I have an 88 cherokee stock height, stock everything, and yesterday it started vibrating at 25-45 (my speedos off) at highway speed it goes away, but there seems to still be a subtly shake/clunking. Any idea what this could be? Drive shaft? U-joint? Bearing of some sort?

 

Ya could be u-joint in the drive shaft. And check the ones in the front as well

 

Its my roof mounted light bar...must be vibrating in the wind

 

Lol that's stupid. Zip tie time lol
