Unhappy Bad Shake (Death Wobble) & stalling.

Hey everybody

New to the site about 3 month ago I bought me a very clean 95 7.3L just this past dive home about back she presented a problem. First off the first 200 miles back she had no problems then I noticed when I was accelerating to 75mph she started shaking real bad to the point it would rattle things around my cab like the drinks in my cup holder. I have read many questions and answers saying "might be the balence on your tires or allignment. The only thing is she would only do it from 70 to 75/76 and it would kinda go away at speeds about that. My first guess would be the carrier bearing. Anyone have that problem and did you solve it?

Second question is there are times when I step on the brake and let of to roll forward a little then restep on the brake she wants to stall and it feels like the engine and tranny want to over power the brakes then she stalls out. I replace the front break pads about 2 weeks ago and thats when she started with that problem. My guess on that would be the sensor that tells the tranny to go into neutral when the brake is pressed is causing the problem or the problem is inside my tranny or the tranny it self. The truck had 213--- miles on it when I bought it it may be time for a new tranny or tranny rebuild. Any suggestion on that would be greatly appreciated. Im new to diesel and this is the newest truck I bought. Any comments or advice it welcome, she it my daily driver and my truck that takes me home for leave.

my guess is the TQC isnt unlocking like it should. and iwould chekc tire balance like you stated. it could be a few other things, but shaking at certain speeds is an indicator of tire balance. could be other things, like your tranny, etc. but start with tires.
