hey guys, got a issue with the running of my car atm.
its still driveable but when i hit 40km or above the car vibrates really badly. it seems either the box or tailshaft is vibrating against the chassis.
prior to this, i had a gearbox change & it was running fine before.
what would it be this time round?
me & my mechanic have double checked everything and it all seems to be fine. mount is in good condition & tailshaft bolted up correctly.
(previous box was a Rb20 & the box i have now is a Rb30 if it matters)
any input appreciated. Cheers
