Parts for your 2000 Toyota Crown-Control arms

2000 Toyota Crown control arms — what they do and how to look after them

Control arms are absolutely fitted to the 2000 Toyota Crown. Toyota’s S170-series Crown factory repair manual (1999–2003) and the Toyota Electronic Parts Catalogue list a double-wishbone front suspension (with upper and lower control arms and ball joints) and a multi-link rear suspension that uses several control arms/lateral links. So the part is relevant on this model, both ends of the car.

On the Crown, control arms locate the wheel hubs to the chassis and let the wheels move up and down without knocking alignment out. They keep camber and caster steady, control toe change through the stroke, and work with the springs, shocks, and stabiliser bars to deliver that calm, planted ride Crowns are known for. The arms pivot on rubber or hydraulic bushes and typically carry ball joints at the steering knuckle, so when those wear, owners feel it straight away in steering feel and tyre wear.

For ongoing servicing, a quick visual and hands-on check of the control arms every 20,000 km is smart motoring. Look for cracked or perished bushes, torn ball joint boots, rust at welds, and any play when the wheel is rocked at 3 and 9 o’clock. On vehicles driven on coarse chip or rural roads in Australia and New Zealand, bushes often age faster, expect replacement anywhere from 80,000 to 150,000 km depending on use.

• Common signs of wear: clunks over bumps, shimmy under braking, vague steering or tramlining, uneven or rapid inner-edge tyre wear, and poor return-to-centre.
• Replacement tips: change arms or bushes in axle pairs, torque all fasteners at normal ride height, and book a full four-wheel alignment straight after.

Owners can choose complete replacement arms (often the tidy option when ball joints are riveted or bushes are heavily worn) or press-in bushes and separate ball joints when the arm itself is sound. Quality aftermarket or genuine parts make a real difference to NVH and longevity. Always follow the Crown’s service manual torque settings and note any single-use nuts. A fresh set of bushes and joints will restore quietness, keep tyres wearing evenly, and bring back that smooth, confident Crown steering feel that makes long kilometres effortless.

Does the 2000 Toyota Crown have control arms front and rear?
Yes. The S170 Crown runs a double-wishbone front end with upper and lower arms, plus a multi-link rear that uses several control arms/lateral links. Both ends rely on arms, bushes, and ball joints to hold alignment under load.

How long do Crown control arm bushes typically last?
Anywhere from about 80,000 to 150,000 km is common, depending on road quality, loads, and age. Heat, oil contamination, and rough chip seal can shorten life, while gentle metro use can stretch it further.

Can the bushes be replaced, or do the whole arms need changing?
Both approaches are valid. If the arm is straight and rust-free, pressing in quality bushes and fitting new ball joints can be cost-effective. If joints are integrated or the arm is tired, complete arms save time and often reduce NVH. Always finish with a wheel alignment.
