slight vibration

I changed the pinion seal on my 2003 tj dana 30 and I now have a slight vibration. It almost feels like when a u-joint is bad. the u-joint is less than a year old.

Unbolt the driveshaft at the differential and reconnect it after rotating it 180. Also recheck the pinion nut is properly torqued.

Slight dimensional/weight variations and allowable tolerances... the driveshaft and yoke are closer to being balanced and true connected the way they are now versus the other way around. Good to hear you've got things fixed up for you now.
