Only during acceleration? Same speed coasting along is fine? Look at the trans mount and u-joints in the drive shaft first, because they're both cheap and you can just look at them to see that they're bad.

Make sure your hubs are unlocking. I was wheeling the other day, shifted out of 4wd then hit the highway. I noticed a shake at about 50. Then I looked down and realized my posi knob was still out. Slowed down, unlocked it.... The shake went away. Also check if anything is on or wrapped up in your drive shaft.

I only feel it on accel. Coasting is fine. Im going to replace the rear ds u-joint. It wiggles a little when in a certain position. Hopefuly this will solve the problem

Spicer is a good name, and I prefer the grease-able ones. Do yourself a favor and replace both at the same time for the piece of mind.
