Do you have a manual transmission? If so a top gear relearn may be required.

I have the 8 speed auto. My Jeep is 100% stock. I’m afraid of modifying it.

I’m in the Bay Area, so there is a shelter in place order due to the virus for the next few weeks. But, Auto repair is considered an essential job at the moment.

SHTF and the Jeep is in the shop.

Good news, they replaced the left rear axle due to a loose tone ring.
