2003 F350 DRW 6.0 Shakes violently above 45MPH
Hello all. Been lurking the board for sometime now and just recently picked up a 2003 F350 Crew Cab Dually with the 6.0. This is my second PSD (my first being a '99 F350 CC dually with the 7.3).
When I test drove this vehicle, the currently owner warned me that it "shakes". My 7.3 had the death wobble, so I automatically thought that is what he was referring to, after my short test drive, in which I only took the vehicle to about 45, I ponied up the cash.
After *attempting* to bring the vehicle home,all went well untill I hit approximately 47MPH. The minor vibration became a horrible, eyeball rattling (literally the numbers on the instrument cluster were unreadable), death box. Tires look fine, though the steering wheel seems to be a bit out of alignment.
Shaking gets increasingly worse with speed (undriveable past 55)
Any ideas where to start looking, and what specifically to look for on this truck?
Thanks in advance!
again the truck is a 2003 F350 Dually Crew Cab, 150K Miles, 6.0PSD, Auto. No CEL lit.
