I have a 1994 S10 blazer with a 4.3 liter V6, a 5 speed manual, and four wheel drive. Just recently I drove it up north and used four wheel drive a little bit. Nothing crazy just a couple sandy spots where I started to spin. So shortly after it started vibrating pretty bad in first and second gear when its under a load. If im in second when I get to about 2500 rpms it starts to vibrate than if I keep accelerating it will eventually stop somwhere around 3500 rpms (im guessing). Im not sure where to start looking, im thinking possibly rear driveshaft u-joints, or could it possibly be the tranny? it does have 186,000 miles on it so pretty much everything is worn out.
Thanks
