Parts for your 1989 Suzuki Swift-Control arms

1989 Suzuki Swift control arms — what they do and how to look after them

Based on factory and aftermarket technical references — including the Suzuki Swift/Cultus Service Manual (1988–1992, Front Suspension section), the Haynes Repair Manual for Suzuki Swift/Geo Metro (1985–2001, Suspension and Steering), and the Suzuki Electronic Parts Catalogue (Group 45 – Front Axle/Lower Arm) — the 1989 Suzuki Swift uses front lower control arms as part of its MacPherson strut front suspension. These arms locate the hub, control wheel motion, and carry the lower ball joint, the rear of most 1989 Swifts uses a beam/trailing-arm setup rather than conventional “control arms”.

On a 1989 Swift, the control arm (often called the lower arm in Suzuki literature) links the body to the front hub via two rubber bushes at the chassis end and a ball joint at the wheel end. Its job is to keep the wheel tracking straight while allowing the suspension to move up and down. It also helps manage alignment angles and works with the sway bar to keep the car settled in corners. When these bushes or the ball joint wear, drivers cop clunks over bumps, vague steering, or uneven tyre wear.

Servicing advice for Aussie and Kiwi owners is pretty straightforward. Inspect the control-arm bushes and ball joint boots at each service or WOF/rego check, especially on high-kilometre or coastal cars where rubber perishes and metal corrodes. Oil-soaked, cracked, or split bushes and any loose or torn ball joint boots are a cue for replacement. There’s no fixed replacement interval — age, roads, and loads dictate life — but many originals are well past their best by now.

When replacing, it’s fine to fit a complete arm (new bushes and ball joint pre-assembled) or, on variants where it’s serviceable, a separate ball joint and bushes. If the bushes look tired, a complete arm is often the best value. Always tighten rubber-bushed bolts at normal ride height to avoid preloading the bushes, then get a proper wheel alignment. It’s also smart to check sway bar links, strut tops, and inner/outer tie rods at the same time for a tidy, quiet front end.

• Common symptoms: clunks on bumps, steering shimmy, wandering, brake pull, and inner/outer tyre wear.
• Parts naming: “Lower arm” or “front lower control arm” in Suzuki EPC and manuals.

Popular questions

Does the 1989 Suzuki Swift have control arms front and rear?

Front, yes — it uses MacPherson struts with lower control arms and a ball joint. The rear is a beam/trailing-arm arrangement rather than separate upper and lower control arms, so “rear control arms” aren’t typically listed for this model.

How often should the control-arm bushes be replaced?

There’s no set kilometre interval. Check them at every service or WOF/rego. Replace if the rubber is cracked, perished, oil-soaked, or if there are clunks, poor steering feel, or uneven tyre wear. Given the age of these cars, many benefit from fresh arms or bushes regardless of mileage.

Can the ball joint be replaced on its own, or is a whole arm needed?

Many 1989 Swift variants allow the ball joint to be replaced separately, others are simplest to service with a complete arm. If the bushes are also tired, a full arm is usually the most economical and time-efficient option, followed by a wheel alignment.
