I started this reply out in a very nasty manner, then realized it wasn't worth it. Sometimes, there's just no reasoning with folks. Plus, I don't know you, so I'm not going to make personal attacks. And BTW, I don't smoke peyote, but I am drinking a glass of wine right now. So let me just try to clear up a few of these misconceptions in as objective a manner as I can.
I still don't know where you're getting this plastic parts idea, if you've ever been under a
real Land Cruiser, you'd know that there is nothing plastic under there (except splash guards and crap like that on the newer ones, which are not mechanical components and therefore moot for this argument). Plastic bushings? Not on any Land Cruiser I've ever serviced.
This next one is actually kinda funny! The latest FJ (I assume you mean FJ Cruiser, especially judging by those pics of yours) is
not the same thing as the heavy duty Land Cruisers that I am talking about (40, 45, 55, 60, 70, 80 Series, etc.). Let me repeat that again: it is
NOT a Land Cruiser. It is in fact built on the light duty Prado/GX/4Runner platform. I wonder if this is the source of all of your other mis-statements? For example, the FJ Cruiser does in fact have large plastic inserts in its hood, so maybe that is where your "plastic hood" comment comes from. But I can tell you that a real Land Cruiser has all steel up there, buddy. Please try to get your facts straight before posting this drivel.
You have a whopping statistic of exactly
one for the idler arm housing. And was that even on a Land Cruiser, or was that on an
FJ Cruiser (now everything you've written previously is suspect to me). Anyway, that is statistically insignificant. I personally have never seen or heard of this on a REAL Land Cruiser.
Big-end bearing problem was in one run of bearing caps for the 1HD-FTE engine in 1990. It was fixed. Other than that, this engine has been faultless, let alone the previous H, 2H, and legendary 12HT before it.
And yes, all those 40 and 50 year old Land Cruisers running around, getting regularly pounded on the rocks in the U.S. or corrugations in the Outback, they sure can't stand up to time and abuse.
I'm just not sure where you're getting your data that Cruisers won't stand up to the abuse over time, and are not even "remotely" close to G's in that regard. Tell that to all the UN peacekeepers, Red Cross workers, Australian cattle drivers, and African safari companies that abuse these things. So I've gotta call b#(($#!t on that one, unless you can give me some verifiable sources (no, not car test mags, or one-off experiences of friends - show me the entire body of work).
238 mm. minimum ground clearance. That is certainly more than a stock 460, and even more than a stock 463 (211 mm.), so the Gurkha must use taller suspension coils or bigger tires. However, even at 238 mm. you have still not beat a factory stock FZJ80 Land Cruiser, not by a longshot. Minimum height at the lowest point (bottom of diff pumpkin) is 10.8", or 274 mm. (rounded down). That's more than 20% higher than the Gurkha. And don't talk to me about UNIMOGs. I've owned two of them. Capable, but the Cruisers were actually much more pleasant to wheel.
On my pics, I never said they were stock. Sure they have suspension lifts and bigger tires. But the components in question: axles, diffs, frame, even steering in the case of the 80, those are stock. The argument was about durability, and my point was that the components on a Cruiser are easily up to taking severe beatings, all the time. Also, put a G on bigger wheels and a lift and it will still NOT do that, or at least not nearly as easily. Unless you like teetering on two wheels a lot and leaving butt cheek imprints on your seats because you're clenching them so hard. I've witnessed it. Scary.
As for the axles, I must have mis-read your post (#22), where you state:
"The axles on G are standard, the Gurkha uses MB 307D axles in rear which are rated at 2.75t and Hanomag in front rated at 1.8t, it comes stock like that." I took that to mean that you were saying the axles on the G and Gurkha were the same and both were standard issue. If that is not the case, my apologies.
