Sliding, scrambling, and skidding across the frozen tundra is no big deal for your rough and tumble truck. In a word, your rig's ability to handle absolutely any surface you encounter is cool. Boost your ride's performance in all temperatures and terrains—and make sure the only thing your ride slips on is ice, not oil—by upgrading your differential pinion seal.

Keep Your Bearings
When your pinion seal fails, it spells lights out for your rig's differential bearings and gears. If you notice your pinion seal is leaking, your differential is low on fluid, or your vehicle is whining more than your teenage nephew Jayden when it's in motion, your pinion seal may be done for. The good news is, if you act fast, you can fix and prevent substantial damage to your ride. As soon as your seal starts to falter, give it the heave-ho and replace it with a new differential pinion seal from 4 Wheel Parts. We carry a wide variety of pinion seals to fit a barrage of axles, including the Spicer 44895 rear pinion oil seal and Crown Automotive's front axle pinion seal (5066053AA), inner small pinion seal (5072265AA), and rear axle outer flanged pinion seal (5072473AA). Keep the oil in, and keep the water, dirt, and other debris out.
