Parts for your 2013 Isuzu D-max-Steering bushes

2013 Isuzu D‑MAX steering bushes

Yes, steering bushes are relevant and fitted to the 2013 Isuzu D‑MAX. Technical references including the Isuzu D‑MAX (RT‑series, 2012–2016) workshop manual (Steering – rack‑and‑pinion section) and the Isuzu Electronic Parts Catalogue list rubber “steering gear mounting” bushes for the rack. Major aftermarket catalogues (e.g., SuperPro and Nolathane) also offer steering rack mount bush kits specifically for the 2012–2016 D‑MAX/Colorado platform, confirming their use on this model.

On the 2013 D‑MAX, the steering bushes cradle the rack and pinion in the crossmember. Their job is twofold: keep the rack located so steering geometry stays true, and soak up noise, vibration and harshness from corrugations, potholes and off‑road work. When these bushes soften, split or oval out, the rack can shift under load, which makes the steering feel vague on‑centre, adds clunks over bumps, and can even nudge the ute off line under braking.

For owners who tour, tow or hit rough roads, it’s smart to treat steering bushes as a consumable. A quick inspection every service (or 10,000–15,000 km) pays off: look for cracking, oil swelling, shiny fretting marks or visible rack movement while an assistant rocks the steering wheel. Typical replacement falls somewhere between 80,000 and 150,000 km, sooner if running heavy tyres, lift kits or doing plenty of gravel work.

• Common symptoms of worn bushes:
  • Clunk or knock through the column on bumps or when parking
  • Steering wander or delay when changing lanes
  • Uneven or accelerated front tyre wear
  • Visible rack shift when the wheel is rocked at standstill

Replacement is straightforward for a workshop: support the rack, remove the mount bolts, swap bushes, then torque the hardware to the factory spec with the vehicle at ride height. An alignment check afterwards is a good idea, especially if the old bushes were badly flogged out. Rubber keeps things quiet and comfy, quality polyurethane tightens steering feel and resists oil and heat, but can pass a touch more road feel into the cabin. Either way, use reputable parts and re‑torque after a short shakedown.

DIYers should avoid hanging the rack off the hoses, keep the mount bolts clean, and match orientation marks on eccentric bushes if fitted. If there’s any doubt about play in inner/outer tie‑rod ends or lower control arm bushes, get those checked at the same time to restore the D‑MAX’s tidy, predictable steering.

Popular questions about 2013 Isuzu D‑MAX steering bushes

Do 2013 D‑MAX utes use rack bushes or an idler arm bush?
The 2013 D‑MAX runs a hydraulic rack‑and‑pinion setup, so there’s no idler arm. It uses steering rack mounting bushes that secure the rack to the crossmember and isolate vibration.

How often should steering bushes be replaced?
There’s no fixed interval. Inspect every service and replace when there’s cracking, oil‑swelling, excessive softness, or rack movement on a steering shake test. Many see replacement somewhere between 80,000 and 150,000 km, sooner with heavy off‑road use.

Will worn steering bushes fail a WOF/RWC?
They can. Excessive play or visible rack movement, clunks, or degraded bushes may lead to a fail. If you’re chasing a vague steering feel or uneven front tyre wear, getting the bushes checked before inspection is a smart move.
