wrangler Sahara slight roughness

[BrianBe]

2014 Sahara with 3" lift experiences slight roughness while coasting or low power settings. Doesn't occur during acceleration. No noticeable RPM change and also not happening while transmission is shifting. Wondering if it's some kind of mechanical chatter from the lift altering the steering and transmission geometry? Anyone experiencing this? Thanks.

Stock control arms? If so I suspect its a driveshaft issue.

Welcome to JO Brian!  x2 on the driveshaft. I haven't experienced it with a Jeep but had something akin to it in a Samurai. Steep driveshaft angles meant weird vibes under light throttle. On throttle = fine. Off throttle = fine. Is your front ujoint pretty much straight??

Oh, dumb question and oversight on my part: have you checked the rzeppa joints??
