Symptoms of worn Subframe Bushings and imporntant considerations Saab 95

Hello DIY mechanics, in this video I'll explain the symptoms of defective subframe bushing on the Saab 95 and show you exactly how to identify which of the 6 subframe bushing are worn out.

I also explain everything you need to consider when buying new subframe bushings so that you avoid spending too much money unnecessarily.

The symptoms range from vibrations to knocking of metal on metal at low engine speeds, when clutching, shifting and when starting and switching off the engine.
In a car with automatic transmission, you will feel an unpleasant jerk when changing gear, i.e. from P to R, N or D, an unpleasant vibration when stationary with Drive engaged and also a rough shifting process or a distinct jerk when changing gear.
