You should have recommendations by the manufacturer about items that should be addressed at the high mileage interval. Most dealerships will offer free inspections and you can always retrieve additional opinions on items to be addressed according to the condition of your vehicle.
It*s a good idea to check your owner's manual for the maintenance schedule. If you do not have the owner*s manual, you may be able to find it online or check at your local dealership for what they recommend.
