While changing the front left wheel on a Ford Ka, the screw jack supplied with the car suddenly collapsed without warning. The screw thread was in good condition, lightly oiled over paint indicating the first use of the jack. The jack foot was vertically below the correct sill jacking point, extension did not exceed 355mm. Failure was caused by the pressed steel sides spreading and the plastic threaded boss popping out. The car is year 2005; 47,000 miles.
Is failure of plastic jack components a normal occurrence?
Fortunately, the replacement wheel was already on and the nuts half tightened. The free drop was 10mm before the tyre touched the ground. But the next day, the car failed the MoT with two broken front coil springs. Could this be related?
