(Update: JE Reel has been great to work with. Was a honest mistake and we learned how to delete the transmission heater which is prone to failure and creates more space.)

Took my 2021 JLUR 3.6e out in the trail for the first time today after having a new JE Reel front driveshaft installed.

The double cardon is hitting the transmission heater. It’s leaking transmission and coolant now.

Has anyone else had this issue and what did you do to fix it?

@mgroeger Didn't you have an issue with this, as well?

I would just grind that down to make clearance. Make sure to grind both sides, of course.

Engineering quote of the day - "Clearance is clearance."

Is that a 1350 joint or a 1310? If it’s the latter maybe going to the smaller 1310 would be a better option.

I have not personally compared the two sizes side by side as I run a Metalcloak front and rear which use the 1310 U-joints. I know the one ton axles typically run 1350 U-joints which I believe are more stout. My Jeep is a 2.0 but they are similar underneath. My CV joint measures 12.5” around.

looks like the double cardon sits closer to the transfer case too because yours uses a different style yoke.

I think this is a design flaw. Here’s some pics of JE Reels yoke.

Yours are definitely larger than mine, but not that much larger. I wonder if you received a JK drive shaft instead of a JL one. Have you confirmed the part numbers?

Have not had a chance to confirm part numbers. I was able to make contact with someone from JE Reel and will hear back from the manager on Monday.

I went to check my Adams 1350 since you brought it up. Its close, but the shaft side of the Cardon sits a tad back from the cooler on mine.

Thanks for checking that out. That’s what I’m seeing from other driveshaft companies.

Will be interesting to see what JE Reel says. I was just trying to mitigate my rear drive shaft from hitting my Artec fuel tank skid plate. I recently replaced the factory rear one with a Metalcloak one because it’s thinner. It still hit. I spoke to Artec who told me Jeep changed the fuel tank design in 2019 because of contact issues. I said my Jeep is a 2021. He told me they didn’t catch the design change until late 2021 so there is nothing they can do. He did offer to replace it at a cost of $700.00. I will now have to modify it myself. I won’t be surprised if JE reel says something similar. Good luck.

I was going to go with JE Reel. I ended up with the Adams 1350 front and rear. No problems in the front but rubbing on the rear shaft along the E-Torq battery skid. A minor fab work and seems to have fixed it. Adam's response was to move axle over a bit. :LOL:
