It may be only on square-backed SUVs, that body style creates a low pressure area around the back of the vehicle while driving, that can cause exhaust to be pulled n through the cabin vents under the body at the rear. Leaving the climate control in the fresh air mode causes the cabin to be...

Agreed, if you have 4 Auto then that's the way to go if you don't understand the function and purpose of 4 wheel drive. (And many people don't from my years of experience in the automotive business):rolleyes:

Going over 100K miles on original plugs on a naturally aspirated engine is fairly common, but because of the extra heat generated in the Ecoboost engines, they tend to erode the electrodes away quicker and increase the gap quicker. Then the coils can't fire the extra gap under boost conditions...

I'm sure that's exactly what it's about. Keeping HVAC on fresh air keeps cabin slightly pressurized so exhaust isn't drawn in around back of vehicle. The problem is worse with square backed vehicles, which most SUVs are. And in today's litigious world, having exhaust odor in the cabin is...

Only use 4H if you need it, that is if you are in mud, snow, or sand where your rear wheels are losing traction. DON'T use it of pavement or on hard dirt or gravel roads. You will bind up your driveline and cause premature failure of some pretty expensive parts. If you have the Advanced 4...

Wow, 110K for plugs??? Were those the originals? That's amazing for a 3.5L! Must lead a pretty easy life? I've seen them need plugs as early as 35 to 40K if they are used to tow. Anyway, I love mine. 0 problems in 45K miles and average of 19.4 MPG over those miles, which include about 3K...

Thank you for the information. I have been hoping that would be the case. If any significant number of order holders took them up on the offer that would relieve the pressure on the constrained commodities. I'm not changing my BL, Sas, MIC, LUX, Tow Package order. I've waited this long...

Intake carbon was a problem with DI only EcoBoosts. The later dual fuel engines haven’t had the problem. I remember in 2011 when the F-150 had the first 3.5L EcoBoost, a majority of fellow Ford employees had the same fear of what it would do to F-150 sales when these all-aluminum...

Well that and the fact the 500 was butt ugly. I think the 96 catfish design was the beginning of the end. Thank you Jack Nassar!!

The 2.7L was first available in 2015 F-150. There are some around with over 100K miles, it's all in the maintenance!

If the booster vacuum line is the concern, you’ll still have brakes, they just won’t be power. But you’ve been out of it for six months?!?!?! Most booster vacuum lines are just reinforced rubber hose.

The brake system bursting a brake hose Isn’t likely. Wonder if it had any electrical accessories?

The noise sounds like something related to angularity of the front CV joints. Lifts really increase the angle the front joints run at and they are just not designed to do it. And it is true that dealers can't change things to allow for tire size and gear ratio changes any more, the EPA...

If you did a 3" spacer and didn't do anything to lower the front differential there is a good chance the vibration is coming from the inner plunge joints on the half shafts. A 3" lift will increase the angle of the half shafts quite a bit and the inner joints aren't true CV joints so they will...

At least according to the Workshop Manual it's 106 lb.in. The owner's manual says 13 to 17 LB.FT. That's close to twice as much. Just snug them until they feel right! :rolleyes:

The torque spec for those bolts is 106 lb.in.

I agree, engines running under load are more efficient than engines under light load, that's why everything is geared so tall these days. This partly due to less pumping loss against manifold vacuum, and also due to higher charge density in the cylinder on the compression stroke. That higher...

I retired several years ago after 35 years with Ford in a technical field job. I took a part time job as shop foreman at a dealership after I retired, so I’ve seen all of this from both sides of fence. I can say that recalls are a fact of life for all manufacturers, there are so many safety...

In that case, the dealer has 2 business days after the drop to notify carrier of damage or missing components (floor mats, radio antennas, etc.). Looking at the close-up of your seat, it does look like a material/workmanship problem. I can't see how the concern down inside the seam could be...

That might be your dealer’s policy, but it’s not Ford’s. Dings, scratches, scuffs, etc. are damage. Warranty covers only defects in materials and workmanship. When a car is unloaded at the dealership they are responsible to find any damage (except for a few exceptions considered hidden...
