I need help please ! I have a ford f150 4.6 Symptoms are the following ....

Look under the rear of your expedition directly in the center of your spare tire there will be a wing nut that is what holds the spare tire on you may need to spry some lube of some sort on befor you try and remove it as they spend years under the car in the elements and dirt hope this helps

The traction control system DOES cut your engine power when the tires spin. That is by design. The system cuts engine power to stop the wheels spinning and restores power once the wheels regain traction. It feels odd when the tires spin and power cuts out. It's good practice to lift off the accelerator when the system kicks in. Otherwise, if you are on gravel or slick streets the tires may spin, stop when traction control kicks in, and then spin again when power is restored. It is not an "elegant" solution but it does work for the most part.

No, even a 4x4 will have only 1 wheel that will spin on each axle in this instance. It's called a floating differential. For stock vehicles with non locking differentials like you have, both cannot spin or have full power at the same time. Hard to explain on this, but picture your car making a hard right turn. Both front wheels would be spinning at different speeds because of the turn. The passenger side tire is spinning much slower than the drivers side tire, therefore if both were spinning at the same time, your tires would chirp and skip on the pavement which would eventually ruin your differential. In offroad applications, we WANT the differentials locked and turning at the same time with true 4x4. But in normal everyday vehicles, even standard stock 4x4's, only 1 tire will do the spinning per axle unless it has possitraction or full locked axle. Clear as snow?

it sounds like your tires are spinning when you accelerate quickly.Check the condition of your tires. check air pressure. It should be on the door or in your owners manuel, if this is not the problem check tire size with owners manuel. if none of the above is your problem look for a set of new tires made from a softer rubber with more gripping power if this was at all helpful please leave me good feedback.

There is a fuel pump module electrical piece associated with powering up the pump. Most generally they are located on the frame just behind spare tire. when looking from the rear of the vehicle. Sometimes these corrode and cause the symptoms to be the same as bad fuel pump. Hope this helps.

The car is designed not to spin it's wheels when taking off. If you want to make it do that you need to either change the powertrain programming or replace some powertrain parts.

When on soft dirt or gravel, engage the 4wd. From a stop position, accelerate quickly to spin the tires. Inspect your starting position for spin marks. There should be marks in the dirt or gravel on opposite sides from front to rear. The rear may have two marks depending on limited slip or posi rear end.

either brakes are seized or the wheel bearing is seized. most likely the brakes are what seizes up. just jackup, and take tire off to check it out. it maybe a stuck brake, rust or dirt, or maybe a broken spring or two. good- day ! but first reach in back of tire and pull on the e-brake cable a few times at the problem wheel, it may be binding.

1. bad tire
2. bad rotor
3. bad axle

check tire first . not cv boot it just a cover for the axle - hold grease - dont let dirt in axle nuckles.under cv boot is the axle joint if boot is torn it lets grease out an dirt in an drys the joint out causing problems....

• At most times your over drive wont come on under 30 mph. check your tire perisher or your tired depth you mit need to get new tires tri a snow tire with stud es
