 Subject: Drive Line Vibration
IP: Logged
Message:
Test drove my used 2004 Dakota Sport w/24K and rough off road tires & didn't detect the drive line vibration at 40 to 45 mph. With a new set of tires vibration was severe. Dealer replaced D.L. with new factory D.L.-better, but not eliminated. I had D.L. balanced-no improvement. Rotating d.l. on pinion flange changes the severity of vibration but does not eliminate it. After 5 or 6 trips to the dealer they are trying to tell me that a little vibration at 40 to 45 mph is natural. Has anyone had any experience with this problem? Below 38 and above 45 mph it is smooth & quiet but at 42 rumble in cab is very annoying.

Just used a Dial Indicator to check for run-out. Found that just in front of hanger bearing, on the short shaft.o18 run-out. Is this enough to cause my problem? Vibration seems concentrated on bearing crossmember.

I know that it depends on how big it is, but for me 18 thousandths worth of runout is pretty bad. What kind of truck do you have. I might have a spare DL.
Finally... a V8. '01 Dodge Dakota RC, 4.7, 5-speed, 3.92 LSD. = R/T Killer.
well at least a stock one

If you need an abreviation for drive shaft, maybe you guys should try something like DS ? Drive line means much more. Did you try rebalancing the tires ? Is it possible that the knobbier tires were masking the vibration ? Since you said it was severe, I'd assume no, so maybe you should concentrate more on the tires that were changed, rather than suspecting something else.
Lead, follow, or get out of the way
