Strange Vibrations (In the truck)

[MMeilicke]

I am getting a virbration sound under the following condition: engage the clutch in 2nd gear, start moving without using the acceraltor, vibration noise starts. Continue accelerating and vibration stops. I have checked the exhaust system and it appears to be tight.



Any ideas?



Thanks

Mick

Upps. I forgot to say the truck is a 2004. 5 with a six speed transmission 44,000 miles.

Sorry about that.

u joints ?

or maybe you're just lugging the engine (below 1000 rpm) so it will vibrate a little.

carrier bearing

Check your carrier bearing. Mine is about to go and with only 21,000 on it. 2005 CTD NV5600 LWB QC 4X4

how do you check this?



I have some wierd rattles, and it is going to the dealer on Monday.



They don't seem to "find" stuff unless I tell them where to look

Thanks for the lugging thought. But it does not vibrate in reverse gear. Weird

I think I may have found the solution to the vibrations. TSB 03-003-04 talks about drive line shutter with the cure being adjusting the angle of the u joints. Does anyone have any experience with this?

Thanks

Mine vibrated the same as that, just moments before one of the u-joints on the rear shaft locked up. I thought at first carrier bearing, especially when I jacked the rear up and moved the tires. You could see the joint at the carrier bearing wobbling off center, but when I removed the shaft, the bearing was ok. Replaced all three U-Joints and put in a spacer under the carrier bearing, and no more vibes. This happened at 76k, so it seems I got more miles out of them than most others.
