Inspect all belts for wear and tear and replace any that have become worn out. Make sure all hoses are secure with no broken clamps that could cause them to come loose over time. Ensure all accessories are properly tightened with no rattles coming from them when driving or starting up the vehicle. Check all interior cabin parts for anything that may have become loose over time and re-secure them if necessary. Lastly check shocks absorbers and suspension components for signs of wear-and-tear which could cause additional rattles on acceleration or bumps in roads.
