  1. Build Advice Please (40’s)

    I was thinking about the 2-3/16" wrench I needed for the adjustable control arms, but I agree, I can't remember breaking out my 3/4" drive for anything besides trailer balls. Do you need a cage? No. especially if you never plan to roll your Jeep. Of course, nobody plans to roll their Jeep. But...
  2. Build Advice Please (40’s)

    This is like saying "I'm deciding between 3/8" and 1/2" drive socket sets. The 3/8" goes up to a 3/4" socket while the 1/2" goes up to a 1" socket. What percentage of work can the 1/2" handle that the 3/8" can't?" The answer depends on the kind of project you undertake. Typical homeowner? 3/8...
  3. Clutch Recall (2/23/23): Clutch Pressure Plate May Overheat -- Affecting 70,000 Manual Jeep Wranglers and Gladiators

    Point taken. I too am a retired software developer and mechanical engineer. This is why I'm hoping someone will do the boundary test with a single tire 2" smaller in diameter. If that doesn't trigger limp mode then we don't have to worry about worn tires, curves in the road or how far it is to...
  4. Clutch Recall (2/23/23): Clutch Pressure Plate May Overheat -- Affecting 70,000 Manual Jeep Wranglers and Gladiators

    Did you ever drive it with correct gear ratio and incorrect tire size settings? I didn't think so.
  5. Clutch Recall (2/23/23): Clutch Pressure Plate May Overheat -- Affecting 70,000 Manual Jeep Wranglers and Gladiators

    As @beaups pointed out, the wheel speed sensor is upstream of the tire. You can put a set of whatever size tire you like on and it can't impact the software. Having an accurate size is important to calculate fuel economy, distance to empty, oil changes and of course to avoid speeding tickets but...
  6. Clutch Recall (2/23/23): Clutch Pressure Plate May Overheat -- Affecting 70,000 Manual Jeep Wranglers and Gladiators

    Agreed. But I'm not talking about changing all four tires. What if the coders derived target input shaft speed from rotational rate of the front tires (say 33's) and actual input shaft speed from the rear tires (say a 33 and a 31)? This is one of the two ways I would have done it. The other is...
  7. Clutch Recall (2/23/23): Clutch Pressure Plate May Overheat -- Affecting 70,000 Manual Jeep Wranglers and Gladiators

    Yes and no. You will be able to install the ACT clutch but you won't be able to remove the software nannies that are protecting the weak OEM clutch. This software appears to be comparing engine RPM with the antilock wheel speed sensors to detect slip. If the numbers don't match you go into an...
  8. Build Advice Please (40’s)

    True. But it’d be a lot easier and more comfortable on 40’s. I noticed nobody on 37’s followed me through this rock garden, even though I walked it without even a spotter…
  9. Build Advice Please (40’s)

    Spot on. Ford offered 4.30 gears and electronic locking rear options but good luck finding those hen's teeth...
  10. Build Advice Please (40’s)

    True. I ran the numbers once (mechanical engineer here) and was surprised that axle stress due to rotational load is very close to stress due to bending moment. Really surprising as these are totally different calcs. BTW, the issue with tire weight is when you are locked with spinning tires and...
  11. Build Advice Please (40’s)

    Sigh... If you even think you want 40's go straight to 35 spline axles. It will be cheaper in the long run. I wasted so much money on my front 44. This was a Chevy Dana 44 under a CJ-7, so not apples to apples but vehicle weights and power are remarkably close. In my experience you can run 40's...
  12. JL Offset & Backspacing Finally Answered!

    To be precise, the 9" wheel will move the tread outboard 0.25" and the inside sidewall about half as much, call it an eighth of an inch.
  13. Clutch Recall (2/23/23): Clutch Pressure Plate May Overheat -- Affecting 70,000 Manual Jeep Wranglers and Gladiators

    Yup, I too had high hopes for a redesigned clutch to address the issue. Luckily it looks like the aftermarket has stepped up to do what Stellantis is either unwilling or unable to do.
  14. Soft Shackle, what's your go-to?

    Given how much you wheel alone I’d recommend adding a pair of aluminum snatch pulleys. Or at least another snatch block.
  15. Uniclutch

    Oh, this looks cool!
  16. Soft Shackle, what's your go-to?

    Happy with my Custom Splice fangs in 3/8”. Durable, fit through 3/4” eyes, easy to attach after they’ve been used a few times, absolutely secure connection : https://customsplice.com/products/the-fang-soft-shackle-connection?variant=6498432221223
  17. Securing synthetic line to drum

    Yeah, never been the same after Vertiscope bought it. Still has some of the best tech on the web.
  18. Securing synthetic line to drum

    The type of fastener thingy doesn’t matter, it’s just to keep tension while you start the wrap. Friction of the wraps is what secures the line and you should NEVER pull with less than six wraps. If you have that much line out, you can loose tension on the drum so the best way is to secure the...
  19. Livernois Mycalibrator Tune Claims 50HP Gains (on E85) for V6 JL Wrangler

    That is the safe way to play it and for you it makes sense to stick with pump gas. I was precise with my words when I said the fuel system is designed for E85. Injectors, pump, tank and lines are all impervious to ethanol. However, the ECU’s fuel map doesn’t go past E15. It might go as high as...
  20. Livernois Mycalibrator Tune Claims 50HP Gains (on E85) for V6 JL Wrangler

    Agree 100%. The fuel system on JL’s and JT’s is designed to handle E85. The fuel system on JK’s is except for the fuel pump. The drop in range is the only real disadvantage to running E85 as far as I’m concerned. Well, that and availability. I’ve been running on E85, and only E85, for well over...
