08 QX56 drive vibration
New member and first post... I have a 08 2wd QX56 with 130k miles. Recently started having issue with vibration while in drive (D) around 2k rpms and above. Shifts through all of the gears smoothly up until that RPM range in Drive (D).
I can drive in (4) and do not get the same vibration and can also move to Neutral (N) and coast without the vibration.
U joints seem fine from a visual stand point.
Thoughts or ideas before I drop off at dealer?
Currently no codes and no Trans flush to date that I have record of.
