I hear a rattle in the rear passenger's side by the strut bar.
Hi there. If you are hearing a rattle from the rear passenger side of the vehicle, then there may be a problem with the suspension. Rattling noises can often be caused by blown shocks, or worn/damaged suspension components, such as bushing or joints. I would recommend having the vehicle driven, and the suspension inspected, by a professional technician, such as one from YourMechanic.
