Power Train Components 63046 Spindle Wheel Hub Replacement

The Power Train Components (PTC) 63046 is a replacement spindle wheel hub designed to restore proper OE fit, form, and function on late-model import vehicles. Unlike unitized hub bearing assemblies, this spindle hub is a press-in component that works in conjunction with a separate wheel bearing, making it the correct solution when a seized bearing race has scored or damaged the original spindle hub shaft.

Why Replace the Spindle Hub?

On many late-model import applications, the wheel bearing's inner race can seize onto the spindle hub during removal, scoring the hub shaft and making it impossible to reuse. Installing a new bearing onto a damaged spindle hub will compromise bearing performance and longevity. Replacing the spindle hub at the same time as the bearing ensures the new bearing seats properly and performs to OE standards.

Key Features:

• OE-matched design — engineered to match original equipment fit, form, and function
• Dimensional end testing — verified to ensure end play meets OE specifications, a critical factor in controlling noise and vibration
• Metallurgy testing — material quality is tested to eliminate metal fatigue and premature failure
• No moving parts — the spindle hub itself contains no moving parts; wheel bearing is sold separately
• High-quality materials — built to OE-level standards for long-term durability and reliable performance

The PTC 63046 spindle hub is part of Power Train Components' comprehensive hub assembly lineup, engineered for professional-grade replacement results. Always replace the spindle hub together with the wheel bearing for a complete, properly performing repair.
