What happens

Symptom. Knock from the rear over speed bumps, a hollow thump from the boot area.

Cause. The rubber mounts perish. On hard-used cars the mount can crack the surrounding turret metal, which is a far bigger job.

How to check it

Static checks

Lift the boot floor and look at the top of the shock towers for cracking or a lifted mount. Listen for a knock over bumps.

Engine off, ideally on a lift.

The last column is the point. The same repair is an inconvenience on one variant and a reason to scrap the car on another. A failure costing a quarter of the vehicle's value changes the purchase decision regardless of how rare it is.
