Anyone with a gooseneck experiencing what feels like a lowend driveline vibration on start up?? I am wondering if the goose give the truck more rigidity and transmits more vibs thru the suspention.

 

Define lowend vibration. If you mean when you start off at low speed, it is a common problem. Mine has done it since new. I just replaced all the u-joints and the center hanger bearing and it has decreased a lot. Really, barely notice it at all now.

 

I haven't noticed any. But I am leaving on trip in a few hours so I will pay close attention.

 

Havent noticed any at all since new, in fact my truck is smoother with the trailer hooked, did just put new ujoints in but, didnt vibrate before or after
