Serpentine belt spin motion
Alright Gents, is it normal for the serpentine belt to have ever so slight “wobble” alike motion to it when it’s spinning?
When the engine is running I noticed ever so slight a lateral motion to it when it spins. I was under the impression it’d spin in laser perfect rotational motion. Was rather curious if this is a normal occurrence.
the belt is sitting on all the grooves correctly and related components have less than 10k miles on them. No squeak or any noise. Just a ever so slight visual side to side, lateral, a “wobble” motion when you stand there and stare at the belt’s spinning motion.
