Thread: D4 Reliability

Front right in this case - not from roundabouts. Probably a combination of a bit of mud and a few "spirited" runs down from Hotham to Bright - lots of downhill right hand corners. I never saw it as it was replaced under warranty, but certainly a likely explanation.

I had same experience as you with all my other Discos though, so put this one down to bad luck.

Cheers,

Just someone who hasn't previously been stuck on the side of the road several times in a near-new vehicle. I recall being very annoyed at my near-new D2 dropping its front tailshaft onto the road when neither of my well-worn RRCs had any such problems.

Someone once tried to push me to do the same but I didn't play - too much tread to be sacrificed.

You think LRs are complex, try a diesel/electric haul truck. For a 7 odd million dollar machine they certainly pump out some fault codes. And they fail prematurely for all sorts of reasons, both electrically and mechanically. Machines all have potential to break down regardless of if they are cheap and nasty or worth millions of dollars.

Bearings most often fail long before their service life, and the 3 most common failures are installation errors, lubrication and contamination.

Possibly Komatsu?? I know the 930s we have come out with some codes and after its been raining you have to start them and let them run for about half an hour to dry the inverters and computers out hahah

Most long haul trucks are the same. My son in law's father drives road trains all over WA (usually pretty new Volvos) and he says the engine management lights come on quite often and they just have to wait by the side of the road for a mobile mechanic to come from 100's of km away to fix them up.


On a recent trip from Darwin to Perth we passed three road trains on the side of the road or pulling off the road, talking on the radio about how their truck was in reduced power mode due to some electronic problem. These were all in the Pilbara, a long way from anywhere. Also, one late model prime mover that was completely burnt out and not much more than a heap of melted aluminum.


Seems to be the way things are heading in the name of fuel efficiency and reduced emissions.

I have a mate who sold his Mack trucks and made the mistake of replacing them with Volvos. He ended up bankrupt and now drives someone else's (Kenworth) trucks on wages.

In my experience, Volvo trucks should be confined to built up areas and freeways - they are bloody rubbish in isolated areas.

Now where have I heard that before
