Parts for your 2014 Subaru Impreza-Ball joints

2014 Subaru Impreza ball joints — what they do and when to replace them

Ball joints are absolutely relevant to the 2014 Subaru Impreza. Technical sources including the Subaru Factory Service Manual (GJ/GP chassis, MY2014), the Subaru Electronic Parts Catalogue, and mainstream workshop data (e.g., Autodata/Mitchell1/Haynes) all specify a front lower ball joint that links each front lower control arm to the steering knuckle on MacPherson strut suspension. The rear suspension on this model uses links and bushings rather than conventional serviceable ball joints, so “ball joints” for this car primarily means the fronts.

On a 2014 Impreza, the front lower ball joints let the steering knuckle pivot smoothly while the suspension moves up and down. They carry vehicle weight, allow steering angle, and keep the wheel aligned under brakes and cornering. When they’re healthy, steering feels precise and tyre wear stays nice and even. When they’re tired, you’ll often feel wander, clunks over bumps, or see scalloped tyres — and that’s a safety risk because a failed ball joint can let the knuckle move out of line.

These ball joints are sealed units — there’s no greasing nipple — so servicing is mostly about inspection. A good shop checks them at each service or WOF/roadworthy: look for torn dust boots, grease leakage, corrosion at the knuckle pinch area, and any free play during a lever test. If a boot is split or there’s noticeable play, replacement is the go, once grit gets in, they deteriorate quickly.

When it’s time to swap them out, most owners do both fronts together to keep steering feel consistent. Expect to re-check the wheel alignment afterwards, because toe and camber can shift slightly when the joint and arm are disturbed. Stubborn pinch bolts at the knuckle are common on Subarus, so a careful tech will soak them with penetrant and support the knuckle to avoid stressing the CV and brake hose. Quality matters — OEM or reputable aftermarket joints with proper corrosion protection are worth it for peace of mind.

Driving on rough roads, frequent beach launches, or high kilometres? Shorten the inspection interval. A quick look at each service can save tyres, sharpen steering, and keep this Impreza feeling tight and tidy.

• Common signs they’re due: clunking on bumps, vague steering, uneven tyre wear, squeaks when turning or braking, and any detectable play at the wheel or joint.
• After replacement: check alignment, torque fasteners to spec, and re-check for any boot twisting or leaks after a short shakedown drive.

Popular questions about 2014 Subaru Impreza ball joints

Do 2014 Imprezas have ball joints?
Yes — at the front. The model runs MacPherson struts with a lower control arm and a single lower ball joint per side connecting the arm to the steering knuckle. The rear uses multi-link arms with bushings rather than serviceable ball joints.

How often should the ball joints be replaced?
There’s no fixed kilometre interval because they’re sealed-for-life parts. Have them inspected at each service or WOF/roadworthy. Many last well past 100,000 km, but grit, corrosion, potholes and big tyres can shorten their life. Replace immediately if there’s play, noise, or a torn boot.

Can it be driven with a worn ball joint?
It’s not recommended. Worn ball joints can affect braking and steering accuracy and may fail without much warning. If there’s noticeable play or noise, park it until a mechanic inspects it — it’s a safety-critical part.
