Parts for your 2017 Isuzu D-max-Steering bushes

2017 Isuzu D‑MAX steering bushes — what they do and when to replace

Technical sources confirm the 2017 Isuzu D‑MAX uses steering bushes. The Isuzu D‑MAX Workshop/Service Manual for the 2012–2019 generation specifies a hydraulic rack‑and‑pinion steering gear mounted to the chassis with rubber insulators (bushes). The Isuzu Electronic Parts Catalogue for the same model year lists these rack mounting insulators under the steering group. Aftermarket technical catalogues from well‑known brands that supply OE‑equivalent parts also list steering rack mounting bush kits specifically for 2012–2019 D‑MAX. So, steering bushes are relevant to this model.

On the 2017 D‑MAX, the steering bushes’ job is simple but crucial: they isolate the steering rack from the chassis to reduce vibration and noise while keeping the rack firmly located. When those bushes age, harden, crack, or deform (especially on utes doing corrugations, towing, or running heavier tyres), the rack can shift slightly under load. That shows up as vague on‑centre feel, knocking over bumps, tramlining, and sometimes uneven tyre wear.

As part of routine servicing, a good check is to have someone gently rock the steering wheel left–right while watching the rack where it mounts. Any visible rack movement relative to the crossmember, or clunks you can feel, points to tired bushes. Also look for perishing, splitting, or oil saturation (a power‑steering fluid leak can accelerate rubber deterioration). If one bush is gone, do the set.

• Typical lifespan varies with use, but 80,000–150,000 km is common, heavy off‑road work can shorten that.
• OEM rubber bushes keep NVH low and feel factory‑smooth. Quality polyurethane options sharpen response and last longer but may add a touch more vibration.
• Replace on condition, there’s no fixed interval, but don’t ignore noise or play.

Replacement is straightforward for a pro: support the rack, mark positions, remove the rack clamp bolts, swap bushes, and torque bolts to spec from the service manual. A wheel alignment is recommended afterward, especially if any steering or front‑end fasteners were disturbed. While there, inspect outer and inner tie rod ends and the lower column joint for wear. Keeping the system leak‑free (right fluid level and clean connections) helps the new bushes live a long life, particularly on Aussie and Kiwi roads with their fair share of corrugations and potholes.

If the steering feels loose, the wheel kicks back on bumps, or there’s a knock you can’t trace, fresh rack bushes can make a D‑MAX feel tight and confident again without blowing the budget.

Popular questions about 2017 Isuzu D‑MAX steering bushes

How can they tell if the D‑MAX’s steering bushes are worn?

Common signs include a dull knock over sharp bumps, vague on‑centre feel, and the steering wheel shimmying on corrugations. With the ute safely raised, an assistant can rock the steering wheel while a tech watches the rack mounts, any rack movement against the crossmember or visible cracking in the bush material suggests it’s time to replace them.

Do they need an alignment after replacing steering rack bushes?

Yes, it’s wise. While the tie rods may not be touched, the rack’s position can change slightly when new bushes go in. A post‑repair alignment ensures the steering wheel sits straight and the front tyres wear evenly.

Rubber or polyurethane — which suits a 2017 D‑MAX best?

For daily driving and touring, quality rubber keeps factory comfort and low NVH. For heavier off‑road use, towing, or larger tyres, polyurethane offers crisper steering and better durability. The trade‑off is a small increase in road feel and potential vibration through the cabin.
