Vibration... HELP

[Blake aus]

Hi Guys,
I own a 2021 Laramie with 25,000 miles, it has 2-3 inch lift fox 2.5s and 35inch tyres. It has developed a strange vibration mainly noticeable around the 30 to 40MPH mark, almost feel as if it is pulsing slightly back and forth. has anybody else experienced this?
Thanks
Blake

What tires are you using? Have you checked the torque on lug nuts recently?

Maybe rebalance the tires and rotate them

Wheelbalance or ball joint one or the other
