Eurospare 12456ES Differential Pinion Bearing Spacer Crush Sleeve

The Eurospare 12456ES is a differential pinion bearing spacer, also commonly referred to as a differential crush sleeve or collapsible spacer. This precision-engineered component sits between the inner and outer pinion bearings inside the differential housing and is designed to collapse under a specific load to establish the correct pinion bearing preload during assembly.

Replacing the crush sleeve is a required step any time the pinion nut is removed — including during a pinion seal replacement or differential rebuild. Reusing the original sleeve can result in improper bearing preload, which leads to premature bearing wear, differential noise, and potential gear damage.

Key Features:

• Direct-fit replacement differential pinion bearing spacer
• Establishes correct pinion bearing preload when properly torqued
• Must be replaced any time the pinion nut is removed
• Manufactured to meet or exceed OEM specifications
• Supplied as a single crush sleeve
