[6pack] Vibration felt in seat

[im sloane]

Hi guys,I've developed a pretty bad vibration, felt in driver's seat. I
believe that usually indicates a bad u-joint on prop shaft. I put it on jacks
last night, and noticed both back tires have so much play (in-out at top) I
first thought the lug nuts may be loose, but they were not. Is it time for the
rear-hubs to be rebuilt? I didn't measure the play, but they click back and
forth loudly.
thanks,Sloane :o)69-Six
