So I had my original driveshaft in and it caused a nasty vibe and also made that angry sparrows noise. So I took it out and swapped in one from a junkyard and 2 months later it started making the same noise. Go figure. So I'm gonna rebuild my original one. I looked up the parts and I can get a greasable CV joint and u joints or non greasable. I'm leaning towards the non greasable but still torn on which ones to get. All parts are spicer. Also, if that CV ball goes bad, can it cause vibration? Just want to be sure I don't have another problem with it. Thanks.

 

You can get vibration from bad u-joints, a bad centering ball/yoke,
or a sloppy, worn slip yoke.

If the slip yoke on your original is still good, you can rebuild it.
Non-greaseable Spicer should be fine, unless you plan to be in the
water a lot.

If you have a lifted 2000 with a low-pinion D30, that might
also be a source of vibration. You might consider a transfer
case drop to improve the pinion angle. Or swap in a good
high-pinion D30.

 

Took it all apart today. Slip joint feels tight no slop in it. Centering ball was very loose so I guess that was the source of my vibes. Gonna order up some parts tonight for it. My pinion angle isn't perfect but it isn't garbage. I got drop brackets and it helped now I just need some adj control arms to dial it in. If I could find a hp30 for cheap that was be best but I've had a hard time finding one
