Parts for your 2016 Subaru Forester-Ball joints

2016 Subaru Forester ball joints

Ball joints are absolutely used on the 2016 Subaru Forester. Technical sources including the Subaru Factory Service Manual for the 2016MY Forester (SJ) identify a front lower ball joint at each steering knuckle within the MacPherson strut front suspension, and a press-in ball joint at the rear knuckle used with the double-wishbone rear suspension. Subaru’s OEM parts catalog lists these as the front arm ball joint and the rear knuckle/lateral link ball joint, confirming they’re fitted as standard components on this model.

On a 2016 Forester, ball joints act like the pivot points between the suspension arms and the wheel hub/knuckle. They let the wheels move up and down with bumps while still steering smoothly. In day-to-day driving, they cop a fair bit of load from potholes, corrugations, speed humps and kerbs, so keeping an eye on them is a smart move during servicing.

The factory ball joints are sealed, so they’re not a grease-and-go item. The best maintenance is regular inspection: at each service (roughly every 10,000 km), check the dust boots for splits, look for any grease fling, and test for play with the wheel off the ground. A pry-bar check at the control arm and knuckle can reveal looseness, and any measurable movement outside specs means it’s time for replacement. If the boots are torn or there’s rust staining around the joint, don’t wait—grit will quickly wear the socket.

Common tell-tales of a tired ball joint include:

• Clunks or knocks over bumps or when turning at low speed
• Wandering steering, tramlining, or vague on-centre feel
• Uneven or accelerated tyre wear
• Metal-on-metal squeaks that change with suspension movement

Replacement on the Forester’s front end usually involves removing the pinch bolt at the knuckle and separating the taper—these can seize in place, so penetrating oil, heat, and patience help. On the rear, the press-in ball joint at the knuckle may require a suitable puller/press set. It’s wise to replace in axle pairs for consistent handling, renew any pinch bolts or split pins, and torque everything to spec. After front or rear ball joint work, a wheel alignment is recommended to protect tyres and restore straight-line stability.

Quality OEM-equivalent joints and correct installation make a big difference to steering feel and tyre life. If there’s any doubt, a quick inspection now beats buying new tyres sooner than needed.

How long do Forester ball joints typically last?

On Aussie and Kiwi roads, many see 120,000–200,000 km, but gravel, heavy loads, and harsh potholes can shorten that. Regular checks at service time help catch wear before it affects tyres or safety.

Do worn ball joints cause vibration or uneven tyre wear?

Yes. Excess play lets the wheel change camber and toe as it moves, which can show up as shimmy, steering vagueness, and feathered tyre edges. If tyre wear looks odd, include the ball joints in the suspension check.

Is a wheel alignment needed after ball joint replacement?

It’s recommended. Even if adjustments aren’t directly disturbed, tolerances shift when fresh joints are fitted. A proper alignment helps the Forester track straight and protects your tyres.
