Thread: shock absorber ?

Hi all,

What does the car have, mono shock or twin tube ?

Doing some maintenance on the camper trailer and noticed the shock absorbers need bushes replaced. After some internet reading on suspension (not something i've had cause to do very often) I'm now learning about mono tube V twin tube and their different rates of heat dispersal.

Popular articles suggest mono tube is much better for corrugations. Due to the very frequent rates of low mm travel distances, heat builds up in a concentrated area. Mono seems better at dissipating heat, over the twin tube.

I've travelled many corrugation roads in a loaded D4 without every concerning myself about suspension. Now I'm wondering how the car is coping so well.

So you have to /really/ want the Konis!
You'll find there's a long running thread on the Konis, possibly started by TerryO, now in their second incarnation after the first proved unreliable.

How do they dissipate their heat energy away from inside the bag ? I wonder how much heat stress they go through on long dirt tracks. Or has clever Landrover cooling them somehow.
