...and while I'm still here, I have sort of a clunking feeling when I accelerate from a stop, which to me would indicate a U-joint going, however when I take it in to the shop, they lift it up and grab a hold of the driveshaft, nothing... Is there something else, a more hidden U-joint??? (I only have 63k miles on a '94). Thanks again.

 

motor or trans mount. bearing in rearend or t-case.

 

Yeah the above or possibly a bad center driveshaft support/bearing as well
