I put the edge evolution with the cts monitor on my truck and ever since then and even before that i have been having alot of problems with universal joints on the rear shaft. i seem to break them easily but i just put a new set in and i have an uncontrollable shaking in my mirrors and cant figure out what the problem is. i had originally thought that it may have been the u-joints but now i have no clue. can anyone help me i dont want to get stranded on the side of the road again. if anyone can help any advice would be very helpful. thanks
Nick

Nick I had that problem on a LIFTED CHEVY BLAZER, It's your drive shaft, either buy one from the junk yard or have the one you have cut

 

the u joints where probably put in out of phase and now they are causing your driveline to vibrate... either have a show look at the driveline (off the vehicle) to make sure its turns true and is balanced or make sure the u joints are in right...
