Parts for your 2012 Subaru Legacy-Steering bushes

2012 Subaru Legacy steering bushes: what they do and when to replace them

Yes, the 2012 Subaru Legacy (BM/BR) uses steering bushes. The factory rack-and-pinion is mounted to the front subframe with rubber bushes that isolate noise and vibration while keeping the rack located under load. This is documented in the Subaru Service Manual for the 2010–2014 Legacy/Outback steering system and reflected in Subaru’s parts catalog (rack-and-pinion mount bush/cushion listings). Aftermarket technical catalogues from brands like Whiteline and SuperPro also list direct-fit rack mount bush kits for 2009–2014 Liberty/Legacy models, confirming fitment.

On this model, the steering bushes act like small cushions between the steering rack and crossmember. They absorb road harshness, help the wheel feel steady on uneven bitumen, and keep the rack centred so the car tracks straight. When they wear, the rack can shift slightly under load, which shows up as vague steering, a shimmy through the wheel, or a clunk over potholes and corrugations.

Common signs the 2012 Legacy’s steering bushes are tired include:

• Noticeable free play at the wheel, especially on centre
• Clunks or knocks when turning into driveways or over speed bumps
• Tramlining or wandering at motorway speeds and uneven tyre wear
• A delay between steering input and the car changing direction

As part of regular servicing, it’s smart to inspect the rack mount bushes every 40,000–60,000 km, or sooner if the car sees rough rural roads. Look for cracked or oil-soaked rubber, or any visible shift of the rack when an assistant rocks the wheel left–right with the engine off. Many 2012 cars are now at the age where replacement pays dividends in steering feel.

Replacement is straightforward for a competent tech: support the rack, remove the rack-to-subframe bolts, swap the bushes (there are typically two, often one “D” and one round), then refit and torque to spec. On hydraulic racks, avoid stressing lines, on EPAS variants, keep the rack centred. A wheel alignment check afterwards is recommended, as fresh bushes can slightly alter toe. If the original rubber has perished, consider quality OEM-style rubber for OE compliance, or polyurethane for a firmer, more direct feel that holds alignment better—handy on kiwi backroads and Aussie highways. Either way, fresh bushes restore precision, reduce knocks, and make the Legacy feel right at the wheel again.

Popular questions about 2012 Subaru Legacy steering bushes

Do all 2012 Subaru Legacy models have steering rack bushes?
Yes. Regardless of trim, the BM/BR Legacy uses rubber rack-and-pinion mount bushes to locate the steering rack on the front subframe. The exact bush shape can vary slightly by rack type, but they’re serviceable parts on all variants.

How long do the steering bushes typically last?
In normal city and motorway driving they can last 100,000–150,000 km. Cars that see rough roads, big temperature swings, or fluid contamination (leaking power steering fluid on hydraulic racks) may need them earlier. If steering feels vague or there are clunks, an inspection is due regardless of kilometres.

Rubber or polyurethane—what’s best for replacement?
Rubber keeps factory refinement and is great for daily comfort. Polyurethane sharpens steering response and resists deformation, so it holds alignment better and lasts longer, though it can transmit a touch more feel. For a tidy daily driver, rubber is spot on, for a more connected drive or spirited weekend runs, poly is a good upgrade.
