Hello, I have 2014 Silverado 4x4. It has the "snow plow prep package"
I do not have a plow however. Going over rough roads,potholes,or large
expansion joints the rear end seems to want to move side to side,at least
it feels like that. The front end feels real good either over bumps or curves.
The rear will feel like the side to side movement when on a turn and
going over bumps.
Everything seems good in the back suspension. This truck has only 9112
miles.
Any thoughts?
