ACDelco 19404634 GM OE Rear Axle Shaft Gasket

The ACDelco 19404634 is a GM Original Equipment rear axle shaft gasket designed to provide a precise, leak-free seal at the rear axle shaft flange. Engineered to OEM specifications, this gasket replaces the factory component with a part that matches the original in fit, form, and function — ensuring reliable sealing performance and long service life.

As a GM OE part, this gasket is manufactured to the exacting standards set by General Motors and is the same type of component used during original vehicle assembly. It is ideal for use during axle shaft removal, bearing replacement, or any rear differential service where the original gasket has been disturbed or damaged.

Key Features:

• GM Original Equipment rear axle shaft gasket
• Manufactured to GM OE specifications for precise fit and function
• Provides a reliable, leak-free seal at the rear axle shaft flange
• Helps prevent gear oil or differential fluid leaks
• Direct OEM replacement — no modification required
• Backed by ACDelco and General Motors quality standards

Replace this gasket any time the rear axle shaft is removed to ensure a proper reseal of the axle assembly and protect against fluid leaks that could lead to premature wear or differential damage.
