    Whine in the rear of the vehicle

    Had wife drive home while I put my ear to the floorboard. Sounds like universal joint or a bearing in the rear diff. Sent from my SM-G950U using Tapatalk

    Whine in the rear of the vehicle

    No codes. I checked ABS feedback after the bearing swap and was functioning normally. Everything wheel speed related is internally sealed in the bearing. Sent from my SM-G950U using Tapatalk

    Whine in the rear of the vehicle

    2005 Expedition 2wd 180k all stock. Tires are good to new, recent rear brakes. Within the last week I've developed a whine that is speed dependent. Its definitely right rear more outboard than in. I always check bearing play, especially when I did the brakes a few weeks ago. I checked for...

    Water in #8 - Misfire

    Well, I have an update on a year old post. It happened again, this time on #7. Manifold is bone dry and it hadn't rained in a couple of weeks. We went on a 200 mile trip on Saturday with no issues at all, I even had the Torque app up and watching for misfires, etc. as this is the wife's...

    Trying to get rid of P0442 - small Evap Leak

    Evap works off a purge valve and pressure sensor. You cant bypass without throwing codes. You need a good bidirectional scanner to monitor and actuate the valves manually. Or smoke the system and hope the leak is visible. Basically the ecu sees that the tank pressure is changing without a...

    2006 expedition no crank/start ARRRGGGG!

    Under the dash, around the battery, along the firewall. I'd wonder if theres an issue with the radio receiver at the ignition switch. Do you have a different key you could try? Sent from my SM-G950U using Tapatalk

    Ignition coil connector part number?

    I'd suggest cutting some off a junkyard truck or van. Find solid ones that arent weak. Get extras to practice with. Depin yours and repin a good connector. Sent from my SM-G950U using Tapatalk

    Flashing check engine light?

    Just to be clear. Cylinder numbering on a Ford is unique. Front to back on passenger side on the V8 is 1-4. Front to back on driver side is 5-8. I've seen you mention removing the ECU etc. to get to the back 2 cylinders. That is to access cylinders 3 & 4. #8 is next to the firewall on...

    Flashing check engine light?

    There is such a thing as cheap knockoffs on the plugs. I bought a set of 8 from Amazon and they were all junk, the packaging was correct. I bought 8 good ones from the local AZ. Sent from my SM-G950U using Tapatalk

    Flashing check engine light?

    What about the COP pigtail connectors? Did any of the tabs break off and now are not securely held onto the coils? If you can disconnect them with the slightest tug without depressing the tab, this can cause a misfire as well. If you find a broken tab, whatever you do, DO NOT ever cut and...

    Flashing check engine light?

    If you've been dealing with the slight misfire for a while, you could have a vacuum leak somewhere. Extra air entering the system that is not monitored is viewed as excess oxygen in the system and the ecu will compensate by adjusting fuel trims. Fuel trims in these trucks are key to...

    TIFU O2 Sensor Stripped...

    Vice grips and a hammer to shock it. If you planned to replace it, cut the long end off with a hacksaw or cutoff wheel. Use the yellow map gas and get it cherry red, lock the vice grips on and smack it with a hammer. Sent from my SM-G950U using Tapatalk

    Spark plug threads damaged?

    It's possible you pushed some in or it fell in. I'd suggest pulling the plug again, though #4 is a pain. Get a brass brush, I bought a cheap set at Harbor Freight. If you're worried about dropping the brush, turn the engine over so the cylinder is at TDC. Use a drill and some brake clean and...

    Spark plug threads damaged?

    The two rear cylinders have a tendency to collect grit into the plug wells. Did you blow the dirt out before pulling the original plug? Sent from my SM-G950U using Tapatalk

    Fuel delivery system identification

    The control module has a nasty habit of galvanic corrosion between the aluminum housing and steel frame. In salty climates they are doomed. Updated units gap the module away from the frame. Sent from my SM-G950U using Tapatalk

    There is a large bracket that mounts to the pumpkin of the rear diff to attach it to the vehicle. Those are known to fail. Sent from my SM-G950U using Tapatalk
