****** Edited for clarity and updated specifics. I realized at 4 am I had mistyped and misspoken on several things******
So my 2018 JL sport has this noise at super slow speeds. I do have the Dana 44 with the anti spin set-up. Vehicle only has 83 miles on it and I stopped by the dealer after reading the other rear diff noise thread on here. They made me an appointment to bring it in next week and get it listened/looked at. But while I was at the dealership I decided to ask my super cool salesman about driving a few other new on the lot vehicles to see if same noise was heard. Well low and behold I had the opportunity to drive 11 new Jeeps. One of which was a 2020 Sahara that had just been pulled off the transport truck. Here’s the specific list of what was driven.
1. 2019 JL Sport S with base rear axle non 44 and 2.0 engine. (No rear noise)
2. 2020 JL Sport 2.0 all base stock axles non 44 and 3.6 engine. (No rear noise)
3. 2018 Jeep Sahara JLU with tow package and 44 and axle w/anti spin and 2.0 engine. (Yes in rear noise)
4. 2019 Rubicon JL, 2.0 engine. (Yes on rear noise)
5. 2019 JL Sport non S With tow package and Dana 44 rear and anti spin and the 3.6 engine. ( yes on rear noise)
6. 2018 JLU Rubicon Dana 44 front and rear. 3.6 engine. (Yes on rear noise)
7. 2018 JLU Rubicon Dana 44 front and rear w/ 2.0 eng. (Yes on rear noise)
8. 2020 JL Rubicon with Dana 44’s and 2.0 engine. (Yes on rear noise)
9. 2019 JLU Sahara with base axles non 44 rear w/2.0 engine. (No noise)
10. 2020 Sport base model non 44 rear and the 2.0 engine. (No noise)
11. 2020 JLU 2 with the obvious 44 axles and the 3.6. (yes on rear noise)
All vehicles had under 200 miles each and all were driven for 5 miles same route each time. All vehicles with the Dana 44 repeat had the slow rear rotational noise from rear axles. So we are either looking at something that is specific to JL’s or we’re looking at a future major recall from Chrysler. I had three different managers and one tech eventually ride along and listen and everyone was like, what the heck... we’ve never heard that before.
My personal 2018 Sport with the Dana 44 rear antispin/axle is an awesome vehicle and has no problems outside of the rear noise and it drives like a dream in 2H-4H and 4L. If this turns into an issue where I have to leave it for multiple weeks while parts are ordered and it’s repaired, like a new axle. I guarantee you I will lay the keys on the salesman’s desk and walk out and never buy another Jeep again. I am an Emergency Rescue first responder for the County and I have to have my vehicle in tip top shape 24-7 where we live and work and this situation will not be acceptable. Three of or guys on our west end team have new JL’s that were all recently purchased in the last 3 months, and we plan on turning them once again into high water rescue vehicles. We unfortunately go through vehicles every three years doing what we do and we can not be down one man at any particular time.
So my curiosity is, do we really have a major situation coming to thousands and thousands of JL owners or is this actually just a noise that has no real problem associated with it.
