Parts for your 2012 Subaru Impreza-Steering bushes

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

Based on technical sources, steering bushes are indeed used on the 2012 Subaru Impreza (GP/GJ). The Subaru Service Manual for GP/GJ (Steering, “ST” section) shows the electric power steering rack mounted to the front crossmember via rubber bushes, and the Subaru FAST electronic parts catalogue lists rack-mount insulators for this model series. Aftermarket catalogues from respected suspension specialists also offer direct-fit rack-mount bush kits for 2012 Impreza, further confirming fitment. So yes—this model runs steering bushes, and they’re very relevant to steering feel and NVH.

These bushes sit between the steering rack housing and the subframe. Their job is to isolate vibration and noise, keep the rack located under load, and help the car track straight when the road gets rough. When they age, harden, or tear, the rack can shift slightly during cornering or over bumps. Drivers typically notice a vague on-centre feel, a knock or clunk on turn-in, or the wheel “self-correcting” on cambered roads—classic worn-bush behaviour.

For Aussie and Kiwi conditions—heat, UV, and plenty of rough chip—checking the rack bushes every 40,000–60,000 km (or during each major service) is a smart move. Look for cracks, deformation, oil-soak, or shiny witness marks that show the rack has been moving. Also verify the rack bracket bolts are torqued to spec from the service manual, and inspect the lower steering shaft/universal joint while you’re there.

Replacement is straightforward for a trained tech. OE-style rubber keeps the ride civil, high-quality polyurethane tightens steering response at the cost of a touch more road feel. On refit, load the suspension at ride height before final torque, and book a wheel alignment afterwards—bush movement and subframe position can nudge toe and steering-centre. Because this Impreza uses electric power steering, some scan tools can recentre the steering angle if needed, follow the Subaru procedure in the ST section. Fresh bushes often transform steering precision, which helps with WOF/rego inspections and everyday confidence.

• Typical symptoms: clunk over bumps, vague steering, tramlining, or the wheel not returning to centre cleanly.
• Good practice: inspect at major services, replace in pairs, choose quality bushes, and align after the job.

Does the 2012 Impreza actually have steering rack bushes?

Yes. The GP/GJ chassis mounts its EPS rack to the subframe with rubber bushes per the Subaru Service Manual (ST). Parts listings and aftermarket kits corroborate this.

How long do the steering bushes last on a 2012 Impreza?

Anywhere from 80,000 to 150,000 km is common, but climate, road quality, and fluid leaks speed wear. Inspect at each major service or if you notice steering play or knocks.

Do I need a wheel alignment after replacing rack bushes?

Highly recommended. Disturbing the rack/subframe can alter toe and steering-centre. An alignment restores straight-line tracking and even tyre wear.
