Description
For van applications, GM introduced the Express and Savana in 1996 as the successors to the Vandura line, equipping them with full-floating rear axles for improved durability and towing capacity, along with a spindle system that simplified maintenance. Unlike the multi-piece bearing retention setup found in earlier GMC pickups, these vans use a single spindle nut with a solid key and retainer ring for greater reliability and longer service life. Owners of GMC 2500/3500 pickups or Express/Savana vans who notice steering instability, uneven tire wear, or alignment issues can benefit from a straightforward replacement that restores safety and handling.
Spindles are central to the suspension system. They support the wheel hubs, bearings, and drivetrain assemblies while ensuring proper weight distribution and precise steering control. Replacing a worn spindle at the first signs of trouble helps maintain safe operation and prolongs the life of your vehicle.
Keep your GMC 2500 and 3500 pickup, Chevrolet Express, or GMC Savana in dependable service with our heavy-duty, direct-fit spindles.
