Wierd Vib
Hey everyone sorry I have not been around I have been quite busy between work (working for that promotion lol) and the GF, I usually to go to Alachua on my days off to see her.... 160 miles north of St. Pete.
Ok I finally decided to do the auto to manual swap. It only took about 3 days but thats was also waiting on parts. My question is I have a strange vib at 55ish and then agian at about 70. Its a pulsing vib almost like a heartbeat?? My friend told me to flip my drive-shaft 180 degrees cause I didnt mark it when I took it off. Any ideas?? I still need the console cover plate I am waitng one to come into the junkyard.. Everything else is fine I have had it done for about 2 months now I have driven it to Alachua already thats how I found the vib. It got 24 MPG ... Sorry I know thats not great but better than the 16 my truck gets...
My New Truck as of 12-31-07
I have done a level kit and 315-75-16 BFG all Terrains. Oh and the 5% tint.

If the driveshaft wasnt balanced correctly for the distance between trans and dif, then it would cause a vibration. Now, keep in mind, the vibration from a driveshaft should be rpm based. So it should vibrate at the same rpm on most every gear. If you had said it was just 50mph then I would say it was tire balance not the driveshaft. Is the vibration in the whole car or is it in the wheel/seat?
