Now that the cold has arrived in NY, the driveline vibration on the SDL is definitely more noticeable.

When cold, there is a moderate vibration in the driveline from 1700 to 2200 rpm and it lessens to a minimal vibration at 2600 rpm and above.

However, when fully warmed up, the vibration lessens to less than moderate.............almost minimal at 1700 to 2200 rpm and is almost unnoticeable at higher rpm's.

My questions to anyone who has experienced this:

1) Center bearing

2) Universal joint

3) both??


While I can certainly replace everything under there while I'm in the process...........any insight from folks who have changed one or the other would be appreciated.

I'm contemplating purchasing a rebuilt and balanced driveshaft and just exchange the entire deal..........unless someone has a better idea on isolating the issue.
