Parts for your 1998 Toyota Altezza-Control arms

1998 Toyota Altezza Control Arms

Technical sources including Toyota’s New Car Features (XE10, 1998–1999), the Lexus IS200/Altezza chassis and suspension workshop manual, and Toyota’s Electronic Parts Catalogue identify the 1998 Toyota Altezza (XE10) as running double‑wishbone suspension front and rear, with upper and lower control arms at each corner. That means control arms are absolutely relevant to this model.

On the 1998 Altezza, the control arms (wishbones) locate the wheel hubs and keep the alignment steady under braking, cornering and over bumps. They set camber and caster via fixed geometry and bushings, while the ball joints let the suspension articulate freely. In everyday terms, they’re the quiet heroes behind the car’s crisp turn‑in, planted mid‑corner feel, and predictable tyre contact. When the bushes or ball joints wear, geometry drifts and the car starts to tramline, clunk, or chew out tyres well before their time.

For routine servicing, it’s smart to inspect the control arm bushes and ball joints every 10,000–15,000 km or at each six‑monthly service. A pry‑bar check for excess play, visual cracks in the rubber, torn dust boots, and any leaked grease are quick giveaways. Many owners notice issues as:

• Clunks over speed humps or driveway entries
• Steering shimmy or vibration under braking
• Uneven or inner‑edge tyre wear despite correct pressures
• Pulling to one side or wandering on the motorway
• Straight‑ahead steering feeling “loose”

When replacements are due, quality bushes (rubber or polyurethane depending on NVH preference) and OE‑spec ball joints keep the Altezza’s balance intact. Always torque control arm bolts at normal ride height to avoid pre‑loading the bushes, and book a full four‑wheel alignment straight after. In Aussie and Kiwi conditions—heat, rain, plus the odd corrugated backroad—bush life can vary, spirited RS200/AS200 driving or track days shorten service intervals. Replacing in axle pairs keeps handling even side‑to‑side. Surface rust on arms is common, heavy corrosion or ovalled bolt holes mean it’s time for full arm replacement rather than just bushes. With the right parts and setup, the XE10 rewards the effort with that trademark sharp, confidence‑inspiring feel kilometre after kilometre.

Popular questions about 1998 Toyota Altezza control arms

Does the 1998 Altezza use control arms or MacPherson struts?
The 1998 Altezza (XE10) uses double‑wishbone suspension front and rear, so it has upper and lower control arms at both ends rather than MacPherson struts. This design is a big part of its precise steering and stable camber control.

How often should Altezza control arm bushes be replaced?
There’s no hard expiry, but many see 80,000–150,000 km depending on driving, climate, and road quality. Track use or rough roads can shorten that. Check at every service and replace at the first signs of cracking, play, or noise.

Can just the bushes be replaced, or does the whole arm need changing?
Yes, bushes and ball joints can often be serviced separately on the XE10. If the arm is bent, cracked, or the ball joint is non‑serviceable, a complete arm is the better call. Either way, finish with a proper alignment.
