Parts for your 2009 Subaru Impreza-Rack boots

2009 Subaru Impreza rack boots: purpose, care, and when to replace

Rack boots are absolutely fitted to the 2009 Subaru Impreza. Technical references including the Subaru Factory Service Manual for the 2009 Impreza/WRX (Steering section) and the Subaru Electronic Parts Catalogue (EPC/FAST) specify bellows-type steering rack boots on both sides of the rack-and-pinion assembly. Aftermarket and OEM catalogues for the 2008–2011 GE/GH Impreza also list left and right rack boots, confirming this component is relevant to the model.

On this Impreza, the rack boots (also called bellows) keep dust, water, and road grit out of the steering rack while sealing in grease for the inner tie-rod joints. They flex as the steering moves, protect the rack seals, and help the steering feel stay smooth and accurate. Given Aussie and Kiwi conditions—heat, UV, corrugations, and coastal salt—boots can harden, crack, or split over time.

It’s smart to have the rack boots checked at each service (roughly every 10–15,000 km). A quick torch inspection under the bonnet or on a hoist will spot early damage before it snowballs into a pricier rack overhaul.

• Replace if there are cracks, splits, perishing, or loose/damaged clamps.
• If there’s power steering fluid pooled inside a boot, the rack’s internal seal may be leaking—address this promptly.
• Grease flung out, dirt packed inside, or a clicking/knocking on steering lock are red flags.

When replacing, use quality boots and new clamps, and re-grease the inner tie-rod ball joint. The outer tie-rod end usually needs to come off, so a wheel alignment is recommended afterwards. Counting the turns when removing the tie-rod end can get it close, but proper alignment keeps tyre wear and steering feel sweet.

Because ageing tends to be symmetrical, many techs replace rack boots in pairs. It’s relatively low-cost compared with the pain of a contaminated or corroded rack. If the car sees gravel roads, beach launches, or lots of city kerb strikes, shorten inspection intervals.

Bottom line: fresh, sealed rack boots help the 2009 Subaru Impreza steer precisely, protect the hydraulic rack, and save money over the long run.

How often should rack boots be checked on a 2009 Impreza?

Have them inspected at every routine service (about 10–15,000 km), and sooner after off‑road detours, floodwater exposure, or a hard front-end knock. Regular checks catch minor splits before they let grit into the rack.

Can driving with a torn rack boot damage the steering rack?

Yes. A torn boot lets water and debris in, washing out grease and wearing the inner tie-rod and rack seals. If power steering fluid gathers inside the boot, that hints at an internal rack leak—don’t leave it, fix it before the rack is damaged.

Do both rack boots need replacing at the same time?

It’s often recommended. If one boot has perished, the other usually isn’t far behind. Labour overlaps and a matching pair keeps both sides protected and the steering feel consistent.
