Please help guys. I've got very bad vibrations - Motor mounts look good (from what I can see). I've posted a message on the other forum - easier to read there rather than repost everything here. If anyone has any ideas, please either post here or on the other forum!

Thanks in advance

 

Check driveshaft. Probally u-joints.

 

Thanks, but I already checked the DS, and it looks good. Besides, could the DS even be the culprit if it shakes like this at idle, sitting in the driveway not rolling?

 

Ya mine did. When u checked the driveshaft did u just look at it or did you check the play of the u joint to. Look for cracks, and if u can take it off and move the u joint back and forth.

 

The U joint moved freely both ways - My brother had a bad DS, but his was fine when it was sitting still. My shakes do feel very similar to his when he was on the highway with bad U joints.

 

Another thing worth mentioning is that the diff mount had been "clunking" during hard launches prior to this. If the diff mount is destroyed could it cause this shaking even when sitting still?
