Parts for your 2019 Isuzu D-max-Strut mounts

2019 Isuzu D‑MAX strut-mounts

Based on manufacturer service information for the RT‑series Isuzu D‑MAX (2012–2019) and common workshop data used in Australia and New Zealand, the 2019 D‑MAX runs an independent double‑wishbone front end with a coil‑over shock absorber. That setup uses a rubberised upper support that bolts to the body — often called a strut mount, strut top, or top hat in parts catalogues — but it’s not a MacPherson strut with a rotating bearing. So yes, the vehicle does have a front shock/“strut” mount, but it doesn’t contain a steering pivot bearing like many passenger cars.

On a 2019 D‑MAX, the strut‑mount’s job is to secure the coil‑over to the chassis tower and soak up vibration and road harshness before it enters the cab. It keeps the top of the shock firmly located, helps the spring seat stay true under load, and reduces noise over corrugations. Because steering pivoting happens at the ball joints on this ute, the mount isn’t designed to rotate, instead, the rubber insulator provides isolation and a bit of compliance without free play.

Over time — especially with towing, bullbars, bigger tyres, rough tracks, or a lift — the mount’s rubber can harden, crack, or separate from the metal plate. Typical clues include:

• Clunks or creaks from the front over speed humps, potholes, or driveways
• Vibration or a dull thud on corrugations
• Visible perishing, splits, or “mushroomed” studs at the top tower
• Slight front‑end wander or imprecise steering feel on choppy surfaces

Good practice for D‑MAX servicing is to inspect the strut‑mounts any time the front shocks are out, at major services around the 80,000–150,000 km mark, and sooner if the ute sees regular off‑road work. Look for cracked rubber, torn bonding, loose fasteners, and elongation around the studs. If replacing front shocks or fitting a lift, consider new mounts at the same time — they’re relatively inexpensive and save doubling up on labour. Always tighten to the workshop‑manual torque specs and recheck after a short shakedown drive.

When choosing replacements, OE‑style rubber mounts keep NVH closest to stock. Some polyurethane options are firmer, which can sharpen steering feel but may add a touch of vibration on coarse‑chip roads. Replace mounts in pairs left/right, and book a wheel alignment afterwards — changes in ride height or compliance can nudge camber, caster, and toe on the D‑MAX’s double‑wishbone front end.

Popular questions about 2019 Isuzu D‑MAX strut‑mounts

Does a 2019 Isuzu D‑MAX actually have strut‑mounts?
Yes — the front coil‑over shock bolts to a rubberised upper mount commonly called a strut mount or top hat. It isn’t a MacPherson strut with a swivel bearing, steering pivoting happens at the ball joints, but the mount still plays a key role in location and noise isolation.

What are the signs the strut‑mounts are worn on a D‑MAX?
Listen for clunks or creaks over bumps, feel for harshness on corrugations, and check for cracked or separated rubber at the tower. You might also notice a slight wander or vibration through the floor on rough roads. Visual inspection during servicing is the easiest way to confirm.

Do I need a wheel alignment after replacing D‑MAX strut‑mounts?
Yes. Even though the mount doesn’t steer, swapping mounts or shocks can alter ride height and compliance, which can shift camber, caster, and toe. An alignment ensures the ute tracks straight and tyres wear evenly.
