I can only find the Jeep Perfromance Parts (JPP) Mopar Dana M220 AdvanTEC wide rear crate axle for the 2021 Rubicon equipped with 410 gears. Otherwise, you have to do a ring and pinion change out to get the 488 in the rear, if you want to stick with JPP Mopar parts that meet warranty for dealer...

The issue is the ACC system uses, and relys upon, the windshield camera, which is partially obscured (and 'fooled' by) the large Codan HF antenna body, which is mounted on the front right bumper. The fact that the brains of the ACC may be mounted inside the box behid the widnshield is not the...

I forgot to add: I will have the 2” Mopar lift installed.

Great point! But, I'm thinking it should be OK, since this crate axle is sold as a JPP Mopar system, and it's in their JPP catalog. Would seem strange if that JPP part would throw codes, etc., but sure as heck, I am definitely going to ask! Do you have any idea if a JPP Advantek crate axle is...

Is there a Mopar part number for a complete AdvanTEK/Dana 44 Ultra Rubicon rear axle with 488? If I could go this route, whilst it would definitely be very pricey, I could be assured the entire rear end would be done correctly at the factory, juxtaposed to dealer re-gear. Albeit, I suppose there...

I doubt he's even aware or thought about no FAD, but why would not having FAD cause a dealer any sort of warranty issues?

The problem is I already ordered the front axle, and I assume it is not returnable, but I suppose I could be wrong.

Thanks, NachoRuby! This is why these forums are the bomb!

OK, gotchyuh. I am a bit conflicted, though, as it would be so nice and bulletproof to get rid of the FAD, in terms of a bit more strength up front, and no box to bust. But more importantly, I have read that going in/out of 2WD/4WD is so much quicker and smoother without the FAD mess. I test...

Good one!:) But that stuff is designed to avoid detection. With the size of the Codan HF antenna on my front bumper, my JT will stick out like a sore thumb from miles away!

I’m not understanding your logic here. If the “FAD equipped axle is a little freer,” then that’s exactly my point. I read a lot of posts saying that the non-FAD equipped axle causes noticeable drag, especially at freeway speeds. I assume another way of saying that is to say it “felt freer with...

Unfortunately, JPP/Mopar do not have a ring and pinion re-gear kit available for the front axle. They do sell a JPP kit to re-gear the rear axle. This would mean I’d have to go non-JPP aftermarket for the front axle. In turn, my dealer will not install it. Meaning aftermarket parts, let alone...

I may very likely cancel my order for the JTDR to change to the 3.6 Pentastar, based on all the problems with over heating on the diesel, thus my order specs vs/ disable scenarios. As to the glass replacement economics, since my CT is still several years out from delivery to me, realistically I...

I plan to give my JTRD to my son, just as soon as my Tersla Cybertruck arrives, which appears to be maybe in 2023-2024+. I ordered it a few days after it was announced in Nov 2019, so there are like 500,000 orders ahead of me. I want my son to have all of the JT safety features. He will not be...

Can all of this stuff be truned Off via OBD-II?

I have ordered 17x8.5 inch beedlocker wheels, with offset -32, and back spacing of 3.490 inches, to be installed on a 2021 Rubicon GladiatorJT. The tires are BFG 37x12.50R17 Krawlers. Am I looking for trouble here, in terms of rubbing?

So, for a 2021 Gladiator Rubi JT, there is no reason to install the crate axle, and inmsterqad simply instal a new ring and pinion to acheive 4.88? Why the heck is the passenger side not a two piece assembly? Why did Mopar and Dan decide to do this? I guess it's cheaper, but look at such a huge...

It is not RFI that I am concerned about. The HF codan antenna blocks and affects the view of the front camera, thus setting off all sorts of alarms with the auto cruise control functionality, and the forward collision warning systems. The trail cam is a non issue. It does not see the Codan HF...

I believe the windshield glass has a special coating for the camera to properly look through it that is not present on the non-camera equipped vehicle.

I plan to mount a big Codan HF antenna on the right front steel bumper of my JT, passenger side. This means I cannot have any sort of krap like the front camera(s), and any other such things like radar(s) and/or ultrasonic Parktronic sensors, etc. that support various functions like automatic...
