Parts for your 2023 Mitsubishi Triton-Suspension bushes

2023 Mitsubishi Triton suspension bushes — what they do and how to look after them

Suspension bushes are absolutely used on the 2023 Mitsubishi Triton (MR series). Technical sources that detail their fitment include the Mitsubishi Triton MR Workshop Manual (Front Suspension Group 33A and Rear Suspension Group 33B), the Mitsubishi ASA electronic parts catalogue (control arm, stabiliser bar, and leaf spring bush listings), and leading aftermarket catalogues (e.g., SuperPro and Nolathane) that publish specific bush kits for the MR Triton’s front upper/lower control arms, front stabiliser bar, and rear leaf spring eye and shackle locations. These references confirm the Triton’s double-wishbone front end and leaf-sprung rear axle both rely on multiple rubber/poly bushes.

On a 2023 Triton, suspension bushes are the quiet achievers. Pressed into control arms, leaf spring eyes and shackles, and cradling the front stabiliser bar, they isolate noise and vibration, keep alignment steady, and let the arms and springs pivot smoothly. That’s how the ute feels planted on corrugations, tracks straight when towing, and doesn’t racket over potholes.

Over time, heat, UV, red dust, oils, and big hits from off‑road work harden or crack the rubber. When that happens, the front end can feel vague, the rear can steer around under load, and tyres can start to scrub. On the Triton, common tell‑tales are clunks over speed bumps, steering wander, uneven tyre wear, and squeaks from the rear shackles after rain or a wash.

For servicing, it pays to inspect bushes at least every 20,000 km or annually—more often if the ute tows, carries a canopy and tools, or sees beach and outback work. Look for perished rubber, splits, displaced sleeves, and oil contamination (leaking shocks or diff oil can accelerate failure). When one side is worn, replace in axle pairs to keep handling balanced. After any front control arm bush replacement, book a wheel alignment—camber/caster will shift as soon as fresh bushes go in.

• OEM rubber keeps it comfy and quiet, great for daily and fleet use.
• Polyurethane tightens steering and lasts longer off‑road, but can transmit a bit more road feel, use the correct grease and re‑lube as recommended.
• Always torque bush bolts at normal ride height to avoid pre‑loading the rubber.
• Don’t forget stabiliser bar D‑bushes and links—cheap parts that cure a lot of knocks.

A tidy set of bushes makes a Triton feel newer, tracks better with a trailer, and protects tyres and shocks—worth doing before the big trip across the Nullarbor or the next run up to the bach.

How long do Triton suspension bushes last?

In typical NZ and Aussie use, factory rubber bushes often last 80,000–150,000 km. Heavy towing, corrugations, beach work, and lifted suspensions can shorten that. Regular inspections pick up cracks and movement well before they become a safety or tyre-wear issue.

Rubber or polyurethane bushes for a work-and-weekend Triton?

Rubber keeps it quiet and comfy—ideal for commuting and mixed duties. Polyurethane sharpens steering and usually handles heat and load better off‑road, at the cost of a touch more vibration. For a touring/towing setup, many owners run poly in the rear leaf spring eyes/shackles and quality rubber up front to balance comfort and control.

Do they need a wheel alignment after bush replacement?

Yes—any front control arm bush work changes camber and caster, so an alignment is essential. It’s also smart to check rear thrust angle after leaf spring bush or shackle work to make sure the ute tracks straight and the steering wheel sits centred.
