    My rear end is still vibrating after i got the drive shaft rebalanced the tires balance and rotated. It starts around 65 m.p.h but it will quit after about 15 minutes. I aint got no idea so everyone up for suggestions. /forums/images/graemlins/k5.gif /forums/images/graemlins/angryfire.gif

    What tires? If they are bias ply tires they can run rough until they warm up. Sounds similar to your problem.

    Mine does the same, goes away after a bit. I have 35x14.5x15 TSLs.

    Make sure your drive shaft operating angle is not too excessive. No matter how well your drive shaft is balanced, if the U-Joints are at too much of an angle, then your drive shaft will vibrate. Spicer recommends no more than 3 degrees of angle.
