shimmy shimmy shake shake
 

ok, so at a speed of 50mph, i am getting a vibration from the trans/transfer area. it goes away at about 55.. then if I am being stupid, it reappears at around 70 and once again goes away at about 75(not too worried about this one as I really do not drive that fast). Any thoughts????

What have you checked so far, what do you think it might be, have you had your front drive shaft rebuilt or replaced, how often to you lube your u-joints, what about your roto-flex, have you checked to see if it is cracking and how about your tire, did you loose w weight.
That being said, don't make us guess, until after you have had all these things checked. If it is the front drive shaft, "QUIT" driving it before it fails and punches a hole in your tranny.

Mike Sorry,not trying to make you guess. As stated in my signature the drive shaft is new, or newish replaced about 12k ago along with the transmission as a result of the shaft failure. I have checked and lubed all with exception of the rotoflex. I will do so on Saturday when I go to the shop to do a few other things. As to what do I think it might be... I honestly do not know.The shimmy is very subtle I doubt anyone in the passenger seat would notice. If I were to just guess I would have to say that it feels as if there is something out of balance. I know vague. but I really cannot think of anything else that would be making this happen.
