Temporary rumble after replacing belt related items
So the other day I was at a buddies house where we replaced a potentially faulty belt tensioner and idler pulley.
I decided to replace the belt too since it had to come off anyway.
Anyway all went well and I took her for a spin on the freeway. On the way there (cruising around a steady 40mph) everything seemed fine...nothing out of the ordinary. Well, shortly after hitting the freeway and and accelerating to about 70mph I suddenly noticed the vehicle began to kind of rumble/shake and it seemed to lose power ever so slightly.
I decided to pull into the breakdown lane and inspect things. First thing I noticed was a sort of rubber-burning smell especially evident around the rear-right wheel. I looked around and didn't notice anything intruding (buddy told me a plastic bag might have gotten caught in one of the rear tires).
Anyway I got back in the car and started driving home and to my surprise the rumbling had ceased and the car was driving fine just like it should.
I haven't experienced this issue since...which is making me wonder what caused it in the first place.
Any ideas?

Hey torake. Yeah I'm pretty sure all tools were accounted for. Guess something could have got loose and lodged in the rear wheel mechanism...although there still is a slight hint of rubber-burning smell in that area. Gonna keep an eye on it.
