I just bought an 04 excursion with the 6.0 diesel. I took a trip to vegas and noticed a humming/ vibration about 55-65mph only in overdrive. i have checked u joints and they look good. The x does have a small lift its the bracket kit with stock springs. What gets me is, I don't notice it driving in town only in overdrive at highway speed.
View 8 RepliesI have an 04 f-150 supercrew 4x4 lariat with 103k miles that has a pretty bad vibration between 45-50 after it switches into overdrive, when you turn overdrive off the problem goes away. I've taken it to the dealer and they put shutter guard in it an said to let it work through for a couple hundred miles. It still hasn't gotten any better, what it is?
View 3 Replies2008 2wd 4.6L 98K miles F150 for the past few weeks has been humming with a rhythmic vibration which feels like it is coming from driver's side front wheel. It doesn't do it constantly, nor at all speeds. Once I hit about 25mph, you can start to hear a humming. At 35, slight vibration. Between 50-60, heavier vibration. Sometimes at 65+, it subsides quite a bit. Both front rotor assemblies are newer, and I put in a brand new left because I thought it was a bad bearing.
View 5 RepliesThis is on an 04 Excursion, 4x4, 6.0 SPD. I have started experiencing a vibration at highway speed, 60-70 mph. After 70 it smooths out a little but still noticeable. I've replaced both rear tires and still have the issue. When I put my foot on the accelerator I can feel it more but as soon as I let off it drops off dramatically. I am thinking u-joints, which will be replaced this evening...
View 4 RepliesI have an unmodified 2000 Excursion 7.3. with 239000 miles on it. My transmission started to slip in overdrive. I could turn off the OD and it would run fine. I was in upper Wisconsin headed home to Georgia and figured the cold had something to do with it. Drove sixty mile with OD off turned it back on shifted fine and drove 750 mile to Paducah, KY stopped to eat and it started down the road and it slipped again.
Drove 45 miles stopped added 8 oz of tranny fluid and it drove fine back to a friends house and after I dropped him off and headed home it started again. The tranny is serviced every year, new filter, drained torque converter. I use Amsoil Synthetic ATF. I have used the truck to tow a 10000lbs trailer over 65000 miles. I was not towing when this occurred. What is going on? I guess what I am asking is my tranny about to become toast or am I looking at something that can be fixed easily.
This might be a dumb question but the light for my overdrive is blinking and it won't stop. I tried pushing the button on the end of the shifter but it still blinks. No codes are triggered. This is on my 2000 7.3l 4x4 limited. I haven't check the fluid level yet. Just got home from an exhausting trip. Here is a picture.
With it on ....
With it off ....
I have a 2002 7.3 ltd X with the 4r100 transmission. The trans shifts fine until it get over 160 deg (glow shift gauge in test port) Then the OD stops working and get no engine braking until I turn off the OD. when od is turned off, appears to shift OK. When the trans temp gets below 150, I get the OD back. The OD light did flash on 2 occasions but no code while engine on and light flashing but OD was working at the time. after shutting off engine and restarting light stopped. New fluid and filter, torque convert was flushed also and X has larger 6.0 trans cooler. Tran did get hot once while towing 4 ton trailer 240 f, thus bigger cooler. what would cause the OD to go out when above 160 f but come back when cool?
View 7 RepliesMy X has started shuttering in overdrive this morning. I have taking it out of overdrive and seems to go away , maybe a slight notice.....
It did shutter one time at about 2000 rpm while power braking.... but cant get it to do that every time.... possible coil...???
I have 2005 ford excursion with 24300 miles. My speedometer is not working, engine light on , abs light one, overdrive flashing. I just changed speed sensor on rearend, but my speedometer still not working.
View 4 RepliesI have an '05 V10 with 74,000 miles. The overdrive button on the gear shift does not work and it keeps me in trailering mode. If I put it in park and jostle the shifter and steering wheel, sometimes it works. Also, the back-up sensors no longer work.
View 5 RepliesToday i go out and crank my truck and it fires right up. I notice the overdrive light on the shifter is flashing. It did that a few days ago but stopped within a minute or so. This time i noticed the check engine soon light was lit as well. I checked my scan gauge and it said three codes stored. The first one i looked at was P0705. The truck was running fine the whole time. I turned it off and tried to crank it again.
This time it just turned over and over but would not crank. I cleared the codes before checking the other two codes. I wish i would not have done that but I wasn't thinking straight. I tried several more times to crank but it never fired. One time it tried to but never fully did. I gave up and switched cars. I am going to try again when i get back home. What causing this?
So while driving to work I start experiencing some weird behavior with the transmission. It would shift hard and seem like it wasn't pulling hard at all. I looked down and saw the overdrive off light flashing. Got to work, turned the car off then started back up and the light was off. Any thoughts?
View 14 RepliesMy Ex just started making this humming noise between 45 - 55 MPH -- beyond 55 MPH and the noise is gone. The humming noise comes and goes about every second and disappear if I get off the gas. I'm having difficulty determining where the noise is coming from. Seems like is coming from the front end area or under the hood. Not really sure.
What could be causing this? For what its worth, my tires were recently rotated and balanced. No vibration on the steering wheel and truck drives straight.
So it sounds like a whine at low RPMs, but once I get going it goes away. Popped the hood while she was running and took the filter housing loose and you can hear it through the intake... It's all stock....
View 14 RepliesI have an 08 F250 supercab 5.4L that I bought this past July. The truck has 153000 miles on it now it had 150000 when I bought it. I don't drive it every day just usually on weekends and when I need the truck. The truck was really well maintained and had all the work done at a local ford garage. I live in western pa and lately it has been pretty cold and snowy so I have been using the 4x4 more than I normally would the past few days. My wife was driving the truck the day before yesterday and had it in 4x4.
The past 2 nights it has been really cold right around 0 degrees. I drove the truck yesterday and it just didn't seem right when I first drove it almost like there was a tire going flat or a flat spot with one of the tires. I got out and checked and everything seemed ok but it was still doing that. I saw that the passenger side hub was still locked while the drivers side was on auto and I was in 2 wheel drive. When I got home I sprayed the hubs down with PB Blaster and tapped on them with a rubber mallet. I put the truck back in 4x4 and drove it down my road to the end then put it back in 2 wheel drive and reversed down the road. When I got back into my driveway and checked the hubs were both in auto so all was good. T
he only thing now is when I am driving everything is normal but when I start to brake or decelerate I get a humming noise like you would get with off road tires on the highway. I wouldn't say that it is that loud but definitely noticeable and there is a vibration in the floor in the front along with the humming. When I am going really slow decelerating you can also hear a noise similar to if you would spin one of those wheels with the metal pegs at a carnival or something to win a prize.
I have a 1999 f-250 super duty 7.3 .... Recently my truck has started making a humming noise when push the throttle and I can feel a slight vibration, the noise and vibration go away when I let off the throttle, I have changed all five u joints, both wheel bearings in the front, the steady bearing, changed tranny and both diff oils, put new brakes and calipers all around and pulled apart the hubs but I can't seem to find what's causing it. What it could be or what I could check? It has an 8 inch lift and is sitting on 37's and some performance upgrades, could any of that cause this ?
View 9 RepliesThe front end on the ex started humming really bad today after driving 350 miles to Memphis Tennessee. When I noticed the humming I pulled over and unlocked the hubs thinking the front axle is low on gear oil. No change when back on the interstate. If I turn right at highway speeds the noise completely goes away. While driving straight its pretty loud. The more I turn left the louder it gets. Just had the front end apart to do all ball joints tie rod ends etc. the hubs looked great and didnt have any play at all. The noise happens between 40-65 mph. After 70 mph the noise goes away. Doesn't go away when I let of the pedal, hit the brakes, put in neutral while driving, or accelerate. Could it be the hubs?
View 14 RepliesI have a 2003 F150 manual 4WD with 4.6L engine and 165000 miles. When i am driving i feel a vibration in the steering wheel and on floor board that intensifies when i press the accelerator. I do hear an irregular humming that sounds like it is coming from the driver side front. I checked the wheel for any play but it was very tight. i check tie rod ends, ball joints no play. i recently changed both u-joints on the rear shaft and the bearing hub on the passenger side front. Also, the steering feels a little 'wobbly' when i make sharp turns. it almost feels like it is giving. What else should i check?

80% of the time the car drives perfectly smooth at all speeds. However, there are times when I'll hear a slight vibration type humming and a little (very little) vibration in the steering wheel. HOWEVER, when I touch the brakes it feels as though the rotor(s) have a major warp in them. It's so bad that I'm afraid to to slow the car with the breaks so I'll usually gear down to a lower speed first.
If I keep driving for another 5 or 10 minutes it will go away completely -- braking is as smooth a butter.
I'm getting a vibration through the floorboards when I take my foot off the gas at high speeds. It has a low-pitched (like a subwoofer) hum to it. It's amplified when I go over dips and the suspension compresses, but doesn't exist when the car is in neutral.

What is the solution to fix the secondary pump humming/vibration noise? I get this humming noise from my driver side center dash area and according to few other members, it's the secondary pump. Some dealer fixed it by moving it to the side a bit to stop the vibration.
My dealer told me that's false and it's normal to make that noise (never had this noise before) and if there is something wrong, VWoA will issue an TSB to fix it..
Well, they won't do anything until there is an TSB and I was wondering if it's a easy fix that i can do it myself??
