Hi all,


I've got a 2020 Jeep Gladiator Sport with about 130,000 miles on it.

A few weeks ago I was driving in a snow storm in 4WD. I got home, disengaged 4WD and pulled straight into my garage. The next day, and since then, I've had a strange clicking noise coming from my front passenger wheel. I can hear this click/clunk noise while driving. When I jack the wheel off the ground I can still hear it clunk while rotating the wheel by hand. I checked the FAD and it seems to be operating fine. When I engage 4WD the clunking goes away completely both on ground and jacked into the air. I can only hear the clunk when the wheels are spinning in 2WD.

Any thoughts? U joint maybe?


Also, the other day my start/stop system warning light came on when driving up a hill, and my CEL came on when I stopped at the top of the hill with the following codes -
P0300
P0171
P0300
P2096
P0137
P0128


Not quite sure where to start with this but I have a feeling these codes might be due to the aux battery going bad. I still have the original aux and main battery and a friend of mines JL had some strange electrical gremlins when his aux battery started going bad. I replaced the plugs and coils about 30,000 miles ago and these codes have been very intermittent. I've cleared them and driven normally for a few days then they randomly come back on.


Happy to post videos of the noise from the wheel well but hoping to see if this is a common issue for failing batteries and thoughts on the passenger wheel noises. Thank you!

I think the batteries might be a good place to start, if they are original. I am not sure about the other though…

An engine code could disable ESS. Fix the misfire code first then work on the other codes. Address ESS and battery talk later, if you even have to.

Bad batteries gave me a phantom misfire code

Hmmm If your batteries were bad enough to cause a misfire either erroneous or not, you would have other symptoms as well. Ess battery charging message or Auxiliary switches inop.

I also had a bunch of codes. I don’t remember them all. It was on my first gladiator.
