Hi all. I've got the above mentioned vehicle with the 7.3L psd, 6 spd, reg cab, 4X4. There's about 50,000kms on the odometer and it normally runs flawlessly. I've done almost nothing except oil changes to the vehicle.
Lately though it's developed a shimmy or vibration at 1500-2200 rpm. I get it in all gears and only when the clutch is engaged. I haven't tried it in
4wheel dr. yet as I don't use that in the summer. Does this sound like a u-joint in the driveshaft or possibly something else I haven't considered?
