How do I install the LubeLocker 9.25" differential cover gasket?

Installation is straightforward: drain differential fluid, clean mating surfaces, lay the gasket into position, and torque the cover bolts to factory specs. The gasket’s flexibility helps line up bolt holes and reduces the chance of pinching during assembly.

• Drain fluid and clean old gasket residue thoroughly
• Place gasket on clean flange, align all bolt holes
• Tighten bolts in a crisscross pattern to recommended torque
• Refill differential with the correct lubricant after installation

What materials and properties does this gasket offer?

The LubeLocker gasket is made from a durable elastomer designed to resist oil swelling, heat, and common workshop chemicals. It maintains a consistent seal under moderate thermal cycling and vibration typical of vehicle differentials.

• Oil- and solvent-resistant elastomer construction
• Flexible for easier alignment and installation
• Resists compression set to preserve sealing over time
• Designed to withstand typical differential operating temperatures

Can I reuse this gasket or should it be replaced every time?

While some gaskets can be reused, the best practice is to install a new gasket whenever the cover is removed to ensure a reliable seal and avoid slow leaks. A fresh LubeLocker gasket helps eliminate uncertainty after service or repairs.

• Recommended replacement each time the cover is removed
• New gasket reduces risk of leaks and future downtime
• Cost-effective insurance against seepage and contamination
• Simple replacement during routine differential service
