Parts for your 2004 Subaru Impreza-Steering bushes

2004 Subaru Impreza Steering Bushes – What They Do and When to Replace Them

Technical sources confirm that steering bushes are fitted to the 2004 Subaru Impreza. The Subaru Factory Service Manual (MY2004 Impreza, Steering section) details the rack-and-pinion mounted to the front crossmember via rubber cushion bushes. Subaru’s electronic parts catalogue lists these as cushion rubbers for the steering gearbox, and major suspension brands list direct-fit replacements (e.g., Whiteline KSR202 and SuperPro SPF2070K) for 1993–2007 Impreza models, including 2004 WRX/STI.

On the 2004 Impreza, the steering rack bushes secure the rack to the subframe while isolating vibration. Their job is to keep the rack located precisely under load so the wheel stays true on-centre, feedback feels consistent, and the car tracks straight. Over time, factory rubber can soften, crack, or oval out, especially with higher kilometres, repeated kerb strikes, or if power steering fluid has leaked onto the rubber. When that happens, drivers notice vague steering, tramlining, a clunk over bumps, or the wheel needing little corrections on the motorway.

Owners chasing a tidy, confidence-inspiring feel will often refresh the rack bushes as part of a steering service. Rubber OEM-style bushes keep it quiet and comfy, polyurethane options sharpen response and reduce rack movement but can add a touch more road feel and noise. If going poly, use the supplied grease to prevent squeaks. Either way, it’s a relatively small job that makes a big difference.

• Common signs they’re tired: on-centre play, wandering, knock/clunk on turn-in or over ripples, and uneven steering effort.
• Good practice: inspect at regular services, especially if there’s evidence of fluid leaks around the rack or subframe.

Replacement tips: support the rack so hoses aren’t stressed, replace bushes one side at a time to keep alignment, and torque the mounting brackets to the factory spec from the Subaru manual. After fitting, a wheel alignment is recommended to make sure the steering wheel sits straight and toe is spot on. While you’re there, check the lower column joint and tie-rod ends for play, and sort any power steering leaks—the new bushes will last much longer if they’re not bathing in fluid.

For cars with bigger wheels, stiffer springs, or plenty of city kerbs and potholes, expect bush wear sooner, for gentle highway use, they can last years. Either way, fresh bushes restore that planted, confidence-inspiring Subaru steering feel Aussies and Kiwis love.

Popular questions about 2004 Subaru Impreza steering bushes

Do all 2004 Subaru Imprezas have steering rack bushes?
Yes. Across the GD/GG range (including WRX and STI), the rack mounts to the front crossmember using rubber cushion bushes. Exact hardness can vary by model, but the concept and service approach are the same.

Which is better: rubber or polyurethane bushes for daily driving?
Rubber keeps it quiet and comfy for commuting. Polyurethane tightens steering feel and reduces rack movement, great for spirited driving, but may pass a bit more vibration into the cabin. Most daily drivers stick with rubber, weekend warriors often pick poly.

Do you need a wheel alignment after replacing steering rack bushes?
It’s strongly recommended. Even if toe hasn’t moved much, aligning ensures the steering wheel sits dead straight and the Impreza tracks nicely at motorway speeds.
