2017 Subaru Impreza tie-rod end: purpose, checks and when to replace

Based on Subaru’s 2017MY Impreza (GK/GT) Service Manual (Steering section) and the Subaru FAST electronic parts catalogue, the 2017 Subaru Impreza uses a rack-and-pinion steering system with both inner and outer tie-rod ends. Major AU/NZ aftermarket catalogues also list direct-fit outer tie-rod ends for this model, confirming the part is relevant and fitted from factory.

The tie-rod end on a 2017 Impreza links the steering rack to the front steering knuckle via a compact ball-joint. It lets the wheel pivot smoothly while transmitting steering input, and it’s the adjustable point that sets front toe. When it’s in good nick, steering feels tight and predictable, tyres wear evenly, and the car tracks straight. When it’s tired, owners might notice vague steering, shimmy over bumps, or feathered tyre wear that sneaks up between services.

As part of regular servicing, it’s smart to inspect each outer tie-rod end. Look for a split or weeping dust boot, rust staining, or free play when the wheel is rocked at the 3 and 9 o’clock positions. Any clunking over driveways, abnormal tyre wear, or a steering wheel that won’t stay centred are cues to check the tie-rod ends pronto. On Kiwi WOF and Aussie roadworthy checks, any looseness here is a quick fail, so keeping them tidy is more than just good manners—it’s a safety must.

Replacement is straightforward for a trained tech. Mark the old position, count the turns off the inner rod, and fit the new end to roughly the same length. Avoid spinning the ball-stud during tightening, use the lock nut correctly, and torque to the spec in the Subaru manual. A wheel alignment is not optional—it’s essential to bring toe back into spec and protect the tyres. On EPS-equipped Imprezas, many alignment machines will also verify or reset the steering angle sensor if needed.

Quality counts. OE or reputable aftermarket ends with proper dust boots and grease sealing will go the distance on Aussie and New Zealand roads. Replacing in pairs isn’t mandatory, but if one side’s worn, the other should be checked closely. With regular inspections every service interval and prompt replacement when wear appears, the Impreza’s steering stays sharp, safe, and kind to tyres.

• Key checks: boot condition, play at 3/9 o’clock, unusual tyre wear, clunks or steering wander
• After replacement: always perform a professional wheel alignment (and SAS check if required)

Popular questions about 2017 Subaru Impreza tie-rod ends

How long do tie-rod ends typically last on a 2017 Impreza?
Service life depends on road conditions and driving style. Many will run well past 80,000 km, but corrugations, potholes, and frequent kerb knocks can shorten their life. Regular inspections at each service are the best way to catch wear early and avoid chewing through tyres.

What symptoms point to a worn tie-rod end on this model?
Common signs include a clunk over bumps, steering that feels loose or wanders, uneven or feathered tyre wear, and a steering wheel that won’t stay centred. A torn dust boot or visible rust around the ball-joint is also a red flag.

Do both tie-rod ends need replacing, and is an alignment required?
Only the worn side must be replaced, but the opposite end should be checked carefully. A wheel alignment is always required after replacement to set toe correctly, and some workshops will verify or reset the steering angle sensor as part of the alignment process.
