Chevrolet Trailblazer Differential Seal

The Chevrolet Trailblazer Differential Seal ensures that gear oil remains inside the axle housing and dirt is prevented from entering. It also ensures that torque flows smoothly through the axle during every drive. Surrounding the axle shaft, the Differential Seal is a round rubber and synthetic seal that traps 75W-90 lubricant. This allows the internal differential gears to turn freely and prevents them from leaking out and starving. While it is still in a state of integrity, it also protects the function from water and road grit that can wreak havoc on the gears. In either case, the Differential Seal is a simple yet essential part. The Chevrolet SUV has been relying on two principal differential designs over time, which are the open unit and the limited slip unit, with the seal supporting both by retaining their shared lubricant bath. The open design distributes power equally, which can allow a wheel to spin on slippery road surfaces. In contrast, the limited slip employs clutches and springs to redirect additional torque to the wheel with traction. Thus, this process ensures the Trailblazer has better control in corners and loose ground. Since every Chevrolet axle depends on the seal to trap lubricant, the replacement of the Differential Seal should take place quickly, cracks, or is pried loose during axle work. Otherwise, the Trailblazer will suffer from noisy, overheated gears, which will lead to costly repairs. Additionally, the fresh Differential Seal must sit flush with the bore to do its job.

Each OEM Chevrolet Trailblazer Differential Seal we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
