Axle Swap on JLU Sport

[StngrayVA89]

I'm going to start off with i bought a JLU Sport as the JLUR's are insanely priced right now and with the specific color and extras i wanted it was hard to find a JLUR.. That said i have already spent what it would have cost to buy the JLUR (my wife doesn't know that..yet).

I am waiting to put on some 37's along with a 3.5" RK X factor kit, with Fox Performance 2.0 Res shocks, and gear to 4.88. I have already spoken with a couple of you (@Roky and @hoag4147) who have been extremely helpful. After listening to the guys and doing some of my own research, I've realized that swapping axles may be more beneficial than attempting to see what happens on the Dana 30/35s. Thus id like to know everyone's opinions, should i swap to the Mopar Dana 44s M210/220, and gear to 4.88, or should i go even further? For reference, i do not plan on doing any rock crawling or extreme off-roading. This is my DD, and will be used on trails and mud in Florida.

If you can find a good deal on some rubicon take-offs I would go that route. Otherwise with your use case I might be inclined to just gear your factory axles. The only caveat is that if you do get more into off-roading down the road you will need to think about an axle swap.

Are you doing the work? If so, chuck some gears in it and see how that goes. If you're paying for it, don't bother and just get some take off 44s.

Axle swap. A set of Rubicon takeoff D44s makes a lot of sense, especially if you find some geared to 4.88 or 5.13 since you’re going to 37s.

I vote rubicon axles. But unless you find a set for great price geared whatever you want them to be geared (saw a set recently), go with new crate axles. Surprisingly they might be the almost the same price as used. People very rarely change axles before abusing the ones they have.

I appreciate the input, this is what i gathered to. Seems to be the more feasible option at the moment as well.

I currently dont have the space or tools to do it myself, i mulled it over the weekend and im going to go with takeoff 44s

This has been my main concern between buying crates or takeoffs. I am going to see what the market in my area yields. If i can get some takeoffs with the gear i want i think ill just go with those and hope they arent too messed up. I live in florida so i would imagine other than trails and mudding they wouldnt be overly banged up.

JLR/JLUR axles seem to be a lot more available on FB/CG/etc... Personally, I would find some take-offs and utilize those, especially for your application. You can always add-on (truss, chromoly axles, etc) should you want to get into more aggressive stuff but have a better peace of mind.

I am thinking about the same thing I have a diesel sport and would like to buy crate only, so will I be able install the electronics on the dash or what's the options, what about bigger brakes etc?

Some of these crate axles are priced real good here, a Rear D44 Rubicon crate is $1123 w/ $60 fedex ground shipping (only 1 remaining however), even some rear Dana 70s going for some pretty good pricing although I have no idea what extra fabrication, brackets, etc would be req'd to get them to work on a JL. Also from the pics it looks like axles might not be included, have to verify all that prior to order confirmation.

That's crazy good price for the rear! too bad I already have mine

Yeah, can't even get a re-gear for that price. You wouldn't happen to have the part # on your F&R crate axles handy by chance? Would be good to see if those #s on rockauto are the same since I can't confirm if they actually come w/ axles. TIA.

 

[El Zilcho]

I used this part # for the rear : 77072406 Front is 77072405

I have been running Falken AT3W 37" tires on a fresh stock axel for 35k miles in one year. I do not off-road at all, but it has been my DD for 3.5 years now. My stock axel got busted before I did the Mopar Lift + 37" tires ; the replacement axel was covered under warranty. Go ahead and look on the forums for more info as it affected some folks without any mods. I got lucky! I had not visited a dealer for anything other than the install of the kit and tires, and they replaced the axel for me, again under warranty 52k miles at the time.

All I have done since is recalibrate the tires and the 2018 Etorque 2.0T still gets 22 MPG down from 28ish at stock. I have not regeared and I still see 8th gear.
