vibrating when under throttle

Asked by Jan 25, 2016 at 08:43 AM about the 2004 Ford F-250 Super Duty XLT 4WD Extended Cab SB

Question type: Maintenance & Repair

my 2004 f250 6.0l 4x4 is vibrating at 40 to 60 mph (new tires and wheel) and at 70 mph it starts growling. i cannot pinpoint noise. I feel it mostly in steering wheel but some in throttle. I fee it worse when under throttle when you let off it quits mostly. All suspension parts feel and look pretty good. I suspected tires till I replaced them and its exactly the same. thanks for any help you can offer.

You may have a u-joint going out, check the u-joints. Another area to check would to inspect the flex plate that the torque converter bolts to, check for cracks, and check the torque converter bolts.

Thank you, I never thought to check the flex plate.

It is hard to see the cracks if it is cracked. Looking for little black fine lines, but I'd check the u-joints first for play and it is best to take the driveshaft out to inspect the u-joints as you may not find play in them but you would notice that they do not move freely.

Your talking rear shaft correct. Since in 2 wheel Dr the front shaft don't turn. Am I correct on that?

Yes it would not turn. If the u-joints where frozen up in the front axles, you would notice it in the steering. The front driveshaft you would noticed when in 4x4.

Oh ok I see now. Your talking axle ujoints. I'm sorry. I had a blond moment.

So check the rear driveshaft u-joints.

Ok. Great. Thank you.

Could front brakes and rotors cause this as well or would that make a constant vibration?

If you had warped rotors, you would feel it when you break only. This is sounding more like front wheel bearings. Jack up the front and spin the wheels to see if you hear any noise. Pull back and forth on the wheel to check for play. Look for rust by the axle nut.

Ok thanks. I'll try that next.

Every thing looked and felt pretty tight. All ujoints looked good. I guess I'll just take it in somewhere and have it looked at. Thanks for your help.
