Hi, Guys.

Just flipped on National Geographic Channel today by chance and saw a show where the host was taking a 4wheeling trip up a Mountain in the Sani Pass at Lesotho near Southern Africa. This hill goes up 6000-9000 feet at least, and the road is accessible by vehicle. The host was driving a classic 4 door Land Rover wagon, white, with right side drive. I only saw the last 25 minutes of this so my description will not be as comprehensive as I'd like, but it will be brief.

When I turned the show, the host was about 2/3 up the road, and he had already lost the half shaft in his rear axle, and was going on with just front wheel drive. The terrain was about what you'd see if the unpaved sections of the road to Mt. Washington in NH was the whole road. The road itself was not difficult, but lots of turns and narrow in sections, and constantly going up for the most part. At one point, he came across a fairly steep section and couldn't make the grade with the Land Rover's front drive only operating. At this point, he turn the rig around and backed up this section, going very slowly. I presume he started this trip in the mid or late morning, and by this time it was afternoon, and the sun sets at about roughly shy of 6pm, so he now starting to fight the clock. He made it up the tough section and was continuing on. The scenary on this mountain was gorgeous, as breathtaking as virtually any drivable mountain trail you'd want to take, and as a photographer I was very envious.

The host continued on by his estimation for another 45 minutes when suddenly he felt a real jolt underneath his floor pan, and he looked for a safe place to stop and inspect the Land Rover. At this point, he lost his hand brake and had to back in part way into a ditch.

The drive shaft broke. Now he had no front drive, and the Land Rover was now and oversized paperweight.

Lucky the host had a satillite phone (and the Nat. Geo. film crew) and telephoned for assistance. Help came in the form of a Nissan Frontier-like 4 door 4WD pick up and he was able to tow the vehicle further up the road to spot where people can stay the night, and the host called for mechanical help to come the next day.

Help came in a Suzuki pick up with mechanics. They said the drive shaft was toast and could not be repaired on location, that would have to be done in shop. But they were successful in repairing rear drive, by replacing the half shaft, and the host continued a bit longer, then stopped his vehicle when he got to a tough spot not able to be run without 4WD. He got out and hiked to a spot where he was to meet with a guide who would take him to a secret spot where ancient native artwork was on rock walls. That was the end of the show for the most part.

Now the thing that gets me is, why was that Land Rover so delicate? I've wheeled twice since I got my latest 4Runner, and both trails - even the stock run at FG - was tougher than this mountain dirt road in Southern Africa. I couldn't help but to think that I could take my stock vehicle up that road right now and not worry about it too much. Ditto for any Land Cruiser owner or mini truck owner. The guys who went up the trail in the Nissan and Suzuki seemed to have no issue at all. I realize this is only one truck, and by no means do I mean any disrespect to Land Rover, who make good 4x4s, but that was a little shocking to see. I'm betting I could have made it in Ford Explorer.

Anyone have any thoughts? Just food for discussion, and I know it's difficult without seeing the show (hopefully it will repeat itself or maybe you can get it on On-Demand), but just wondering why this could have happned, short of being absolutely lazy on proper maintenence.

Several variables exist in the analysis such as maintenance, driver abuse, cargo management...but I believe the overriding cause is due to Design Margin. This is basically the fudge factor that engineers put into their designs which quantitatively expresses the maximum expected load (force or torque) to which a component will be subjected over that required for normal operation. IMO Jeep, Land Rover have lower Design Margins than Toyota which over 50 years has afforded Toyota their current reputation. Put 35s on a Jeep dana 35 axle and the same tires on Toyota 8"....see which one will break first.

As for Land Rovers..this admitted statement in Graham Jackson's Africa Overland Journal is enough for me. Considering the repairs necessary on the Defender 110s for his trip...its a no brainer.

"Our cars, whatever we choose, will most certainly break down at some point in the trip. There are recorded trans-Africa trips with no breakdowns, but these are mostly in Toyota Land Cruiser BJ75s"
 
I've spent a bit of time in the bush in South Africa and in Botswana, what I was told about rovers is: "They are for rich people that can afford to have a mechanic follow them around in a Toyota"
In Botswana I showed up in a 4door ford ranger turbo diesel (yes, I said this right. no mistake they have them in Africa) and I was warned that in Botswana you must drive a cruiser, nothing else is tough enough and if you breakdown you won't be able to get parts. We borrowed a 75 pick up for the rest or our time in the bush, no problems. On the way back to South Africa 5th gear went in the ford, we made it to the airport but I was informed that the tranny completely let go 20 miles later.
 
Makes sense. I couldn't help looking at the 4 door Defender and thinking I could make it up that trail with much effort. It's hard not to be a little cocky with your own rig when you see things like this. I would like to take that trail one of these years if I can figure how to ship my vehicle over there.
 
Sani Pass really isn't all that challenging in the dry. I have heard of guys driving up there in VW Golfs. In the wet, the road is slippery and becomes a lot harder. Being that high, it also snows on the odd occasion. There have been plans for many years to tar the pass but is still dirt at the moment.
