High-strength A-Premium front CV axle shaft assembly engineered as a direct-fit replacement for compatible Subaru Tribeca, Legacy H6 3.6L and Outback (CVT) models on either the driver or passenger side.

This replacement constant-velocity (CV) axle from A-Premium is built to restore driveline power transfer and steering articulation for select Subaru vehicles. It arrives as a complete axle assembly with the external boot, axle nut and manufacturer-referenced fitment numbers, designed to simplify swap-outs and reduce downtime compared with rebuilding an old axle. Specifications such as spline counts, compressed length and spindle thread details are matched to original-equipment dimensions to ensure smooth installation and reliable operation when fitted to the correct model years and transmission type.

What technical specs should I verify before buying?

Confirming a few key measurements prevents incorrect fitment and saves time during installation. Important details include the axle’s compressed length, spline counts and the spindle nut thread size, all of which must match your vehicle’s hub and transmission mating surfaces. This assembly includes the external neoprene outboard boot and the axle nut for a more complete replacement.

• Compressed length: 32.52 inches to match OEM geometry

How will this axle assembly affect drivability and installation?

Replacing a worn CV axle restores smooth torque delivery to the front wheels and helps eliminate clicking, vibration or grease leakage caused by torn boots or failing joints. The assembly ships pre-assembled with the outboard neoprene boot, which streamlines installation compared with sourcing multiple parts separately. Proper installation by a qualified technician or a knowledgeable DIYer will reestablish correct wheel alignment of driveline components.

• Restores power transfer from transmission to wheel under steering angles
• Supplied with neoprene outboard boot to reduce contamination risk
• Axle nut included for a more complete replacement kit
• No ABS ring supplied — ensure hub compatibility beforehand

It’s suitable for professional mechanics replacing a failed axle and for experienced DIYers who can verify spline counts, length and thread size prior to installation.
