Parts for your 2023 Mitsubishi Triton-Control arms

2023 Mitsubishi Triton control arms

Based on technical sources, control arms are absolutely relevant to the 2023 Mitsubishi Triton. Mitsubishi Motors Australia’s MY23 Triton specifications list a double wishbone front suspension with coil springs, which uses upper and lower control arms, while the rear is a leaf-spring live axle with no rear control arms. The Mitsubishi Triton/L200 workshop manual for front suspension confirms upper and lower arms with ball joints and inner bushes, and major aftermarket catalogues and OEM parts diagrams for the MR-series (2019–2023) list replacement front control arms, bushes and ball joints for this model.

On the 2023 Triton, the front control arms do the heavy lifting for steering precision and ride comfort. They link the front hubs to the chassis, keeping camber and caster in check as the wheels move up and down. Each arm pivots on inner bushes and carries a ball joint at the hub end, so the wheel tracks straight, tyres wear evenly, and the ute feels planted on-road and sure-footed off-road.

For servicing, it’s smart to treat control arms as consumable suspension hardware—especially if the Triton tows, carries loads, or sees corrugations and rutted trails. Bushes harden, crack or delaminate over time, ball joints can develop play. Either issue leads to steering shimmy, clunks over bumps, wandering, or inner/outer tyre wear.

• Inspection: Check control arm bushes and ball joints at every service or at least every 20,000–40,000 km. Look for torn dust boots, cracked rubber, rust staining, or free play with a lever.
• Replacement: If there’s play, noise, or alignment can’t be held, replace the affected arm or components. Many techs replace arms in pairs (left/right) to keep handling balanced.
• Hardware: Camber bolts can seize in the inner bushes—budget for new bolts and nuts. Torque all fasteners at ride height to avoid preloading the bushes.
• Alignment: Always complete a four-wheel alignment after arm, bush or ball joint work to restore camber/caster and protect tyre life.
• Component choice: OE-style rubber bushes keep NVH low, performance polyurethane can sharpen response but may increase cabin feel—choose to suit the Triton’s usage.

Kept in good nick, front control arms help the 2023 Triton steer cleanly, brake straight and look after its tyres, whether it’s a weekday workhorse or a weekend tourer.

Does the 2023 Triton have rear control arms?
Not on the rear. The 2023 Triton runs a leaf-spring live axle at the back, so the springs locate the axle and no rear control arms are fitted. The control arms are up front as part of the double wishbone setup, with upper and lower arms, bushes, and ball joints.

How often should control arm bushes or ball joints be replaced?
There’s no fixed interval, it depends on use. Inspect at each service and expect wear anywhere from 80,000 km sooner if it tows, carries heavy loads, or sees rough roads. Replace when there’s play, split boots, fluid leakage (on sealed joints), metal-on-metal noise, or recurring alignment drift.

Do you need a wheel alignment after replacing control arms?
Yes. Changing arms, bushes or ball joints alters camber and caster. A proper alignment protects tyre life, restores straight-line stability, and ensures the Triton’s driver-assist systems work as intended.
