Well here it is. My 04 LE Pathy has 274K+ miles and I'm not quite ready to put "Nicky" out to pasture. I noticed since my last 700+ mile road trip it has started to have a rough rumble like vibration when my speed is at 50 mph. In addition whie driving at normal residential speed, all is good. I was wondering if it's my bearings and races in the front end or is it in the rear portion. I would appreciate any help, inside knowledge, or suggestions on this problem. Thanks in advance.
