How do you know if your Jeep will get through a piece of terrain?

So I went up and checked out a local off road park (federal off highway vehicle park) today by myself and uh, well it went well except for one incident. Let's just say I "broke in" my new JKU with it's first scrapes on the underside of the bumper and a little stress on the air dam push pin things along the front edge. Oh and one of the crush can areas the plastic bumper cover kind of got stretched on the bottom edge of the can underneath and had a bulge. I managed to fix that with a hair dryer on high and a metal can rolled on it to flatten it back out

Here's the pic of where it happened. The bumper took a faceplant where you see the red circle. I think I might have actually made it with bigger tires and a few inches of lift, but oh well. I was actually just creeping down the hill but the stock SR-A's slipped on the last couple of inches and that's why I smacked into the ground I guess other than experience the only other thing that might have saved me would be a 2nd person/spotter saying "hey stupid you can't make it down that". The funny thing is I wondered if I'd make it before I went down it, but I didn't expect the tires to slip.

Part of learning your Jeep's capabilities. Next time you'll know.

Always put a tire on the high spots and get rid of the plastic air dam.

Your tires slipped because you used your brake--

Going uphill/downhill (off-road) you should ALWAYS try to be in the best GEAR, so that you won't have to touch your brakes--

As soon as you touch brakes, even when ESP is off and you're in 4lo/4hi-several of your tires will lock for a moment---soft dirt/sand/snow/ice and you lose control --

Another point--when ever crossing a berm (speedbump)/rut/crevice-check SIZE/depth first for safety--then cross AT AN ANGLE and that will protect your bumpers/skids/driveshafts/ego-etc

As Kb says--you need to LEARN your jeeps abilities off-road--you can get info/training/video, but you have to DRIVEIT !!

Good luck

JIMBO

If the crevice is very steep, but not very wide then I go straight through. It helps having a really good approach and departure angle.

Which is totally different in a 4 door.

Trial and error, trial and error.

At least you picked some fairly soft ground to find out on.

Actually, this is just one of the many reasons I never wheel alone.

If it is a trail or obstacle that I have never been on, it always helps to watch someone else go through it first. Study the line they take, and notice where clearance issues might affect your Jeep.

Doesn't always work, but it helps. If you like to wheel your Jeep, beauty marks can be expected. It is the first one that hurts the most!

you don't always know, but you have to try.
After driving it for long enough you will know what you can do and not.

It's a jeep. Take out back out and scratch the shit out of it! Then rattle can it. Seriously, you can't learn the limitations of your jeep until you exceed them. Just hope your not alone and it's not terminal.

LOL no aerial but yeah the pic was taken a few feet back up the hill looking down into the rut. Was kinda steep, the other side was not nearly as high. Yeah guess I just need practice and I agree with it being a good idea for me to follow a friend. The silly thing about that is that's the reason I was there in the first place was to check it out and see if it was worth it for a friend to drive down here for. I was playing around on my own, did so well getting up a steep hill (my first time in 4L) that I guess I got over-confident and next thing you know the wheels are at the bottom of that rut and the bumper is just below the top and I'm just sitting in the drivers seat going

Edit: I don't know if 4L would have saved me from the slip & bump (this is aimed at Jimbox) unless it really applies some serious engine braking. I was already lightly on the brakes and maybe going 1mph when the tires slipped on the ground (in 4H).

Width is the main thing we worry about around here getting between trees. Outside of that, you just get a feel for it. Its all about geometry, so you could get out and measure things, but you will get an eye for it pretty quickly if you wheel much. And, like the others have said, a few scars here and there remind you what you bought a Jeep for in the first place.

Going downhill with a stick and 4lo, unless you're driving off a cliff--you'll ALMOST never need the brakes applied and with the Rubi/4lo/auto thats pretty much the case too--

I'm even spoiled more by having the regearing--I can drive "DOWN" trees in 4lo/without brakes--pretty close to the crawlratio of the Rubi stick in 1st gear ~

There ain't no reason forit--it's just the way we doit !

That's very irresponsible; you should OPEN your eyes and floor it! That way you don't miss a chance to wave at someone doing the same thing in the opposite direction!

A number of "supposed" reasons--

Increase aif-flow-entotal-reduce vehicle drag

Protect the oil filter and the front underside of engine-

There's a small group that believes the AD reduces the "lift" effect on the hood---at speed -

increases vehicle weight at 80 mph +, (airfoil effect) !

It's a jungle out there

Also provide a " very small" bit of protection to the Rubi's sway disco motor.

That being said. Ripped it off on Saturday

I don't own a JK but I saw a video on YouTube from metalcloak about their frame built bumpers and if you watch the installation video for JK's it shows that you can move the sway bar disco thing up to gain clearance and keep it out of harms way. You have to do very little plastic trimming but it's well worth it to me IMO to save from smashing that electric disco.

So after reading all this, I think I'll throw away the front Bumper on my JKU, and build a big assed Lawn roller thing like the WWII half Tracks used and mount it up front....that should help on the approach angle..... LOL "BH"
