2008 Postal Jeep Wrangler X Vibration
Wife uses the Jeep everyday. Already replaced front universals . New Filter and Royal Purple in Transmission. Vibration hits around 25 and again 45 mph. But not all the time. Drift at 25 mph or 45 Mph with trans in N . No Vibration it stops. Thinking Transfer Case , Converter lock up, or Shift Solenoid pack. Anyone with this same problem please help. Jeep Has 100000 miles on it. Serviced by me personally with all Synthetic Oils. Checked what I could put my hands on. No play in drive shafts.
