Hello, all. Long time since my last post - which was probably another question...heh.

Anyhow - I'm wondering "what is best way to tackle a loose rock section of trail"?

On Thursday and Friday, I decided to take a couple of days off work and try a new trail (to me) here in Arizona. My trail running experience is very limited, I still consider myself a n00b. Mainly stuff like "front way to Crown King", or a run to Sheep Bridge or Horseshoe Dam. Mostly dirt, with some small rocky sections, ruts, light water, etc. My TJ isn't outfitted with big axles or anything...it's no Rubicon...lol.

I just like to go out every once in a while to have fun, otherwise right now it mostly sits (because I work from home now), even though I call it my "daily driver" (at one time, I used it to "commute" to my work mostly). Since it rarely sees more than my driveway, though, I figured that now I have another job and can afford driving her again, why not some weekend fun on a trail here and there?

So - this new trail was something I thought would be in my same "comfort zone" - Table Mesa Road from the I-17, east to the intersection with Seven Springs Road (then a leisurely ride on that road back home - I love the area, and am somewhat familiar with it, since all you need is 2WD for the Seven Springs area, mostly). I had decided to do a "forced overnight" - starting out from home at 5:30pm, over-night camping (ie - sleeping in the Jeep) somewhere before the turnoff. I had hoped to get close to the turnoff before camping...

...but boy, was I wrong!

I have honestly never been on a more challenging drive off-road than this one. There were at least two times I thought I was going to be stuck but good, and have to be rescued (I left info for everything with my wife - if I didn't come home by midnight on Friday, send a search team - AZ 4x4 Offroad Recovery, etc). I don't have a winch on my TJ yet (next thing on the list, especially after this run!) - but I have a large hi-lift jack, jackmate, long length of chain, straps, etc - you name it, I probably took it with me - just in case I needed it.

What I encountered more than one time in the area, as the trail wound beside, in and over New River and various washes - were areas I called "rock fall" - it seemed like a bunch of loose rock, 8" or larger - up to about the size of a small microwave - as part of the trail. I have some damn good tires on my ride - I tore the heck (pretend that was a different word) out of 'em (32" ProComp AT Extremes or something like that - 8 ply rated, IIRC - and I was running them at around 45 psi). I was being bounced around left and right, manhandling my steering (sometimes it manhandled me back!). More than once spit rock out the rear, spinning all four wheels, getting stuck, having to back up, try a different track. I was in 4HI most of the time, 1st or 2nd gear. I probably should've been in 4LO. I probably should've dropped the pressure in my tires. Even so, I made it up (and down) these areas - but each and every time I thought for sure "OMG, I'm either going to be stuck on these rocks, or I'm going to break something expensive getting past 'em!

There were several times I stopped, and looked over my Jeep to see if I had broken something. At one point, it really felt like I had seriously fubar'd my steering. I can't explain it - it felt - and probably looked like it (I wish I had video) - I was slamming and bouncing hard over these rocks - doing anything and everything I could to avoid "stopping" - keeping my momentum going forward. More than once my tires scraped the insides of my fenders. More than once I "burned rubber" scrambling up these areas. More than once I am sure I hit the bump stops on the suspension. I honestly don't know how all the crap I had with me inside the cab didn't become beans rattling inside a can - but somehow, it all stayed in place...

One time (after I had broke camp the next morning, on Friday), I got stuck in such a way with a rock behind one of my front wheels that I couldn't move forward or backwards. Even steer hard left and right, rocking, etc - nothing would break things free, but I could see that the wheel (when I steered) did move the rock around. I ended up getting out, shifting that rock back by hand, then stacking some rocks behind the rear wheels, because I was on this "ledge" with about a 9" drop - and I needed to back up some, and then "launch" toward the right, away from some larger rocks on the driver's side, and up other rocks on the right. After making those adjustment, I got back in the cab, said a little prayer to a non-existent deity, patted my Candi urging her to take me home, and went for it. I made it up, somehow. But that was just one more in a long line of such "scrambles" up these rocks.

If you ever played with the old Stompers toys on one of the old foam and plastic playsets, and watched your vehicle bounce around while tackling the terrain - I swear that is what it felt like to me - almost all 19+ miles of that trail to the turnoff. I was led to believe it wouldn't be much more severe than maybe the last time I went to Horseshoe Dam - I thought it would be rough, but I had no idea it would be as rough as it was - rough to the point that I thought I was either going to get stuck, be stuck, or break my Jeep trying to not be stuck.

Well - I'm here typing this - so you know I made it home. Amazingly, I haven't found any damage. Drove it home from Seven Springs thru Cave Creek and all the way back to my home (which is roughly near 51st Ave and Cactus) - steering was fine, handling was normal, everything felt "normal". No CEL or anything like that; I still need to check underneath to see if scraped anything, but I don't think I did. Tires are chewed up like a dog toy (but I needed new tires soon anyhow), but amazingly, my wheels look as good as when I started (I thought for sure they'd be chewed up too). No punctures in my tires that I can tell. Air pressure still holding in 'em...

So I'm wondering - did I do things wrong? I mean, by the above, you might think "well, you got home, didn't ya?" - but I'm wondering if my "look at the course ahead, keep it in low gear, and send it!" is really the right thing to do? I know for sure I should've probably have been in an even lower gear (4LO) for some of those areas, and maybe dropping the tire pressure down some (30-35 psi?) might have helped with the climbs...but I'm wondering what experienced people do?

And is my thinking wrong that this kind of trail was hard for my experience level? It was definitely out of my comfort zone, more than I had planned or hoped for. I don't want to stay in an area of comfort, I want to expand my knowledge and comfort level - and this trail definitely did that! I'm just wondering if there is something else I could have done to make those areas easier on myself and my rig?

Finally - this trail/road/whatever-you-want-to-call-it - is actually one of our "forest service roads" - it's one of the few ways going between the I-17 and Seven Springs (to the north, there's another trail I want to try, called "Bloody Basin Road", that is also one of the east-west paths in the area - maybe I'll find out why they call it that - sigh). What I want to know is - what kind of rigs do they run to get over these areas - for rescue, fire fighting, floods, etc? I mean - I can't imagine using roads like that in a real emergency - but they have to, right? So what are they using - and do they get jounced around as badly as I did?

Saturday and today, I've mostly spent eating a bunch of ibuprofen, drinking coffee, resting, etc - I'm super sore and beat up, and I did no favors to my lower back. But the next few things I want to get put on my Jeep is a front skid plate, maybe some kind of "armor" for my steering box and diffs, and a proper winch and bumper for the front...
 
Sounds like you had a great time! I remember the euphoria of my first times wheeling and it was equally fun and exciting.

For starters, air down those tires! You mentioned airing down to 30-35 psi, and that’s just insanely high. Most folks here run around 26 psi on the street.

If you’re running 32” tires with 15” wheels, then on the trail you should be pretty comfortable airing down to 12-15 psi.

Secondly, disconnecting the front sway bar links will help a lot with what you are describing! It takes just a couple minutes, but makes a massive difference offroad.

These two things are the absolute cheapest ways to gain traction and ride quality when on the trail.

That was too long to read, but I laughed my way through several paragraphs.

45psi?

4H?

Air down to 10psi and put it in 4L. You don’t need momentum all the time. Take it easy.
 
Dude.

That was a great read. I chuckled quite a bit.

As others have said, airing down and 4LO make a big difference. I'd start around 12psi and see how that does for you. When you are looking at winches, look at a small air compressor too, even if it is the type you plug into the cigarette lighter. That way, if you have to drive a long way home after tackling a tough trail, you can air back up to street pressures.
 
Can someone give me the cliff notes?
For 32" tire 45 psi is absolutely the wrong pressure to run on the street, that is WAY too high. Don't think the pressure molded onto the sidewall is ever the correct pressure to drive on, that's only is maximum safe air pressure. For that size tire on the street, run 27-29 psi.... 27 psi when your Jeep is lightly loaded, 29 psi when it's fully loaded with people and/or gear.

For the trails, air way down... especially for the type of trail you were on. 11-13 psi would have helped immensely and been totally appropriate. You're not even aired down until you're below 15 psi. No your tires won't unseat at those pressures.

4Hi is very seldom the correct mode to be on for offroading. You should only use 4Hi if you're trying to maintain speed like on a muddy dirt road or deep sandy trail. For anything else be in 4Lo. 4Lo gives more low-end torque for getting over obstacles but mainly, its lower speed gives much better control on difficult terrain. Being in 4Hi and with 45 psi in your tires would, indeed, have been absolutely horrible on that type of terrain.

Lastly, and my bet is you learned this, never wheel alone. There's always a good possibility of breaking something vital when on trails like that, especially since you were so new at it that you didn't know how to tackle that type of trail which is the main cause of damage. Join a Jeep club and get some experience by wheeling with those who are experienced.

Otherwise you survived and learned a lot of great lessons, that's awesome. And, oh, did I mention to never wheel alone? Congrats on not breaking anything and having learned more in one evening than many learn in many trips. :)
 
That's a great trail. A bunch of us here ran it a couple of months ago and it's definitely gotten harder in the last year with all the rain and erosion. I've only run it on 31s with open diffs; by implementing what's been suggested here, your TJ is more than capable of making that an easy run with a couple of moderate challenges sprinkled in.
  • Lower your tire pressure; 12psi is a good place to start
  • If you don't have them, quick disconnects to disconnect your front axle will help greatly; if you want to go all-in an Antirock or SwayLoc front sway bar, but they're spendy
  • 4Lo is your friend for crawling slowly, and in control both uphill and down. Way less need to focus on speed going uphill and saves your brakes going downhill. Experiment with 1st/2nd gear depending on grade and terrain
  • 4Lo is also your friend in the rock gardens where a little more torque will allow you to progress slowly and under more control with the open diffs
If you're interested, go to this sticky thread, tag @Chris and have him add you to the list so you get notifications when we post a run. There's a fair # of us at all different experience levels that will post and run trails together.

Brother?!!! Longtime no see. I grew at 45th ave and Cactus. Moon Valley Class of '90.

I'll start with the bad news. Most of us will not be wheeling again till October. Too hot.

Good news is, you already have an account here. Add your name over in the AZ thread. Ask questions.

Through the site here, made my 2nd ever trip and it was that exact trail. All the Jeeps in this pic are of fellow forum peeps.
