  1. Diesel derated/power loss--solved by Z96 Safety Recall

    BLUFF: I had multiple instances of power losses driving up steep highway grades, the "Service Electronic Throttle Control (ETC)" message and Check Engine Light (CEL) illuminated, and the vehicle remained drivable but with reduced power. After stopping and restarting the vehicle, power was...
  2. Lasfit Hood Lock – The Good, The Bad, and The Install

    I just installed the (deep breath) Lasfit Stealth Anti-Theft Automatic Hood Lock System on my JLURD. It’s a fairly easy install and the directions are really good with some clear color pictures. But there are a few things to point out that Lasfit doesn’t clearly address. Install notes: -...
  3. I need help with an oil leak, please.

    I’m by no means an engine, diesel or otherwise, expert so I’ll take whatever you all suggest as gospel. My 3.0L has suddenly developed a peculiar oil leak that I’m clueless on where it’s coming from or what has caused it. It’s still under the original 3 yr./36,000 mile warranty but I’d like to...
  4. Turn Aux battery into a spare?

    I was reading the recent https://www.jlwranglerforums.com/forum/threads/night-recovery-jlur-has-electrical-breakdown-on-badge-of-honor-trail-and-pulled-to-trailhead-until-2am.114135/ where a failed battery led to a long and difficult recovery off the trail. I have the aux disconnected per...
  5. What are the forum rules?

    Anyone have an idea where to find the forum rules, guidance, restrictions, etc.?
  6. 3.0 injector cleaning to increase MPG?

    I mentioned to the dealer that I was seeing decreasing MPG on my 21 JLURD, and he suggested injector cleaning at ~$300 at the next oil change. I normally take the dealer's suggestions with a grain of salt, but I'm hoping some of you have informed suggestions. Stock, I was getting ~25-27 MPG...
  7. AZ Peace Trail 1st Feb weekend

    Just seeing if anyone wanted to tag along. I got a soft plan on running part of the Arizona Peace Trail (AZPT) from Kingman to Quarzite/Salome 4-5 Feb 2023. If need be, I could be talked into making it 3-5 Feb. No detailed planning--just casually following the published trail and taking side...
  8. Is it worth carrying a chain now that synthetic straps and shackles rule?

    I've always had a chain in my 4x4 since I got my first Warn recovery kit that included a chain with hooks. But now that I'm phasing out the steel winch line and shackles, I'm wondering what function the chain serves. I also use recovery and tree saver straps, plus carry a Hi-Lift.
  9. Payload vs Upgrades -- a cautionary tale

    Much has been discussed in these pages about the low payload of our Jeeps and that adding armor and other upgrades could significantly affect the available cargo weight available. From experience with previous vehicles and the disadvantage of excess weight in off-road performance, I planned this...
  10. Looking for trail suggestions Vegas-Havasu area

    I'm visiting family and friends in the Las Vegas and Lake Havasu City areas and might be able to get together with a fellow Jeep driver. We're unfamiliar with local trails so can anyone recommend some trails to attempt? We're both on 37+ tires and experienced, but not looking for body damage...
  11. Chrome wrap

    A friend recently spotted this Wrangler in the DC area. Wow! Does it belong to anyone here? It's definitely different.... I can imagine this is one way to dissuade tailgaters under certain lighting conditions. 🕶
  12. Washington Sold: Rubicon suspension rock sliders skid plates takeoffs FREE

    $200 FREE Factory suspension and skid plates removed after installing aftermarket kits. All items removed from a 1-year-old 2021 Jeep Wrangler Unlimited Rubicon Diesel (JLURD) with the factory steel bumpers. Since the springs came off a heavier diesel, installing them on a gas model will...
  13. "Press Brake and Push Button to Start" screen stays on

    Anyone have a remedy? Last night I noticed my "Press Brake and Push Button to Start" screen on the center dash panel stays lit while the Jeep is off (didn't go off all night), even when FOB is removed from the vicinity. After I noticed it, I started the Jeep, drove it around the block and shut...
  14. ECM vs PCM, or both...and DTCM, FPCM?

    Do we have both an ECM and PCM? I was looking at the fuse chart and noticed F76 said ECM for gas and PCM for diesel. But then F38 says ECM for my diesel, and F22 has both ECM and PCM. An internet search resulted in an article discussing how older cars had ECM for the engine and newer cars have...
  15. 392 XR Whoops! Overturned @ Cleghorn Trail [Recover Video Added]

    Somone (w/limited 4x4 experience) in a 392 XR having a little too much fun on SoCal Cleghorn trail this weekend. I'm told no one was hurt and they were just waiting on the tow truck for recovery. All secondhand information, but a cautionary tale in any case. Updated with recovery video:
  16. Need help with 3.0 Diesel ignition system wiring

    RE: https://www.jlwranglerforums.com/forum/threads/jeep-jl-wrangler-wiring-diagrams.19185/ I want to wire an anti-theft engine-kill switch in my 3.0 diesel (not the starter). However, I don't want to risk destroying it by cavitating the CP4 HPP if the system activates inadvertently. On a normal...
  17. We recommend you use Mopar® DOT 3 Brake Fluid, SAE J1709

    This is from my owner's manual. However, I can't find any Dot3 brake fluid that meets SAE J1709 standard. If I interpreted some web pages correctly, SAE J1709 standard was cancelled it 2006. Can anyone shed some clarity on the subject, besides "don't worry about it?"
  18. What if: How to remove oil from cylinders after rollover?

    Just want to be prepared as I've had to do it twice before on gas engines. If the vehicle sits upside down for a few minutes, oil makes it past the cylinders that doesn't fully drain back after setting it right side up. If the engine is cranked as is, there is a likelihood of hydro locking. On...
  19. Using Hi-Lift with OEM steel bumpers?

    Any tips for using a Hi-Lift jack with the OEM front & rear steel bumpers? The large runner doesn't work with the rounded steel bumpers, and the bumper lift/lift mate accessories don't appear to be a workable option. I've thought of some possibilities, but maybe I don't have to re-invent the...
