Why does your mk4 astra have a back end sway?

Back end sway in a Mk4 Astra can be attributed to several factors, including worn or damaged suspension components, such as bushings or shocks, which can lead to instability during cornering. Additionally, improper tire pressure or alignment issues may contribute to handling problems. Lastly, if the vehicle is carrying uneven weight or has a heavier load in the rear, it can exacerbate the sway. Regular maintenance and inspections can help identify and rectify these issues.
