Replacement Air Cooled 1968 Bay Window Bus Windshield Wiper Arms, fits right hand and left hand side. This is a one yearn only windshield wiper arm. We strongly suggest checking windshield wiper pivot shafts any time wiper arms are replaced. Faulty pivot shafts can cause serious problems and could result in scratching a windshield.
Most wiper pivot shafts fail due to age, seal damage and lack of lubrication. Factory specs recommends lubrication every 90 days.
Tech Tip: Wiper shaft lubrication is accomplished by removing the wiper arm, gently removing the plastic seal, and applying a few drops of oil where the shaft protrudes from the brass barrel. Switching on the wiper motor with the arms still removed, and applying a few more drops will ensure full and proper oil penetration.
