Clunk When Not On Throttle

[ledoff]

some basic info 2011fg xr6t, it has a stage 2 nizpro zf with tune

recently I have noticed that when the gearbox changes it to a higher gear when it isn't under load, it makes a clunk sound, I don't think it is coming from the gb itself.

am I right in think it could be a mount as it only happens when there isn't any torque on the box or drive line?

any ideas?

is it actually the diff bush, it is an upgraded one but it is old. I know the diff bush joke thing so is it actually? lol

Even a broken clock is right twice a day.

Being a ZF I would look at the gearbox coupling as well

zf was rebuilt about 8 weeks ago by nizpro, so I assume its not the coupling. I will invest in a diff bush any way.

Didnt you say previously that it had a build tailshaft ? and ZF tune ?

My built shaft and true trac is a bit more brutal also.

[Mrs Jeturbo]

have u got a zf tune in it? coz that happens with them sometimes it gets too brutal for itself

where you charged for a replacement coupling?

please stop quoting the post directly before yours

-no doesn't have built rear end.

-not sure if I got charged ill have a look at the receipt when I get home.

whats a reputable workshop in sydney that I could take it to to get the gb coupling and or diff bush done?
