Parts for your 2006 Subaru Impreza-Control arms

2006 Subaru Impreza Control Arms — Purpose, Service Tips, and When to Replace

Based on the Subaru Factory Service Manual for the 2006 Impreza (GD/GG) and OEM parts catalogues used by Subaru dealers and aftermarket suppliers (e.g., listings for “front lower control arm”/“front lower arm” and associated bushings and ball joint), this model absolutely uses control arms. At the front, the 2006 Subaru Impreza runs a MacPherson strut setup with a single lower control arm per side (steel on many trims, aluminium on some WRX/STI variants). The rear uses multi-link components commonly identified as lateral and trailing arms that perform control-arm functions.

For anyone keeping a 2006 Impreza tight and tidy on Kiwi and Aussie roads, the control arms are key to ride quality, steering feel, and tyre wear. They locate the wheel and manage camber and caster as the suspension moves, with rubber or polyurethane bushings absorbing vibration while the ball joint lets the steering knuckle pivot smoothly. When these parts age, they can cause vague steering, clunks, and uneven tyres, and can throw out the wheel alignment.

Servicing the control arms on a 2006 Subaru Impreza is straightforward for a trained tech and a smart move during a suspension refresh. If the arm itself is straight and crack-free, fresh bushings and a new ball joint can restore factory feel. If the arm is bent or corroded, complete replacement arms are often cost-effective. Either way, a four-wheel alignment is a must afterward to bring camber, caster, and toe back into spec.

• Common signs it’s time: clunks over bumps, steering shimmy, wandering at highway speeds, or inner/outer tyre edge wear.
• Good maintenance habits: inspect front lower control arm bushings and ball joints every 20,000–30,000 km, check after kerb strikes or potholes, replace in axle pairs for consistent handling.
• Fitment tips: torque bushings at ride height to avoid preload, use new ball joint pinch bolts and nuts, consider upgraded bushings for sharper turn-in on WRX/STI.

With fresh control arm hardware, the 2006 Impreza keeps its trademark Subaru stability, braking confidence, and crisp steering feel—ideal for daily commuting and spirited weekend drives alike.

Does a 2006 Subaru Impreza have control arms?

Yes. Technical documentation for the 2006 Impreza confirms front lower control arms are standard across the range, with bushings and a ball joint connecting to the steering knuckle. The rear uses multi-link arms that serve similar control functions.

How often should the control arm bushings or ball joints be replaced?

There’s no fixed interval, condition-based replacement is best. Many owners see 120,000–180,000 km from originals, but harsh roads, heat, and age can shorten that. Inspect at regular services and replace if cracked, leaking, loose, or noisy. Always align the car afterwards.

Is it safe to drive with worn control arms?

It’s not recommended. Excess play can affect braking stability and steering accuracy, and severe wear can risk ball joint separation. If you notice clunks, pulling, or rapid tyre wear, get it checked promptly and repaired before it becomes a safety issue.
