Slight vibration

[Ram4u]

Pop the hood, start your engine, look down to pulley at the bottom far left. All my belt pulleys are very true with no wobble except the Harmonic Balancer (Crankshaft Damper). Here is link to part 53022083AA - Genuine Mopar DAMPER-CRANKSHAFT . Here is a link to video I took, not the greatest but maybe will help. Lance shared 1 video with you .

What year Ram and engine do you have?...Replacing mine on 2019 Ram 5.7 Hemi Gas

When my truck was new I had a vibration I could feel in the steering wheel and see on my passenger seat if I looked over there while vibrating. The dealer road force balanced and then discovered I had 2 defective tires. They replaced them and re road force balanced and I could go all the way to 90 mph smooth as silk.
