Clunking intermittently on highway

[Z2TT]

Hi,

In my VS When cruising on the highway at low revs, i feel a clunk in the driveshaft every so often.

I'm wondering what this could be?
Centre support bearing is good

Thanks.

Try cleaning and repacking the Lobro (centre CV) joint in the tailshaft.
Mark the two sections of the shaft so they are assembled exactly as they came apart.
Note: Dont pull apart the CV as they can be VERY tricky to reassemble.


It may also be the clutch in the lockup torque converter, but this usually feels more like a missfire.

i had a problem like this on my vt auto under slight load and low revs. mine was slightly missing, check your plugs and leads ect.

I'd also agree with the above posts - check plugs/leads as they can cause this problem.

Plugs+Leads are new. Can feel the clunk in the driveline area.

Could it be a DFI Module failing?

But really feels like drive train related, hard to tell whether engine is causing it.

Only other vibration is shuddering on takeoff in first gear.

Check ur engine mounts

it felt like drivetrain on mine too and i thought my auto box was stuffed until the problem got worse then it was easier to diagnose. i guess check anything that could cause the engine to miss or run rough.
