On our way home with the new trailer, the highway driving was really smooth, but when we got to the city, I had some really unsettling bucking on a not-so-great stretch of road leading into the city. I could feel the trailer pulling back and pushing forward on the car as we went over some bumps - but it was almost as if we were getting into a resonant frequency where it would buck a bunch of times in a row.
The trailer is gutted so should be fairly
light. The previous owner put new tires/wheels/bearings.
I have towed my utility trailer all over town without such unsettling bucking. WHen empty, it just bounces over bumps and when full I can feel the
weight but I never feel like the trailer is driving the car. Any tips for troubleshooting? I'd like to start with the easiest checks and move on from there :-)
Thanks!
