I did the ball joints, too, with no luck.
Hopefully the dealer gets back to me soon... they are having some "difficulty" answering the phone today (called 5 times over the course of 5 hours, finally left a voice mail...).
Thanks!
Ok, that's one I had not heard! Just to be clear, you're talking about the "big" nut at the end of the axle spline at the hub? Do you torque to 175?
I have the HF version of that same light... $5.

I use it all the time, and have dropped it on the garage floor many times and it still works. The only thing the HF version is missing is the red.
Mine's not a vibration, mine is a creaking/clicking coming from (as far as I can tell) the TC area, rear driveshaft. It's not a suspension noise: I can hop up and down on the tailgate all day and it doesn't make a sound, but driving slow, like turning into a parking spot, or my garage and the...
most likely... usually using the O2 sensor readings is to help diagnose something else in the air/fuel chain of events (pumps, throttle, intake, vacuum leak, etc). It's pretty rare you'll find a bad O2 sensor with a scanner that the PCM hasn't already picked up.
But, you can hook up JScan and...
Nope, at idle (after the coolant warms up) you should also see the fluctuation.
And if the voltage is out of range, you'll get a CEL. And, if it doesn't move at all (stays constant) you should also get a CEL.
Yes, we have 4... ignore the downstream, they have no bearing on A:F trims. They are used only to gauge cat efficiency. In fact, their behavior is not even the same as the upstream - they will peg rich once the cat's are heated up and not cycle like the upstream O2 sensors.
Got it!
So, please don't take this the wrong way: based on your original question, I'm guessing you have not done this before? For the moment, I'll assume you haven't.
It's not as simple as measuring the voltage (it's not constant). There is a switch from low -> high -> low, like a sound...
FWIW, I had this package on my 2018 JL and it made zero difference. Using the BT speakerphone while driving at anything over 35 MPH sounded like I was standing next to a waterfall from the other end. ANC did nothing...
I ended up buying a blue parrot BT headset made for "industrial"...
I get slightly better "city" MPG if I drive anywhere over about 72 MPH on the highway. As speed increases from there (for me) my MPGs suffer mightily. It's the fantastic aerodynamics of the JT (and I have a stubby bumper)
Just be careful what you mount there. The factory airbag deploys around the grab bar (deploys above, but the bag goes up toward the dash and down toward the passenger's legs) and will launch anything in the way into the passenger. It could also launch something, like a CB mic, at the driver.
I...
