Vibration at 80km/h

[Lex]

New as in 2ndhand…. Will check and replace if necessary…. Vibration definitely feels rear and not central though…

Have look? You never know?

 

[Dr_Mutley]

Yeah definitely

Check driveshafts,CV's and wheel bearings..

Is it still there if you manually pull it back a gear? In my VE V6 4 speed auto the vibration goes away when I pull it back to 3rd gear at the same road speed.

The vibration goes away at different revs…. It only occurs under load at low revs, and around 80kmh…. Pulling it back into 3rd increases the revs and it goes away (as does accelerating)….

Check drive shaft centre bearing, wheel bearings or it could be rear drive shaft cv’s as previously posted

Thanks mate….
I put a new centre bearing in it already thinking that was the likely culprit…. Will assess the other rear spots as well

It is also possible the drive shaft is out of balance.

When the centre bearing went in, if the two halves were not aligned as they were before, vibrations are likely.

I seem to blame my torque converter in the auto, it has got to be something in front of the transmission because you haven't changed the ground speed.
