I hate to think it, but it sounds like a miss-diagnosis then. You didn’t give many details or relevant data, so it’s hard to guess. The Dana 44 is a good unit, even with lots of miles and hard abuse. Try the silly stuff now, like bent dust shields and slipped brake bad shims. If you have...

The instrument cluster display is configurable. You can set it to show you the gear selection all the time.

In a previous life, the standard procedure was to open an engineering ticket on any issue which wasn’t common or which couldn’t be diagnosed quickly. The manufacture didn’t want any tech spending warranty time doing diag. The dealers and manufacturer’s entire model was to hire the least skilled...

You are right Maximus Gladius. I'll attempt to send away for a sample kit today. If it's not here before I do the OC, I'll save a representative sample for later analysis. Update: After some thoughtful consideration, and because we are now going to dabble in some real quasi-science with the...

Approaching 9k miles. Time for another OC. No expressed issues with the 0-40w Euro. May go Rotella T6 this time. I’ll post when it happens and what I use. Still very pleased with the JT and pentastar. Towed some heavy loads and worked it pretty hard. Lots of redline-play. Driving...

I’ve never seen that done except on roached out and tired beaters. Your Jeep sounds the opposite if your going to pay for a wrap. If your applicator didn’t lay it on too thick, you might have enough clearance, but I’d worry about doors sealing effectively and quietly on the BL surface. Also...

Congrats. The Gladiator pulls very well and stable at reasonable speeds for me too. Real Floridians are born backing in trailers like pros. Only the transplants from states that the transplant has previously destroyed, muck it up. They also tend to super-fool if cameras are running.

Good info. I also recently towed very heavy with our Gladiator Willys. Towed so heavy, I had to put it in 4-low to get it to back up in my driveway. In 2-High, it would just rest on the converter while WOT in reverse, not moving —this is a normal thing for me due to the angle and length of my...

The Pentastar is a much better engine than we give it credit for sometimes. Every now and again, one let’s go and we attribute it to X, Y, Z. To me, this failure looks due to a mistake by an external action of someone who went inside it. The rest of the engine was in very good condition...

I do. They're rated to 55PSI cold, I believe. I like them there.

I live in the mountains and have a driveway so steep and long, people, particularly flatlanders, just cant comprehend it. That said, I towed heavy this past week. My JT ZF wold NOT push the loaded trailer up my driveway in reverse --just WOT and rested stationary on the converter. No matter...

Does the rattle go away when you simply rest your foot on the clutch and apply very slight pressure? Not enough to disengage the clutch, just enough to preload it? If so, it may be throw-out bearing. If not, it could be one of the shaft bearings or bearing cages that have failed or...

I think I agree. Extended idling will not hurt the Pentastar. Pentastar don’t generally have fuel dilution problems and don’t suffer from blow-by or carbon stacking like some DI engines. There’s a danger in thinking of oil pressure as an inflating ballon or tire, etc. The pressure required to...

Having one of THE most capable off road vehicles in the world, AND getting objectively great MPG is what separates us from the animals. Jeeps are not Prius —thankfully for that, I can still look my children in the eyes. When I catch myself getting upset about the pentastar not being a rocket...

iPhone GPS app shows indicated 80mph is actually 79.

FWIW, The mileage numbers I provided are hand-calc’d. That said, the instrument cluster is impressively accurate. Within .2-.3 MPG of actual, and once was shortchanging itself by .2 MPG. On my typical 126 to 128 mile round trip, it’s within a mile or two of what I believe to be true distance...

23 Willys ZF, all Factory, about 4500miles. 21.5mpg at 75mph using CC 19.5mpg at 80mph using CC Factory MTs at 45psi. No hyper-mileing behavior. I bet with low rolling resistance HTs, I could get 21-23ish.

HP Tuners seems to be the software all the Tuners use to create “tunes”. I’m not sure how powerful/capable the available tuning software really is frankly. I’m a recovering industrial controls guy, so I’ve done a good bit of programming, machine design, and process controls. In my world, we...

Interesting food for thought from another manufacturer: Ford says if you have the dealer install the factory performance package on a 2.3 Ecoboost or 5L 3rd-gen Coyote, which on both is ONLY a computer flash with zero internal engine mods, you must also run 5w50. The engine oil clearance...

Maximus is trying to do legitimate science. I appreciate his approach and the fact the he’s unselfish and posts his results. Fair warning though, some of the most senoir contributors will be verbally abusive and viscously attack you for daring to ignore the oil gospel in their Mopar bible...
