Vibration in cold truck

I know there are several posts relating to driveline vibrations, but has anyone experienced a vibration around 50-60km/h (30-40mph) when their truck is cold? After I drive for 5-10 minutes it goes away. It is not a constant vibration but kind of pulsates or drones in and out every 15 seconds or so.

Brought it to the dealer and of course they didn't experience it. Just wondering if this could be driveline, diff or wheel bearing? My rig is a 2012 DC 4x4.

 

....and it is not the tires. I just switched them out for my winter set. Same thing. The truck does have a set of billies set at 1.75" in the front.

Any suggestions?

 

.....sounds almost like driving on a rumble strip.

 

same thing apened to me! that why I find your post! what is it! dealer did not heard that!

 

Try switching it to 4 hi as you're driving. If the vibration goes away you have a bad needle bearing in the driver side front diff. ECGS sells a replacement bushing that solves the problem.

 

Thanks, it stoped when at 4 hi, seem to be needle bearing! I am lifted 3", does non-lifted have this problem too?

 

Experiencing similar situation in my '13 TRD Sport DCLB. I have it lifted in the front about 2-1/2" with 5100/885's and LR UCA's. It happens only around the 40-60km/hr speed range. Goes away in 4WD Hi setting.

This. I have the same problem in my truck, it's on my to do list for the new year.

 

Thanks guys! I've been searching this issue, too. Same problem with my '13 TRDOR DCSB. Lifted 3" with 285's. I thought it was the tires and went away when they warmed up.

 

Just ordered the bushing and tools to remove/install. Hope this fixes it.

 

Mine does the same thing and I’ve already done the bushing swap. It took care of that vibration, but the other vibration is still there.
Edit,, mine did it before I lifted it.
