Whiteline Rear Toe Arm Inner Bushing Kit Subaru WRX 08-26 / STI 08-21 | W63583

Upgrade your rear suspension and restore precise alignment control with the Whiteline Rear Toe Arm Inner Bushing Kit (W63583). This direct‑fit kit replaces worn factory rubber bushings in the rear toe arms with synthetic elastomer units engineered for improved handling, longevity, and driving confidence.

Key Benefits & Features

• Enhanced Suspension Geometry Stability — The synthetic elastomer formulation resists deflection better than stock rubber, helping maintain toe and alignment under load.

• Durability & Resistance — Formulated to resist oil, grease, ozone, and weathering for long service life.

• Self-Lubricating Design — Internal grease reservoirs provide continual lubrication, reducing friction and wear.

• Corrosion Protection — All metal components are plated with a protective coating to fend off rust and road‑salt damage.

• Complete Kit — Includes 4 bushings, 2 tubes, and the required grease for installation.

• Limited Lifetime Warranty — Backed by Whiteline’s warranty for their bushing kits.

Typical Installation Time: ~2 hours
Difficulty: Trade / Specialist level 

Installation & Tips

1. Safely raise and support the vehicle. Remove the rear toe arms.

2. Press out the old rubber bushings (heat may assist removal).

3. Press new Whiteline bushings in — use the supplied tubes to maintain alignment.

4. Apply the supplied molybdenum disulfide (LM) grease to the contact surfaces.

5. Reinstall toe arms and torque to factory specs, then perform a wheel alignment.

Pro Tip: Warm the suspension arms or bushing bores slightly to ease the install. Greasing contact areas and using a proper press tool helps prevent binding or damage during installation.
