A driveline clunk when lifting off the throttle
A clunk from under the vehicle at the moment you lift off the accelerator or reapply it — the transition between driving and overrun. This is driveline free play being taken up in both directions.
What can cause it
Worn differential or driveshaft components with excessive backlash
A worn universal or CV joint
Worn transmission or differential mounts
What to check first
Note whether it happens on every throttle transition or only occasionally
Have the driveline inspected on a lift for play at each joint and at the differential input
Check the differential fluid level and condition where applicable
Have mounts inspected at the same time
What this symptom does not tell you
An observation narrows the search; it does not identify which of the possible causes applies to your vehicle. Confirm the cause before any part is replaced — several of the causes above produce an identical symptom.
Possible causes

When to stop driving / seek help
Drive with caution. Backlash grows over time and the components producing it carry the vehicle's drive torque.
