Complete Installation Tutorial

Preparation Steps

Safely lift vehicle and remove wheel. Remove brake caliper and secure with wire. Remove brake rotor and cotter pin from old axle nut. Clean axle threads thoroughly.

Thread new axle nut onto clean axle shaft by hand first. Use appropriate socket and torque wrench to tighten to manufacturer specifications (typically 140-180 ft-lbs).

Final Assembly

Install new cotter pin through axle nut slots. Reassemble brake components in reverse order. Check wheel bearing play and road test for proper operation.

Technical Questions & Expert Solutions

Consult your Subaru service manual for exact specifications. Most models require 140-180 ft-lbs, but always verify for your specific year and model.

How do I know if my axle nut needs replacement?

Signs include loose wheel bearings, clicking noises during turns, excessive wheel play, or visible thread damage on the existing nut.

Is professional installation recommended?

While DIY-friendly for experienced mechanics, proper torque specifications and safety procedures make professional installation advisable for most owners.
