Vanagon Front Lower Ball Joint – 251-407-187 The 251-407-187 is the correct lower ball joint for all Volkswagen Vanagons produced between 1980 and 1991. Because the Vanagon is a heavy vehicle—especially Westfalia campers—the lower ball joints endure immense stress during cornering and braking. Replacing worn units is the most effective way to eliminate front-end play and restore highway stability. These joints are typically maintenance-free and sealed with high-grade elastomer boots to keep out road salt and grime. Using a premium-quality replacement ensures that your suspension can handle the rigors of both daily driving and off-road excursions in Syncro models.
