Whining grinding sound when going forward.
His morning when I left to go to work I noticed a sound that almost sounded like a wheel bearing failing.metal on metal grinding/ whining sound. Stops at park and neutral positions and also make no sound at all in reverse, just forward. I inspected the brakes and saw nothing abnormal.
I was using the 4 wheel drive the last time I was driving. Honestly it was the first time I used the 4 wheel drive in a year. I reversed it a couple of times thinking maybe it was completely disengaged
It's a 2015 JK unlimited with 4:10 gears and automatic transmission
TIA for any advise

You said you inspected the brakes? It's not one of the squealers from the pads? Does it go away when you hit the brakes?

It doesn't stop when I press the brakes. It's odd only going forward. I think it might have to do with me shifting out 4wheel drive while parked in the driveway. Don't know.

remove tire, then two bolts holding caliper on, clean just brake pads and not slider with brake cleaner, clean rotors with brake clear. Then put back together and see if still makes noise. It could be a loose caliper bolt, maybe allowing enough movement forward to contact something and not going backwards? my $.01

Sadly it wasn't the brakes or a caliper. Anything loose. It makes the noise in gear, neutral, with the brake pedal pushed, or not pushed.
I spoke with the mechanic how did the gears and he thinks it's the spider gears in the new front carrier we bought when going from 3:21 to 4:10. It only has about 200 miles on it since installation.
Should have the word soon.

That pinion nut came loose because it was installed wrong. The pinion nut is generally a one-time use nut unless you use lock-tite.
I would keep a close eye on everything if the half-a$$ed the pinion nut.
