Okay... Big little problem. When coasting at about 15ish and below, I can feel a little shimmy from under the truck, and when I'm barely on the throttle I can feel it until I hit 15. Never did it before the tcase swap. I know a lot of fluid drained out of the trans when I did the swap, so could it just be that I'm low on fluid? Also, when I remounted the main shaft to the back of the case, the mounting did not fit flat against the mount on the case, and I had to force the bolts to go and push the plate down. I'm thinking that it got bent from somewhere. Came off fine....dunno what happened after. ???? Hoping that it's just because I'm low on fluid, and not in need of a new driveshaft because it was a bitch.
