Lately I have noticed that when I take off from a stop, my jeep seems to shudder a bit until it hits about 2000 or 3000 rpm. Kinda annoying. Any idea what this could be? It seems to transmit through the transfer case and through the shifter, causing the shifter to jump around a bit.
Shaking when taking off from a stop....

Check the motor mounts for cracking, and the tranfer case mount and torque mount. The torque mount is next to the transfer case mount and has the single bolt that runs all the way through the skid.

Rear driveshaft ujoints, but those will usually make noise before they get bad enough to cause vibes.

Hello lanejac,
I think Bounty__Hunter is, as always, right on target.
My Jeep developed that same S-H-U-D-D-E-R when moving off in first gear, but at no other time. The cause turned out to be a broken driver's side motor mount.
If you prop up the hood so you can watch the motor from the driver's seat as you release the clutch in first gear, you might be able to see the entire motor rotate toward the passenger side (torque reaction) if the motor mount is broken/defective.
A limited amount of engine roll is normal, but in case of my Jeep, the motor rotated much more than could possibly have been reasonable.
There are other possible causes of that start-off shudder, but I think the motor mounts, t-case mount, and torque reaction limiter are, as Bounty mentioned, a good place to start your investigation.
