Had 5:13's Installed Recently. Anyone else have a noise in the rear?
I recently had 5:13's installed and have a 2011 JK Automatic on 35's. I noticed on high speeds when decelerating I hear almost a whining noise coming from the rear and sometimes at slower speeds when decelerating. Curious if this was common.

Did you replace the bearings? It sounds like the gears may not be set up right, or maybe an issue with the bearings or bearing pre load. I have heard gears whine and still last a long time, but I would take it back to whoever installed them and let them check it out.

What is this whirring noise?
Whirring noise only while decelerating at any or all speeds is most likely caused by bad pinion bearings or loose pinion bearing preload, and almost never by bad ring and pinion gears.
A howl or whine during acceleration over a small or large speed range is usually caused by worn ring and pinion gears or improper gear set up.
Rumbling or whirring at speeds over about 20 mph can be caused by worn carrier bearings. The noise may change while turning.
Regular clunking every few feet may indicate broken ring or pinion gears.
Banging or clunking only on corners can be caused by broken spider gears, lack of sufficient positraction lubrication, or worn positraction clutches.
Rumble while turning may indicate bad wheel bearings.
A steady vibration that increases with the vehicle’s speed can be caused by worn u-joints or an out of balance driveshaft.
Clunking only when starting to move or getting on and off the gas might be loose yokes, bad u-joints or worn transfer case or transmission parts.
