Front Vibration

[jdross440]

Has anyone solved the front end vibration caused either by the differential or driveshaft or both?
On my 2007.5 it had minimal vibration. I had the gears changed front and rear to 4.10. The installers had installed a defective pinion bearing and thought the driveshaft was out of balance. It vibrated so bad the whole truck shook. They had it balanced twice and then figured it was in their installation. They replaced the bearings and the vibration went down but was still worse than originally. It starts at about 58 and mostly goes away about 65. Then comes back worse around 78. I have had the driveshaft balanced twice dynamically. Each time it seemed worse. Each time they just added weights instead of taking off the previous ones. After the last balance I decided to remove all but the original factory weights. This put it back where it is now. I got so tired of it I have removed the driveshaft (no vibration with it out) and put it on a shelf until I can figure it out or get rid of truck. I don't want to put in the free spin kits.

I'm assuming you went from 3.73's to 4.10's, that will obviously increase the RPM of the driveshaft and would aggravate any existing imbalance issues. That said, there's no reason you should have the vibration.

I've had lots of problems with local driveshaft shops and their attempts at "balancing". I tried two different shops and had it balanced three different times. I finally sent the driveshaft off to Tom Woods, they basically said the shaft was garbage and built a new one. Came back smooth as can be. They've done three of them for me in different vehicles, they do a great job.
