I have a vibration at 70 MPH which blurs the traffic I see in the rear-view mirror. Under 70 MPH seems to be fine, but not perfect.

• When I remove the front driveshaft the vibration goes away completely up to 104MPH - smooth as silk.
• I had the front driveshaft rebuilt; when I re-installed it the vibration came back.
• I've had the front shaft balanced a total of 4 times: 3 times by the shaft rebuilder, then I got frustrated and had it balanced again by another major and reputable shop. Vibration persists.

I also have some minor radial slop in the front output of the T-case. I don't know if this is the cause of the problem or if the slop exacerbates a marginally balanced shaft.

Therefore I need to look at another truck to determine if the slop in the T-case front output is normal or excessive.

Could someone in Colorado in the Denver/Golden/Lakewood area with a 2003-2005 Ram 2500 4x4, QC, LB please contact me (PM or post) so I can look at your truck. All I need to do is grab the front T-case output and check radial play; additionally I would need to know if the truck has any vibrations at speed.

Can someone please help?

Thanks in advance,
Eric
