Overview

The Genuine Subaru OEM Axle Snap-ring (Part #28035TA040) is a factory-original transmission-side retaining ring designed for the Subaru WRX. This precision-engineered circlip secures the axle shaft within the transmission housing, ensuring proper axle retention and preventing lateral movement under hard acceleration and cornering loads. If you're rebuilding your WRX drivetrain or replacing a worn or broken snap-ring, this is the exact part Subaru installs at the factory — no guesswork, no fitment risk.

Key Features & Benefits

• Genuine Subaru OEM Quality — Manufactured to Subaru's exact factory specifications, ensuring a precise fit and long-term reliability that aftermarket alternatives can't guarantee.
• Critical Retention Function — Secures the CV axle shaft firmly in the transmission, preventing axle walkout that can cause drivetrain damage, vibration, or complete axle disengagement.
• Factory Warranty Backed — As a genuine Subaru part, it is covered under Subaru's OEM parts warranty when purchased through an authorized dealer.
• Essential Rebuild Component — A required replacement item during any axle shaft R&R, transmission rebuild, or differential service on the affected vehicles.

Installation

This snap-ring is installed at the transmission-side inboard joint of the CV axle shaft. Replacement requires removal of the axle shaft from the transmission. A proper snap-ring plier set is required for safe removal and installation of the circlip. Because incorrect installation of a snap-ring can result in axle walkout and serious drivetrain damage, professional installation by a qualified Subaru technician is strongly recommended. Always inspect the snap-ring groove for wear or damage before reinstalling a new ring.
