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.

Up date . Replaced torque converter and Shift solenoid pack. About 50% of the vibration is gone. Did add oil to transfer case. So I'm thinking that's going to be where the last of the vibration is coming from. Man talk about a job. Been awhile sense I pulled a transmission out. All those electrical plug ins . Had to keep wiggling the valve body to drop but it came out. solenoid was easy. The hang up was exhaust bolt. Clip with a nut. Try to get them off all they did was spin. But I got it done wife's happy to get her Jeep back.
