The same thing happened to me. I have a 19 trail boss and installed the Moto fab 1.5” front lift. The ball joint on the right front upper control arm broke after about 15,000 miles. I replaced it and kept the lift on and about a month later the left side ball joint broke. So I removed the moto fab lift. Good thing both times it broke I was going slow I would hate to have it happen on the road.

I have a 14 GMC Sierra 4x4 and it sounds like I am having the same issue. It sounds like I’m driving over rumble strips on the road. It usually lasts for 2 - 3 seconds and it then it goes away. Then the noise will return in another 10 or 15 seconds. It seems like it does it the most just cruising when light on the throttle. The RPMs do the same shutter too. The tach will bounce 100 RPMs up and down.
