F150 4.6 2000
I just purchased a 2000 F-150 with the 4.6 l with the aode and 3.08 gears and have the same problem . my vibration is worst at 45-47 mph and again at 70-75 mph .
The dealer has so far balance the tires as if I didn't know the difference between tire vib and drivetrain vibration! Then they tried to tell me I had heavy duty tires (please the tires on my family sedan have a higher load rating !)I have seen several posts on this on this board so lets all keep each other informed if we find a resolution to this problem .

Hi,
My name is George. I have a '98 4.6l 3.08 rear end auto trans and just bought it. Right away I noticed a high pitched noise coming from the truck and it sounded like the rear end. Like yours my noise was coming at 35-45 and then again when I went over 70 mph. The Ford mechanic said the bearings in the rear end are being eaten away by the synthetic grease they put in them. He knew exactly what the problem was and said it would be a 5 hour job to replace 4 or 5 bearings in the rear end. One of the highest costs besides labor was the different synthetic fluid they would have put back in. I don't remember the name of it but I have written down somewhere. I haven't had the work done yet. The Ford mechanic claims he was doing about 3 rear ends a week and has had to work on some after only 20k miles. Mine has 51k.
This seems to be a wide spread problem that Ford is maybe trying to ignore. Maybe a class action suit would be appropriate here.

helminc.com is the source for factory manuals. There is nothing that compares with these but they are costly.

I posted my problem here a while back. My 2000, F150, 4.6, 20,000 mi, HAD and STILL has a drive train vibration in it. Mine happens between 50-60 mph. I took it in on January 2 and they kept it 7 SEVEN WEEKS and still can not fix it. They replaced the motor mounts, 3 different drive shafts, rear end housing, ring and pinion gears, cab mounting bolts and bushings, etc... It is still not fixed and they told me not to bring it back to them, they don't want to mess with it any more. I have called Ford, so far they are trying to call it a vehicle characteristic. I also put in a call to the Dispute Resolution Board, but no news yet. I don't want to be negative on Ford but I have started looking at a Chevy and a Toyota Tundra to replace this thing, tired of dealing with it.
Good Luck, hope yours works out better than mine. Ford has lost a future buyer.

I have a 98 and it has the high speed whine in the rear end. So far I haven't had it worked on. I did have a mechanic test drive it last week and lo and behold he said he wouldn't have anything but a Tundra. I too am considering something else since my 98 so far has a high speed whine, door jamb crack and misaligned leaf springs which could cause a fuel tank puncture.
