driveline vibes w/10" lift... HELP!
Those of you with lifted CC LB's what are you using for a rear driveshaft. I lifted my 2011 F350 dually CC LB 10 inches and no matter what I do I can not get rid of this driveline vibration. So far I've tried rotating the pinion up 5 degrees, a custom 1.5 inch transmission drop mount, completely rebuilding the driveshaft and of course shimming the the carrier bearing and nothing seems to help. After doing all that I looked into getting a one piece drive shaft made but no local driveline shop will build me a one piece that long. Some of the guys over on the cummins forum with similiar issues seem be getting away with a one piece without any issues. I am completely at my wits end with this issue. Anyone here have any ideas?
