I checked the U-joints and everything appears to be in good shape. Got the front end alignment as I planned, but the vibes are still there. She vibes when accelerating (and just slightly when I level off) so I am almost sure it's coming from the drive train, not the steering components.

Will these vibes cause any damage if I keep driving it right now? I am not planning on leaving it be, I want my Jeep to last and I want to do what I can right now to try and eliminate them, if they're gonna destroy something. But I do have to drive her 30+ miles to work every day, so leaving her parked until I figure this out is really not an option.

Do you think there's a good chance the 1" MML would get rid of it, or should I just save some $$ and do the SYE/CV conversion ASAP?
