do with the alignment on the rear end... forget the details. But apparently it was an issue the first of the production F150's of that "new" model. It was all done under warranty, I traded that truck in with 2,000 miles left on the warranty.

 

The key word there is "opinion" though. YOU may not like that the truck drove differently loaded than it did unloaded and had to turn some rpm's, but the fact is that it won't hurt the engine at all. Or does Johnny need to bring out his testing procedures post again? I wouldn't hesitate to pull 12-13k lbs with my 5.4, much less a v10.

 

That makes more sense then. The problem wasn't that it was an f150 and couldn't handle the weight, it was that there was a pre-existing problem in how it was put together.

 

I have no doubt the V10 can pull the 16k lbs it was rated for. I'm just saying where I was driving it wasn't all about the RPM's. I knew the mpg would be bad, but 6 was kind of depressing. Also I had some issues with the way the tranny jumped around between 3rd and 4th. Overall the truck did it, no problem, nothing even got warmer than normal on 5-7% inclines for 6 miles. The truck was capable, no doubt, just I would rather do it with something a little more powerful.

Before the V10, I had a 7.3, and before that a 7.4L (or 454 for those of us from those days). If you really want to hear an engine, put that 454 with a 3 speed tranny and climb some hills. It was kind of fun though, you usually had a race between the falling gas needle and the rising temperature gauge, which one would stop you first... I usually hoped for the temperature gauge, because then I wouldn't have to walk to the gas station until the next hill. Compared to that 454, the V10 was just purring.

Personally I would be much happier with a small direct injected turbo gas engine. Slap a couple of turbos and direct injection on a small V8 and I would be more than happy. You'll certainly get more mpg and more power at lower RPM's for towing.

But, I was surprised to hear the engineer for the 6.2 state that the 4.30 gear set would give you worse mpg because of higher RPM's which will cause more rotational inertia and more friction hence lower mpg. Of course we know the higher gears will give lower mpg because of higher RPM's, but I've never heard it directly attributed to those factors. That's why I would like to see a smaller engine with turbos. Smaller engine means less mass to turn inside the engine and lower friction for better mpg. Combine that with good torque for towing, you have the potential to have a very efficient gas engine for towing.

 

Try to teach US Ford to make small engine.
The 5 liter engine I did have in 2001 Mercedes SUV was pumping 345 HP with good torque. Still delivering close to 20 mpg on highway driving. That is 10 years technology.
Than I could never find the answer why I could drive Ford Focus with 1.9l cdi engine 10 years ago in France, but still can't have it here?

 

Thats in your truck. The same year F550 V10 could tow 33,000. With no changes it will be rated for much more in the F650 and F750.

 

Do they really put V10 in F650 and higher?
WHAT A WASTE.

 

Yes, starting this year. From 99-2010 it was F250-F550 and now its going to be F450-F750. How is it a waste?

 

Now I get it. They have leftover V10 that are hard to dispose, so they put them in rare trucks that are not having too many EPA restrictions. Couple more years and they will start putting them into boats, to replace the carburated engines they still install...
Have you Bill ever drove a boat that burned 55 gallons tank of gas in 2 hr?

 

They are still making new V10s, these are not left overs.

 

WHAT A WASTE

 

It wasn't that long ago medium duty trucks had gasoline engines in them that produced far less hp/tq than the 6.8l does. The place I worked for has ALL of their medium duty box trucks with gasoline engines in them. Reason was they didn't want the diesel fumes and smell making it into the plant. Just because you can't forsee a demand does not mean there is not one.
