I just installed some new suspension stuff on my 2017 JKUR. One front and one rear factory shocks were leaking oil at 24K milesI bought a 2018 JKUR Recon edition with 2222 miles on it. At 6000 miles I had the same thing, figured it was because I didn't rotate the tires. Went to discount tire to rotate. The guy said it could be the shocks, I couldn't believe this because they were almost new. He talked me out of rotating them saying the vibration would be terrible, big mistake. He was right about the shocks though. I installed a Teraflex leveling kit and new Rancho 5000XL adjustable shocks, then rotated the tires. No vibration and it didn't take very long for the tires to even out when moved to the back. I have 12000 on the jeep now and the tires that moved from the back to the front have no cupping at all and the cupped tires on the back are normal. So in my case, the OME Rubicon shocks were not worth a crap with only a few thousand miles on them.
