What does the differential pinion spacer do?

The pinion spacer (also called a collapsible or crush spacer in some applications) sits between the front and rear pinion bearings. It sets the correct bearing preload on the pinion shaft — a critical tolerance for differential durability, quiet operation, and gear mesh accuracy.

Why use a genuine Toyota part rather than aftermarket?

Differential pinion spacers must meet precise dimensional tolerances. Genuine Toyota parts are manufactured to OEM specification and ensure correct preload is achievable. Using a non-OEM spacer risks incorrect preload, leading to bearing noise, premature failure, or differential damage.

When should the pinion spacer be replaced?

The pinion spacer should be replaced any time the pinion nut is removed and the differential is disassembled — once collapsed or disturbed, a spacer cannot reliably re-set the correct preload. It is standard practice to fit a new spacer during any differential rebuild.

Does this fit the Hilux Surf (4Runner) as well as the Hilux Pickup?

Yes. This part number 41231-22010 is also confirmed for Toyota Hilux Surf (4Runner) models sharing the same front differential assembly — including KZN130, VZN130, KZN185, RZN185, and VZN185 variants. See the full compatibility list above.
