Say a truck goes into a dealership for a front axle pinion seal repair. And then upon being picked up after the work was done the front differential grenades and seizes up about 1.5 miles down the road. After being towed back to the dealership they diagnosed the issue as the pinion bearing failing.
What are the odds that the bearing was bad all along and chose that moment to fail? Or is it more likely due to the seal replacement procedure having something to do with it?
