Vibrations

[TTT]

R32 GTST with stock box and diff from what I can tell.

once I get to 40km/h, there is a vibration that starts that can be felt through the whole car.

it gets a little louder by 50km/h, kind of dissapears by 60-70 but is there as a loud hum..

By 100 and above, it is just a loud hum (similar to wheel bearing noise but doesn't change when you load up the left or right with bends in the road etc.)

It does it in gear and out of gear so I've ruled out anything frmo the gearbox forward.

How can I identify wether it is the shaft or diff or whatever else is between the back of the gearbox and the diff?

do you have a one piece tailshaft at all?

my brothers r33 has a one piece tailshaft and it vibrates like that, at highway speed you can actually feel the rearview mirror vibrating,

Flogged out unis can cause similar issues which then leads to a flogged out centre bearing

Also I would be getting this balanced again mine never did this if it runs true it shouldn't vibrate at all

it was another great job done by a shit workshop,

would it cost much to balance? does it need removed from car or how do they do it?

I don't know how many pieces the tail shaft is..

whatever the stock R32 GTST one is I suppose.

So more than likely not diff then?

Anyone want to point me in the direction of a Brisbane tailshaft related workshop? lol

ummm not the one that did SilverS2's brothers original job obviously.

Balancing shouldn cost that much .

And yes it does need to be taken of the car to do so

They put it on a lathe and spin at x amount of Revs

And will spot weld weight where it needs it to balance it

Providing it has been built correctly and all the unis are on correctly

Take it to driveline specialist at springwood there may even be one at archer field ?

Any one that specialises in drivelines etc should be able to do a decent job
