It is my opinion that all car manufactures have intentionally left grease certs out to make the front end wear out sooner so you will want to buy a new vehicle. I bought a shot needle that hooks on to the grease gun hose tip. With the needle you can stick it thru the rubber and add grease. About once every 10,000 miles is good unless you drive on a lot of wet roads. Any autoparts store stocks the needle accessory
