IT"S GONE!!!!!!!!
I'm not sure what did it but today I did track bar bushings, sway bar bushings, all the tie rod ends and the stabilizer and had the tires balanced. And the brain shaking is gone! My only regret is that I did it all at once and wasn't able to test drive after each part to see what made the biggest improvment. But if it wasn't for you guys I wouldn't really have known where to start and probably would have spent alot more time and money before figuring it out. THANK YOU ALL!
On a side note, I took the truck out wheeling today after the repairs and besides a little shimmy from 55 to 60 on the road there, it worked killer. I've driven alot of full size trucks that would have had trouble climbing some of the stuff I climbed in it. These things will climb a tree, literaly. I feel like I may have stumbled onto the best keeped secret in the 4x4 world. These trucks rock and you all can now consider me an official fanatic of the Jeep Comanche.
I'm already looking to snatch up some more of these trucks at rock bottom prices for parts and spares.
Thanks again.
