Finally solved the problem:
At last I have got round to looking at the driveshaft pop out problem, having had it happen numerous times.
1. The rear engine mounting has 2 parts. a) The welded plate on the chassis and b) the hanging black metal support.
a) The welded plate has started to sag
2. There is an unexpected amount of movement of the engine/gearbox to the extent that it is hitting the auto gear linkage assembly under the gearbox.
3. Because of the layout of the rear suspension, when the car is hitting bottom, the left rear wheel is moved away from the gearbox which results in the following damage
A number of solutions are available but which is the best to opt for I am not sure. I could:
a) Support the gearbox to stop it dropping.
b) Insert a collar on the wheel universal joint bringing it approx 10mm closer to the gearbox.
c) Have a longer shaft manufactured. There is about 20mm of space inside the gearbox universal coupling that is not used.
OR
maybe someone out there has a better solution?
