I own a 2002 7.3 auto ex cab long bed F250 w 50000 miles.
My truck has a vibration during acceleration from about 1 mph to 10 mph. Its had the vibration since new. I never took it to the dealership because I put an 8 in lift and 38s on it a little after I bought. Now ive dropped it back down for mpg.
Running the lift and never greasing the splines on the oringinal drive shaft had the splines worn out badly and causing a lot of vibrations at speed. I ordered up a new custom drive shaft, still two piece and installed it last weekend. The truck still has the same vibration.
I read on another site that there was a tsb put out in 2005 for superdutys that have a problem that sound similar to mine but it dosent state the solution to the problem.
If anybody has any ideas to try to get closer to finding the problem or knows the solution i really appreciate the help.
