Thread: Murphy's Law, catastrophic failure in a very bad place

Failure in the things mentioned should be rare. Hoses should be checked so failure very unlikely. All landys should be built so a shock can be used on either side, and designed so a shock for another popular off road make can be used in a pinch. Otherwise it's not really designed for Australia off road use.

If the rear shocks fitted to earlier or non-CVD versions of these vehicles are not handed then perhaps one of those could be carried as an emergency spare. However with JLR's propensity for shutting down systems if 1 component isn't working, having the electrical connector for 1 shock's solenoid disconnected may trigger the shutdown of all CVD operation which would make for an excessively firm ride and increase the overheating risk for the remaining CVD shocks. Hopefully CVD continues to operate even though not all solenoids are functioning, which would be easy to test anyway.

I would think the Australian Off Road market is not high in LR thoughts in designing this vehicle,rather think horsey set, ski/snow, boulevard cruising etc.

It's still an amazing versatile vehicle, but the focus will be where the money comes from

One failure from an apparent gross overheat and you guys are talking down the design and mandating carrying spares?

Help, help, the sky is falling.

I think shock failure is frequent on those roads.

We are talking about remote area travel on heavily corrugated roads that kill hundreds of shocks each year. Carrying a few spares would make sense to most.

The shock failure appears due to one thing. Overheating.

If you can understand and mitigate the causes of overheating then you'll be perfectly fine.
Otherwise it's like driving with a plugged radiator and carrying a spare cylinder head.

The cause of overheating is travelling at the worst speeds where the shocks are working the hardest but don't have enough cooling airflow. The mitigation involves checking the shocks (IR temp readers are cheap) occasionally and slowing down to reduce the energy input or even stopping to take regular breaks.

You wouldn't keep driving the same way with an engine temp gauge hard into the red. So why do it to your shocks?

Is there some kind of RF temperature gauge you can stick to the shocks with a monitor readout you can carry in the cabin? I imagine there would be, somewhere, similar to the Tyredog tyre pressure monitoring system I use.

Maybe that would be a fairly simple and relatively cheap solution.

Just a matter of finding something that'd do the job....
