Parts for your 1998 Toyota Avensis-Control arms

1998 Toyota Avensis Control-Arms — Purpose, Service and Replacement

Control-arms are used on the 1998 Toyota Avensis (T22). The factory setup is a MacPherson strut front suspension with a lower arm (wishbone/control-arm) on each side, and a multi-link strut rear arrangement with trailing and lateral control arms. This configuration is documented in Toyota’s Avensis Repair Manual for 1997–2003 (Chassis—Suspension), the Toyota Electronic Parts Catalogue (T22 series, listing front lower arm sub-assemblies and rear links), and the Haynes Avensis manual for 1998–2003, which details inspection and replacement of front lower arms and rear links.

On the 1998 Avensis, control-arms do the heavy lifting of keeping the wheels pointing true while the suspension moves. The front lower arms (wishbones) link the chassis to the steering knuckle via a ball joint, with rubber bushes at the chassis end to soak up vibration. Out back, the multi-link setup uses trailing and lateral arms to control wheel alignment under load. All of this helps maintain tyre contact, tidy steering feel and predictable braking — the stuff that makes an Avensis feel settled on a rural B-road or a corrugated Kiwi backroad.

As part of routine servicing, it’s worth checking the arm bushes and ball joints every 20,000 km or annually. Tell-tales include clunks over bumps, a vague or wandering feel, uneven tyre wear on the inner or outer shoulders, pulling under braking or a steering wheel shimmy. Look for cracked, oil-soaked or perished bushes, torn dust boots and free play at the ball joint. A quick pry-bar test on a hoist will usually reveal any slop.

When it’s time to replace, many owners go for complete arms for the front — it’s often quicker and ensures a fresh ball joint and bushes in one hit. If doing bushes only, use quality rubber or polyurethane to suit how the car’s driven. Always torque bushing bolts at normal ride height, not with the suspension hanging, or the bushes will preload and fail early. After any arm or bush replacement — front or rear — book a four-wheel alignment, the T22 uses camber/toe adjustment that needs a proper setup. Replace any single-use (self-locking) nuts and mark eccentric bolts before removal to help the alignment tech.

Gentle driving habits help longevity: avoid kerb strikes, deep potholes and regular hopping speed humps. In coastal Aussie or NZ conditions, rinse the underbody now and then to keep corrosion off the metal sleeves. Expect control-arms and bushes to last anywhere from 100,000 to 200,000 km depending on roads and loads — earlier if the car sees rough tracks or heavy towing.

Popular question: How can you tell if the 1998 Toyota Avensis control-arms need replacing?

Listen for clunks over bumps, feel for vague steering or a pull under braking, and check for uneven tyre wear. A mechanic can pry-test the bushes and check the ball joint for play, cracked bushes or a loose joint mean it’s time.

Popular question: Do you need a wheel alignment after replacing control-arms on a 1998 Avensis?

Yes. Front and rear geometry is affected when arms or bushes are changed. A four-wheel alignment resets camber and toe, protecting tyres and restoring straight-line stability and steering feel.

Popular question: Should you replace just the bushes or the whole front lower control-arm?

If the ball joint is tight and the arm is sound, quality replacement bushes can be cost-effective. If the joint is worn or mileage is high, a complete arm saves time and often lasts longer, with new bushes and a fresh joint included.
