Sideways Sliding on Potholes and Bumps

Has anyone else experienced their Jimny jumping and sliding sideways (rear wheels) when encountering potholes or bumps? I’ve been using mine for the past 7 months, but I’ve only noticed this issue in the last month. Could it be due to changes in my driving style over time? I’m curious to hear others’ experiences and thoughts on this matter. Additionally, should I visit the service center to check if any suspension-related components are loose?"
