Parts for your 2015 Subaru Impreza-Steering bushes

2015 Subaru Impreza steering bushes — what they do and when to replace them

Yes, the 2015 Subaru Impreza uses steering bushes. Technical documentation backs this up: the Subaru service manual for the 2015MY Impreza (GP/GJ) in the Steering (ST) section shows the rack-and-pinion assembly mounted to the front crossmember using rubber cushion bushes and brackets, and Subaru’s parts catalogue for the same model year lists a steering gear/rack mounting bush component. So “steering bushes” are relevant to this vehicle.

On this Impreza, the steering bushes sit between the electric power steering rack and the subframe. Their job is to locate the rack precisely while isolating vibration and harshness from the cabin. Good bushes help the wheel feel planted and keep toe settings stable over bumps and under braking.

When they wear, drivers can notice:

• Vague on-centre feel or a slight delay when turning in
• Clunks or knocks over potholes or speed humps
• Steering wheel nibble or wander on the motorway
• Visible rack movement on the crossmember when someone rocks the wheel
• Uneven tyre wear that a wheel alignment doesn’t fully cure

As part of routine servicing in Aussie and Kiwi conditions, it’s smart to inspect the steering bushes every 40,000–60,000 km or at any sign of noise or looseness. Look for cracking, hardening, distortion, or oil swelling. While the Impreza’s EPS means no power steering fluid leaks, engine oil or road grime can still attack rubber. Also check the rack brackets, subframe, inner/outer tie-rods, and the lower column joint at the same time.

Replacement is straightforward workshop work and often doesn’t require removing the rack:

1. Centre and secure the steering wheel, support the rack
2. Remove the rack brackets and old bushes
3. Clean the mounting faces, fit new bushes (correct orientation matters)
4. Refit brackets and torque fasteners to Subaru spec
5. Finish with a wheel alignment

Choose quality OEM-style rubber for factory comfort and NVH, or polyurethane for crisper steering feel and better durability, noting it can add a touch more vibration. Most workshops will book 1–2 hours for the job. If left too long, flogged bushes can let the rack shift, upsetting alignment and shortening tyre life, so sorting them early saves money and keeps the Impreza steering the way it should.

Popular questions about 2015 Subaru Impreza steering bushes

Do all 2015 Imprezas have steering rack bushes?
Yes. All 2015 Impreza variants use an electric power steering rack mounted to the crossmember with rubber bushes. They’re separate from sway bar bushes and specifically locate the steering rack.

How long do steering bushes last on a 2015 Impreza?
Many last 100,000–150,000 km, but heat, rough roads, and contamination can age them sooner. Replace if you notice clunks, vague feel, or visible cracking, or whenever alignment won’t hold.

Can the bushes be replaced without removing the rack?
Generally yes. The rack is supported, brackets are removed, and the bushes are swapped in situ. Some cars may need subframe slackening for access. An alignment afterwards is recommended.
