Here is the problem, my driveshaft(front end) vibrates horribly. I have TG long splines and it was professionally built by six states. The vibrating is only really bad when the hubs are locked in AND the t case is in 4wd. For example, if I have the hubs locked in and the t case is in 2wd(driveline still spinning), the vibration is very small. Or vise versa, the hubs are unlocked and the t case is in 4wd. Can anyone help me out??

 

Sounds like bad pinion angle.

The angle at the pinion is better than the one at the t case. It has single joints on each end, but I have heard of people running them like that without issues.

 

Trail-gear flat out states "This product is a heavy duty replacement part and is not recommended for use on the street."

when I had my driveshaft built by http://drivelinetech.com/home.php Brian said that the T-G shafts could not be balanced properly..

 

Ya, I know, but I feel it in 1st gear in low, thats rediculous

 

Do you KNOW it is the driveshaft?

Im pretty positive, but the thing is is that it only vibrates bad when the hubs and t case is locked in, this kinda makes me think it could be front end slop? I also have a v6 diff in the front, i dont know if that messes things up? Opinions??
