Re: Finished lift kit, now have drive shaft vibration
Well vibration is a frequency thing. So it might get worse and better
at different speeds. Things that vibrate have an "eigen frequency" that
makes them vibrate/move pretty violant at certain frequencies.
Check the driveshaft for missing balancing weights. (or have a driveline
shop balance your driveshaft)
isn't the driveshaft hitting anything ?

Re: Finished lift kit, now have drive shaft vibration
You are correct, we already have a proper t-case with fixed yokes and
axle with the slip yoke on it so we don't need to butcher our t-cases.

Re: Finished lift kit, now have drive shaft vibration
Actually, now that I think about it, I need a new tranny mount. Perhaps
that, along with the Transfer Case Drop kit will do the job. I'll get it
done tonight and we'll see.

Your ujoints are not under the same load when decelerating.
Drop the transfer case and see what happens. If you don't want to change
ujoints now, at least buy two spares and keep them in your onboard toolbox.
