Drive line vibration?
Hey folks,
First off, thanks for alll the help. Bought a 95 superduty PSD 4x4 with 200k on it a couple months ago. Its turned into a big project, but with the help of the list, I have completely rebuilt the front end, replaced hubs with manual Warns, all new tires, replaced all glow plugs, and have ordered new seats with the old ones too far gone to repair. In relatives terms, on to the light stuff.
I noticed a vibration in the drive line when I first got the truck and thought it might go away with all the repairs, but it's still there. The guys who just repaired/welded the 4" lift and did the front end alignment pointed it out, too. Its a medium vibration that starts up when you pull out at about 6 - 10 mph and goes away by 15 - 20 mph. Then it's smooth. Feels like its somewhere from mid-point of drive shaft to rear diff.
Any ideas?
Thanks again for all the help.

When the lift was installed was the carrier bearing in the driveshaft shimmed down?
If it has a carrier bearing and it was not shimmed I would start there....otherwise, I would look into replacing the driveshaft u-joints.
