Driveline vibration - ZF-6
This is my first post on here, though I have been browsing for months, and know that there is a wealth of information.
Picked up the truck in sig about 6 months ago, and have had an annoying vibration. Does not come through steering wheel but is instead a seat of the pants feeling. Comes and goes occasionally, but the shifter continues to vibrate back and forth as if the whole motor and trans is shaking. Manual 4x4 selector shakes as well. Tires balanced and aligned. Carrier bearing is tight.
These were my thoughts
1. Possible dual mass flywheel issue? Truck shakes a little at idle. (A little more than my brothers 7.3 ex)
2. Injector skip? 45* starts can be a little smokey, although I probably need glow plugs, the smoke continues for 1-2 minutes.
3. I plan on going through and doing all the rear ujoints and carrier bearing even though they seem fine, I'm at my wits end.
Any help would be much appreciated.
