Makes me feel alot better about how my truck drives

 

For the guys with a low speed vibration I would suggest getting the rear wheels off the ground and have someone run it up and look under the truck to locate the vibration. Bent drive shaft, broken shock would be what I would look at next if a shop has already gone over it. Check the rims to see if any mud has acumulated on the back of the rims. If it has a rythmic pulse to it, look closely at the U joints. Good luck....
