2006 Tacoma PreRunner-Vibration

Hopefully, someone can offer some insight!! I have had this vibration/groan going on for about 18 months, only happens at 65mph-75mph and then stops. I have had it in to Toyota, spent quite a bit of money looking for the cause, had the front driver side wheel bearing replaced, was assured that was the problem, nope that didn't work. Now taking in for the newest warranty notification for the Propeller Shaft Universal Joints for a drivetrain vibration/noise. When I scheduled the appt. they weren't very encouraging that this was the problem. Basically the response I got, we will check out the U Joint(s) which is the only part covered under the warranty notification.

 

Have you balanced your tires?

 

my first bad vibration was a U-Joint, I replaced that then it was fine but always had a front end vibration when I hit 55-70. I replaced my stock shocks with stock off road shocks that I got and that when away. Not sure what the problem was old shocks seemed fine but it fixed it!!!
