2003 S-10 LS. 4.3Lvortec. zq8 suspension
I'm getting a bad vibration from somewhere in the driveline. I originally thought it was the drive shaft so I had the stock shaft balanced a few times and it never seemed to help. I've added the JTR shim package and changed the rear diff pinion angle and that still didn't help. I replaced the double cardan shaft with a new non double cardan shaft and it still didn't help
I decided to pull both the axle shafts out and measure the runout to see of they are bent. I'm getting .015" of runout on one shaft and .030" on the other. Is there an acceptable amount of runout on these shafts? If so, what is it? When I spin the shafts on the test fixture I can visually see the runout in the center of the shaft. The shaft is being rolled on the machined ends and measured with a test indicator on a non-machined section in the center of the shaft.
Would .030" be enough to cause vibration? I'm so sick of dealing with the driveline in this truck. It's been going on for years now. There were a few times when I was doing a burnout and the back end would hop really bad. The vibrations started happening after that.
