Parts for your 2017 Isuzu D-max-Rack boots

2017 Isuzu D‑Max rack boots — what they do and when to replace them

Rack boots are fitted to the 2017 Isuzu D‑Max. Technical sources that confirm this include: the Isuzu TFR/TFS Workshop Manual (2012–2019, Steering section), which specifies a rack‑and‑pinion steering gear with bellows‑type dust boots on each end, and the Isuzu Electronic Parts Catalogue for the TFS‑series D‑Max, which lists “Boot, steering gear” as a service part for 2016–2019 build years. Industry catalogues for steering components also list rack boots for 2012–2020 D‑Max models, aligning with the factory documentation.

On this ute, the rack boots (also called bellows or gaiters) protect the inner tie‑rods and the steering rack from grit, water, and mud, and they help keep the right amount of grease where it belongs. That’s especially important for Aussie and Kiwi conditions — corrugations, beach runs, creek crossings, and red dust will shred an unprotected rack in no time. If a boot splits, sand and water can enter, grease can wash out, and if there’s a power‑steering internal seal leak, fluid can pool inside the boot and eventually escape.

As part of regular servicing on a 2017 D‑Max, a quick visual under the front end should include the rack boots. Look for cracks, perishing at the folds, loose or missing clamps, and any wetness that smells like power‑steering fluid. If there’s oil inside the boot or it’s torn, replace it straight away. Driving with a damaged boot can accelerate inner tie‑rod wear and lead to sloppy steering, uneven tyre wear, and a likely WOF/roadworthy fail.

• Check every service or 10,000–15,000 kilometres, more often if the vehicle sees off‑road or beach work.
• Replace in pairs if they’re aged — the opposite side won’t be far behind.
• Use quality boots and proper clamps, cable ties are a last resort and can loosen.
• After replacement, get a wheel alignment — the tie‑rod end usually needs to come off to slide the boot on.

DIY‑capable owners can swap boots with hand tools: support the vehicle safely, mark the tie‑rod end threads for reassembly, remove the tie‑rod end, slide off the old boot, clean the rack, lightly re‑grease the inner joint, then install the new boot with clamps. If there’s any sign of fluid inside the boot, have a technician check the rack’s inner seals — a new boot alone won’t fix an internal leak.

Popular questions about 2017 Isuzu D‑Max rack boots

Do all 2017 D‑Max models have rack boots?
Yes. The 2017 D‑Max uses a rack‑and‑pinion steering gear with bellows boots on each side, as outlined in the Isuzu TFR/TFS Workshop Manual and confirmed by the Isuzu Electronic Parts Catalogue. Both 4x2 and 4x4 variants are covered.

Can I keep driving with a torn rack boot?
It’ll drive, but it’s not wise. A torn boot lets in water and grit, which can chew out the inner tie‑rod and rack. If power‑steering fluid is leaking into the boot, you’ll also risk a bigger, pricier repair. Replace the boot promptly and inspect for internal leaks.

Do I need a wheel alignment after replacing rack boots?
Yes, recommended. The tie‑rod end usually comes off to fit the new boot, and even careful refitting can nudge toe settings. An alignment helps protect tyres and keeps the D‑Max tracking straight.
