Hearing a driveline vibration or clunk under your vehicle? The center bearing support might be worn. This Febest part (OPCB-ANT) replaces OEM numbers 20781756 and 446073. It's the rubber-mounted bracket that supports the middle of a two-piece driveshaft, reducing vibration and allowing proper alignment. Made with high-quality synthetic rubber that lasts longer and handles heat better than cheap alternatives. Febest uses German engineering standards and includes a 1-year warranty. Replacing a worn center bearing can eliminate shakes, noises, and driveline stress. Installation requires supporting the driveshaft and removing the old bracket. A critical component for smooth driving in many trucks, vans, and SUVs. Restore your ride's smoothness with a durable replacement.
