vibration in center of car both front cv axels replaced as well as front drive

✔️

have not done rear u joint was going to do drive shaft support bearing next anyway. how ever read about possible transmission cooler lines being clogged could cause same issue have you heard of this.

No I haven't .. IF cooler lines were clogged, should show up in transmission operation... Suspect major culprit is rear u-joint.. May not have play in the joint but is locked up or frozen.. After shaft is removed, rock u-joint back and forth 'both ways'... Should move freely!

ty will keep in touch to let all know how it goes

✔️ .. Cool .. That will be helpful to others with same vehicle/problem as well.
