Parts for your 2002 Daihatsu Gran move-Control arms

2002 Daihatsu Gran Move Control Arms

Control arms are absolutely relevant to the 2002 Daihatsu Gran Move (G301/G303, also known as Pyzar). The front end runs a MacPherson strut setup with a single lower control arm (wishbone) per side, while the rear is a torsion-beam arrangement without conventional control arms. This configuration is documented in the Daihatsu G300-series workshop literature and reflected in OEM parts catalogues (Toyota/Daihatsu EPC) and reputable aftermarket catalogues that list a front lower arm assembly for the Gran Move.

On this model, the front control arms locate the hub and strut, manage alignment angles, and let the suspension move up and down while keeping everything pointing straight. Each arm carries a pressed-in ball joint at the wheel end and rubber bushes at the chassis end. When these wear, the Gran Move can feel vague, clunk over bumps, or scrub tyres prematurely.

Servicing guidance is pretty straightforward. If there’s knocking on rough roads, vague steering off-centre, pulling under brakes, or uneven tyre wear, have the front arms, bushes and ball joints inspected. Any torn bushes, excessive ball joint play, or bent arms call for replacement. Many workshops will fit complete arms rather than pressing new bushes/ball joints, as it’s faster and often more cost-effective on this platform.

When replacing, consider doing both sides together to keep handling even. Always torque the pivot bolts at normal ride height (not with the wheels hanging) to avoid preloading the new bushes. Follow up with a wheel alignment—caster and camber are largely fixed by the arm and strut geometry, while toe needs setting after any arm work. It’s also a good time to eyeball sway bar links and strut tops.

Quality matters. Genuine or reputable aftermarket arms with OE-style rubber bushes tend to ride quieter and last longer on Aussie and Kiwi roads. Expect bush lifespan to vary with conditions, city driving on smooth tarmac can see 100–150,000 km, while rougher surfaces or frequent loads may bring that forward. During routine services, a quick check for bush cracking, perished rubber, or grease seepage from the ball joint goes a long way. Keeping tyres correctly inflated and avoiding kerb strikes helps protect those arms and your alignment, saving money on tyres and keeping the Gran Move tracking nicely.

• Common symptoms: clunks over bumps, steering wander, uneven tyre wear, vibration under braking.
• Best practice: replace in pairs, torque at ride height, and book an alignment straight after.
• Check related parts: sway bar links, strut mounts, and inner/outer tie rods.

Popular questions

How long do the Gran Move’s control arm bushes and ball joints typically last?
In normal mixed driving, it’s common to see 100–150,000 km from OE-quality bushes and ball joints. Harsher roads, heavy loads, or frequent speed humps can shorten that interval. Regular inspections during scheduled services help catch wear early before it affects tyres or braking feel.

Do I need a wheel alignment after replacing control arms on a 2002 Gran Move?
Yes. Changing a control arm alters the relationship of the hub to the chassis, which affects toe and can nudge camber. An alignment right after installation is the safest way to protect tyres and restore crisp steering.

Is it better to press new bushes and a ball joint, or fit complete arms?
Both approaches work, but complete arms are often quicker and can be more economical once labour is considered. They also ensure the arm isn’t fatigued and that new bushes and ball joint are matched. If keeping the original arms, make sure pressing is done with proper jigs to avoid distorting the arm.
