Mechanical Click - S3 Live Axle

[kingsea99]

Hi all

I have a live axle (ital) xflow that has developed a mechanical click when the drivetrain is put under load when the clutch is let out in gear - most noticeably when pulling away.  When on the move there is no perceptible noise

When driving the sound appears to come from the drivers side rear put upon further inspection with Rob at Ratrace it may be passenger side rear and the sound is traveling.

Things i have done/checked:

Spanner check of rear axle, suspension and brakes

Replaced the rear shocks/springs - a necessary upgrade required anyway

Checked the diff for oil

Checked the prop UJ's and greased

Checked the wheel bearings

Checked the radius arm bushes - there is no visible movement when the car is held on the brakes and the clutch let out

Replaced the centre A arm bushes

Any other ideas?

Gearbox mount?  Something in the exhaust system (e.g. loose mount)? 

Try removing the tunnel cover and see if the noise comes from the same area.  As you say noises travel

Handbrake cable catching/knocking on axle casing?

Shock mounts - both ends?

Thanks for the replies.  I havent got as far as the gearbox mount so will try that at the weekend.

Handbrake cable was a possible but have protected/moved it so its not that.  Shocks are new, with new bolts and torqued up.

The hunt continues.

Another thought - do you have an old phone you could use to video under the rear end to see if it picks up something moving?
