1999 Toyota Altezza Control Arms — What They Do and How to Look After Them

Per Toyota’s New Car Features (XE10) and the Lexus IS200/Altezza Chassis Repair Manual, the 1999 Toyota Altezza runs double-wishbone suspension front and rear, which means control arms are very much part of the package. Each corner uses arms and links to keep the wheel hub located precisely, manage alignment angles, and deliver that tidy Altezza handling people love.

Control arms connect the wheel assemblies to the subframes, pivoting on bushes and ball joints so the suspension can move while the tyres keep a consistent contact patch. On an Altezza, this design sharpens steering feel, holds camber through corners, and reins in toe change under braking and acceleration. The upshot is confident turn-in and predictable grip, which is why the platform earned its reputation for balance.

With age and kilometres, the rubber bushes harden, crack, or oil-soak, and ball joints can develop play. That shows up as clunks over bumps, steering wander, vibration under braking, or uneven tyre wear. During regular servicing, it’s smart to ask for a chassis once-over that includes:

• Visual checks for split or weeping bushes and torn ball joint boots
• Pry-bar tests for play at arm bushes and joints
• Road test for knocks, shimmy, or tramlining
• Alignment check for off-spec camber/caster/toe

When replacement time rolls around, many owners choose to fit arms in pairs (left/right) to keep handling balanced. Fresh genuine-type rubber bushes preserve factory ride and NVH, while quality polyurethane can sharpen response at the cost of a touch more vibration—great for spirited weekend drives, less ideal if the car’s a daily on rough Kiwi or Aussie roads.

A few tips that make life easier: torque the pivot bolts at normal ride height so the bushes aren’t preloaded, replace any single-use nuts/bolts specified by the workshop manual, and book a wheel alignment immediately after the job. If the Altezza is lowered, ask the shop to set camber and toe to suit how it’s driven and how the tyres wear. Many cars see their first big round of suspension refresh between 150,000–250,000 km, but climate, road quality, and tyre setup can push that earlier.

Sorted control arms make a noticeable difference—quieter over bumps, straighter on the motorway, and that crisp Altezza steering feel back where it should be.

FAQs

Do I need a wheel alignment after replacing control arms on an Altezza?

Yes. Any time control arms, camber bolts, or ball joints are disturbed, alignment can shift. A proper alignment brings camber, caster, and toe back into spec so the car tracks straight and the tyres wear evenly.

Rubber or polyurethane bushes—what suits a 1999 Altezza best?

Rubber keeps the factory ride comfort and low NVH, perfect for daily driving. Polyurethane adds precision and sharper response, which keen drivers appreciate, but you may notice a bit more vibration and noise on coarse-chip roads common in Australia and New Zealand.

What are the tell-tale signs my Altezza’s control arms are worn?

Clunks over speed bumps, vague steering, pull or wander on the motorway, and uneven or rapid tyre wear are common signs. If the steering wheel shudders under braking or you see cracked bushings or torn ball joint boots, it’s time for an inspection.
