A little preaching...

It seems like holiday weekends bring out a higher percentage of bad behavior. To give the majority of you who ARE responsible public land users some ammo, here you go...;)

This is the sign we have in the office of our rental store. People think we don't like cleaning dirty Jeeps. That's not it. We clean Jeeps all day long. What we don't like are closed trails. We don't really like blown motors either, but at least those are replaceable--trails are not.


Self-explanatory...


Yes, close the gate, even if you are returning the same way later. The cows won't say "Oh, they'll be right back--we shouldn't go through this open gate..." Another excuse we've heard? "Well, we didn't SEE any cows...?" Lame. Close the stupid gate. Or we'll sick our stealth cows on you...


This just isn't for hikers. If you are heading into the backcountry for any type of outing, whether hiking, Jeeping, or underwater basket weaving...
1. Don't go alone.
2. Take water. Think about taking a few other things, too.
3. Look around. Pay attention. "Make good choices!"
4. Let someone know where you are going and when you plan to be back. No exceptions. 

We have heard this from many drivers with muddy or damaged Jeeps: "I just needed to let off some steam." Really? How much is a $5000 repair bill going to help with that?

Humble Pie


by Nena Barlow
15 December 2014

Flat towing back to the parking lot. You can see the small ruts alongside the road--that is what I hit at 30 mph that was the last straw...

Even when I am teaching, I learn something new every day. This is a good thing! I encourage clients to always look for the learning opportunity—no one ever “arrives” to where they know everything. We can always find new knowledge and continue growing.

Frequently, there is also the opportunity to reinforce “old” lessons. This week offered me just such an opportunity. Although I frequently joke about “Do as I say not as I do”, I had to eat that joke out in Glamis.

Imperial Sand Dunes, aka "Glamis": the easy, rolling hills in the foreground don't require the momentum that the taller, steeper, softer dunes in the background do.










My oldest work Jeep is Greta, my red 2012 Wrangler Unlimited Rubicon. Since this week’s training was focusing more on navigation and easy desert driving, rather than hardcore dune-running or rock crawling, I took this Jeep in spite of an ongoing mystery noise I have been hearing for six months now.  A noise I had been attempting to eliminate without success. It was a metal-on-metal light tapping noise heard since summer, when she is articulating or compressing. I replaced control arms, skid plate bolts, checked brackets and mounts—everything I could imagine. When I had Billy weld on two new nuts to hold on the front of one of my skid plates, I was sure we had finally solved it. But on the first day of the training on easy terrain, I heard that same old familiar noise. “No worries,” I thought, “She’s an old Jeep—she’s going to make some noise sometimes.”

Greta, loaded up for the trip.

Greta, not breaking a sweat on THIS trip, but she has known many aggressive trips in both soft dunes and big rocks, wearing down her bumpstops with time. 

Nice easy terrain for this trip, focusing primarily on overland navigation.

Now, those of you who have been on trips with me know that one of my pet peeves is when people say “It’s a Jeep, it supposed to make some noise.” My reply is always “No, if something is squeaking or rattling, something is worn or broken and you better figure out what it is.” Enter Greta’s mystery noise.

After a successful morning of dead reckoning navigation practice, we were headed back to the main road to move to another area. As the road flattened out to hard-pack dirt, I accelerated to about 30 mph, and just as I merged onto the main road, I hit a small tire rut and I heard that same smacking noise, but slightly louder. Suddenly, I smelled motor oil. I stopped immediately, hopped out and saw motor oil pouring out from under her. I quickly turned off the engine and then crawled underneath to investigate.

Ah--now I know what was tapping on what all this time...

Well, I found out what that mystery noise was. Greta is outfitted with an axle truss, which raises the total height of the housing about 3.5-inches. When she was outfitted with this 20,000 miles ago, along with new springs and bumpstops, everything worked together flawlessly. After 20,000 “Nena” miles, the wear on her bumpstops and the softening of her suspension was now allowing the top of the axle truss to tap the upper front part of the oil pan. And, with one last good jounce over that rut, I cracked the oil pan, exposing the oil pump and timing chain and spraying motor oil out.

I had the good fortune to be on a flat main road, so towing was the obvious option. If I was out in the middle of the desert, or by myself, or no way to get help to me, I would have been trying JB weld, duct tape and bubble gum to try to hold in enough oil to drive out.  If I had been simply on a private trip, I would have been totally focused on just getting back to where I could repair the Jeep. But, since I was in the middle of a training, the show had to go on. So, I called Jesse, 4 hours away in Sedona, to load up another Jeep and start heading my way. We dragged Greta to the side, transferred a few things and crammed in the other Jeep to continue with our navigation exercises for the day. Just before dark, we travelled back to where we parked Greta, Jesse arrived, we swapped Jeeps, and I headed back out into the desert to set up camp, and continue for another day. 

Jesse drove out with Josephine, towing Lilah on the trailer to swap out with me. Nice to have a backup plan! 

Those who know me well immediately concluded that I had a particularly spectacular airborn moment and hit really hard on landing. I will be the first to admit to many such previous instances (hence the status of the bumpstops), see incriminating videos here: 

...but this time it was just a small bump, like hitting a bad pothole that was the final straw. Did I deserve it? Not for that exact moment, but absolutely for all the others. Did I learn? Oh, yes, but not that the driving technique was poor, but rather that I didn’t listen to my own advice “if you hear a noise, you better figure out what it is…”

So, what to do about preventing this particular problem from occurring again? I am certainly replacing her bumpstops, new springs while we’re at it, and possibly considering some longer control arms to change the arc of travel WHEN I do bottom out again. This is the fodder for an entirely different article titled “What Happens When We Start Screwing Around With The Original Engineering”, but that is for another day.

The axle truss is great for NOT breaking your axle housing, but it reduces your clearance to the oil pan, and your suspension should be adjusted appropriately--either longer bumpstops or control arms.

As I write this, Greta is suspended on the lift, waiting for her new oil pan and pump, and I also see that her front driveshaft is starting to wear out. And is that a kink in her winch line? Sigh. Well, I also always say “4-wheeling is a pay to play activity!”
