(Its not the tires for sure). I went ahead and pulled the driveshaft assembly to check the u-joints and grease them. According to info I pulled up on various websites, this assembly is NOT in phase because the yoke ears are not in the same plane. Looks factory to me, what say you?

I am not sure what years were involved but there was a TSB to replace the two piece style with a one piece. This was to eliminate a low speed vibration or shudder on acceleration. It was for 2wd models only if I remember correctly.

Didn't find anything obviously wrong, so, I greased everything up and put it back in, and now the vibration is worse. Put everything back the way it was, didn't forget to tighten anything, the only difference is the fresh grease in the U-joints. At 35MPH, it now vibrates hard enough that the sun visors drop down a little. Ran out of light tonite. Going to check things again tomorrow. John The dream is dead, long live the dream.......😥

I think the problem is a tight joint and its right in front of your nose. Also double check the transmission mount. I don't know how you can say the shaft is out of phase as your picture clearly shows its in phase. 8414536-shaftinphase.JPG (49 downloads)

Based on pics like the one I attached, the drive shafts are NOT in phase. 8414647-drive.jpg (144 downloads) John The dream is dead, long live the dream.......😥

When you had the shaft out could you move the all the joints smoothly esp the front one?

When you had the shaft out could you move the all the joints smoothly esp the front one? Yes. That was part of the reason I did pull the whole assembly rather than grease it in place, I wanted to feel how smoothly the joints moved. All moved smoothly, none felt 'tight', none felt rough. They were all the same style aftermarket joint, so, I assume they were all changed at once, and not individually as they wore out. Before I pulled the joint free from the rear, I marked it to be sure to put it back the same way too. John The dream is dead, long live the dream.......😥

I had my mechanic look at it and thinks the same. There's no excessive slop anywhere, no obvious damage to either shaft. So, now I gotta pull the unit again and get it balanced.
