The Chronicles of JeepFan and GemHunter

Looks great!
Just curious. What didn’t you like about the Wild Peaks? Or is it just the size…. 😉


As I hate the BFG’s. I like the 35’s more than the 32’s but the wild peaks just seemed to drive much better especially in wet or icy conditions.

Thanks for the question—I’m sure others are curious about this too. Just to clarify, I actually like the Wildpeak tires. I thought the Gladiator rode well with them, and honestly, I didn’t have any issues at all. That said, I prefer the look of the Gladiator with the black Mopar wheels and BFG tires, and I think the ride feels a bit softer with the BFGs. Both sets of tires are Load Range C, so the difference is probably just in my head—LOL!

Here's a breakdown of the 2 tires...

Original: Falcon Wildpeak AT3W 285/70/R17 - 11.22" Wide, 32.7" High
NEW: BFG KO2s 315/70/R17 - 12.4" Wide, 34.36" High

We took my Falken Wildpeaks and wheels off my Rubicon JT and threw them on my wife's JLU and she loves them. I also thought they rode well in most conditions but moved to 35's for a more aggressive tire as my JT sees much more off road than hers does. I agree with you on the look of those wheels with the BFG's. Nice combo.
 
Our humming 2023 JLUR with a 3.5" Rancho lift and 1350 front and rear driveshafts. (The rear shaft was custom built with an OE-style pinion flange.)

I had a low-frequency humming noise start right after installing the lift. It came on around 65 mph and faded out by 80. Didn’t matter if I was in gear or coasting. It was always there and driving me crazy.

I swapped tires, checked alignment, corrected the pinion angle (was about 3° off, now close to 0°), and even had my 1350 double cardan rear shaft rebuilt and balanced. But the hum stayed. However, with the rear driveshaft removed and driving in 4WD, the noise was completely gone!

Just for kicks, today I reinstalled the stock factory rear driveshaft and the noise disappeared. Completely.

After chasing this for months, it turns out (I think) the aftermarket shaft just didn’t agree with my Jeep. Probably a harmonic issue or the OE style flange not playing nice even though it was freshly rebuilt and balanced. The stock shaft is smooth as glass.

Lesson: If you're dealing with a mystery noise after a lift, try going back to the stock driveshaft even if it’s not ideal long-term for lifted JL, it might help you isolate the issue.

Hope this saves someone else a few headaches.

Big thank you to Eddie for his advice and help tracking down this issue. As for me; no more sleepless nights thinking about this issue! I'll just have to keep an eye on the rzeppa cv boot! (y)

Glad you got it figured out, but dang, it’s a bummer that you had to remove that driveshaft.

Totally nuts that going back to the OE shaft, the one that got you going down this rabbit hole, ultimately was what got rid of the hum. Not that it should have made a difference or enough of one to be a problem but I do have to wonder if your pinion being off a bit caused the OE shaft to make the noise. After we fixed that at my place, going back to OE must have fixed things completely.

I do have to also wonder if you change the pinion flange to a standard yoke if that would help with your new double cardan shaft.

Can't wait to hit the trails with you again and now with a quite Jeep!
