when i am on uneven rode or rode with alot of pots hole the rear end acts crazy. is it safe for me to assume that a trailing arm is bent? or should i get and alinement? i just bought the car and it didnt do this on the test drive but it wasnt raining then and it has been now. i also put new tires on it idk if that plays a part. is the trailing arm from the w body store a good upgrade? is that a plug and play deal? thanks guys sorry for any typeo on my iphone
