I have a vibration in my 96 K2500. I shipped it back to the mainland, picked it up in Dallas and took off for Delaware. After about 100 mile it started to vibrate slightly at first then got worse, it happens around 65 to 75 mph. I took it in to tire shop got all 4 tires balanced they said 1 tire had no weight at all which is odd for 33x12.50x16.5's and one was way off. Said it could of threw some weights. Started down the road still shakes some but not as bad. So once I get to Delaware I take it in again and have it looked at. Shop says that the pitman arm has some slop in it but everything else looks good. So I replace the arm and go back to get alignment looked at again. Once again everything looks good they say. But it still vibrates. So I put the rear up on jackstands and run it up to 80 mph, and it has a slight vibration from the rear drive shaft. But not what I was feeling going down the road. I plan on getting the rear driveshaft balanced, but can you guys give me any more advice? I don't want to shake the whole way back to Louisiana.
