Parts for your 2018 Subaru Legacy-Steering bushes

2018 Subaru Legacy (Liberty) steering-bushes — are they even a thing?

Short answer: steering-bushes aren’t a separate, serviceable part on the 2018 Subaru Legacy (known as Liberty in Australia). Subaru’s own technical info backs this up. The 2018 model uses an electric power steering rack that’s bolted directly to the front crossmember. In the Subaru Service Manual (2018 Legacy/Liberty, Power Assisted System (Electric): Steering Gearbox removal/installation) there’s no prescribed replacement of rack “bushes,” and the Subaru FAST parts catalogue (Group 34 Steering, illustration for Steering Gear & Linkage) lists the rack assembly, inner/outer tie-rods, and hardware, but no stand-alone rack-mount bushes as a service item.

Why that matters: older Subarus (and plenty of other makes) ran separate rubber bushes to isolate the steering rack. On the 2018 Legacy/Liberty, isolation and NVH control are designed into the rack housing and crossmember interface, so there aren’t individual “steering-bushes” to swap out. If there’s free play, wandering, clunks or a vague on-centre feel, the fix usually isn’t “steering-bushes” — it’s elsewhere in the front end.

What owners and techs should check instead:

• Inner and outer tie rod ends for play or torn boots
• Front lower control arm rear bushes (a common wear item that affects steering feel)
• Stabiliser (sway) bar bushes and links for knocks over bumps
• Strut top mounts and front wheel bearings
• Steering column universal joints for stiffness or notchiness
• Rack-to-subframe fasteners for correct torque per the Service Manual

As part of routine servicing in AU/NZ conditions, a visual and pry-bar check of the above every 20,000 km or 12 months is smart, with a wheel alignment after any tie-rod or control arm work. If the rack itself is worn or leaking (rare on this generation’s EPS), Subaru procedures point to repairing or replacing the rack assembly rather than fitting bushes.

For anyone hunting aftermarket “rack bushes”: those kits suit earlier models. The 2018 platform isn’t designed for retrofit bushes, and forcing the issue can spike NVH, misalign the rack, or stress the housing. Sticking with the factory design and keeping the related suspension and steering joints in good nick is the way to restore sharp, safe steering feel.

FAQs

Does the 2018 Subaru Legacy/Liberty have steering-bushes I can replace?
No. Technical sources — the Subaru Service Manual for the electric power steering system and the Subaru FAST parts catalogue (Group 34 Steering) — don’t list separate rack mount bushes as a service part. The rack is direct-mounted to the crossmember, and any isolation is built into the assembly and mounting design.

What causes vague steering or clunks if it’s not the steering-bushes?
Most commonly: inner/outer tie rods, front lower control arm rear bushes, sway bar links/bushes, and sometimes strut top mounts. Also check the steering column U-joints and ensure the rack mounting bolts are torqued correctly. An alignment can mask minor issues, but worn joints or bushes will keep the steering feeling off until they’re replaced.

How should the steering system be maintained on a 2018 Legacy/Liberty?
During regular services (about every 20,000 km), inspect tie rods, control arm bushes, sway bar gear and column joints, look for split boots, rust dust, or free play. After any front-end work, get a proper wheel alignment and ensure tyre pressures and tyre wear are even. Use torque specs from the Subaru Service Manual and quality parts to keep the steering precise and quiet.
