Vibration Only When Accelerating: Causes
A shudder that appears under power and fades when you lift off has a classic cause. A Cranbourne West specialist explains.
What it usually means
Vibration that comes on under acceleration and eases when you lift off is the textbook sign of a worn inner CV joint (the outer ones click on turns; the inners shudder under load). Worn engine mounts, a bent axle or a driveshaft issue can contribute.
Wheel-balance vibration, by contrast, stays constant at a given speed whether you’re on or off the throttle.
What you should do
That on-throttle/off-throttle difference is diagnostic gold — note it and get it checked; a failing inner CV worsens and can eventually let go.
We road-test on and off throttle, then inspect the inner CVs, mounts and shafts to pin it down.
How we find & fix it
Because the same symptom can have several causes, we use dealer-level diagnostics and a methodical check to pinpoint the real cause — rather than throwing parts at it.

Classic worn inner CV joint — it shudders under load and eases off-throttle. Mounts or a shaft can contribute.
Balance vibration is constant at a speed regardless of throttle; this one follows the accelerator.
