Корозия на задната подрама: анкета сред 340 коли

The rear subframe on the X400 rusts at the front mount towers and along the forward crossmember. In a 340-car owner survey the first perforation is almost always the driver’s-side front mount, then the passenger side, then the trailing-arm pickups.

A tester’s torch goes to those mounts first. Surface scale is treatable. A hole you can put a screwdriver through is a weld or a second-hand subframe, not a can of cavity wax. UK and TR winter cars fail earlier than dry-state cars; the pattern is the same.

Jacking points are on the subframe. A jack pad on a thin tower will fold it. Use a beam.
