Parts for your 2023 Mitsubishi Triton-Rack boots

2023 Mitsubishi Triton rack-boots: what they do and when to replace them

Technical verification: The 2023 Mitsubishi Triton (MR series) uses a rack-and-pinion steering gear with bellows-style boots on each end of the rack. This is documented in the Mitsubishi L200/Triton MR Service Manual (Steering/Power Steering section) and reflected in the Mitsubishi electronic parts catalogue (ASA), which lists left and right “steering gear boots/gaiters” for MR models. Major aftermarket catalogues for MQ/MR Triton also supply rack boots, confirming fitment on 2023 vehicles.

So yes, the Triton does have rack-boots. These flexible rubber gaiters seal the ends of the steering rack, shielding the inner tie-rod joints and rack bar from water, mud, and grit. On a ute that often sees job sites, gravel roads, and the odd creek crossing, those boots are the first line of defence against premature wear of the steering gear.

As part of routine servicing, it’s smart to give the rack-boots a quick once-over. Look for splits, perishing, oil swelling, loose or missing clamps, and any evidence of sand or fluid under the boot. If a boot is torn, contaminants can chew out the inner tie-rod and the rack seal, leading to play at the wheel, clunks over bumps, uneven tyre wear, and—on hydraulic systems—potential power-steering fluid leaks.

Replacement is straightforward for a trained tech: remove the front wheel, disconnect the tie-rod end from the knuckle, mark or measure the tie-rod adjustment, slide off the old boot and clamps, inspect and clean the rack area, then fit a quality boot with correct clamps and orientation. A light smear of suitable grease on the inner tie-rod ball can be appropriate—don’t pack the boot with grease and don’t kink or twist the bellows. After refit, the toe setting should be checked, a quick alignment is often recommended.

How often should it be checked? At every service is ideal, or at least every 10,000–15,000 km, and immediately after heavy off-road or floodwater use. Given Australia and New Zealand’s harsh UV and off‑road conditions, boots can harden and crack sooner than expected. If one side fails, it’s common sense to replace both sides with OE or high-quality aftermarket parts. It’s a small job that can save a very pricey steering rack down the track.

• Key signs of trouble: grease or fluid weeping, visible splits, steering play, or uneven tyre wear.
• Best practice: inspect each service, replace in pairs, and get an alignment after replacement.

Popular questions

How often should rack-boots be replaced on a 2023 Triton?

There’s no fixed interval—replace on condition. Have them inspected every service. In tougher Aussie and Kiwi conditions, plan on replacement at the first sign of cracking, swelling, or a split, rather than waiting for steering issues to show up.

What happens if a rack-boot splits and it’s left alone?

Dirt and water will enter, accelerating wear of the inner tie-rod joint and rack seals. That can lead to clunks, vague steering, uneven tyre wear, and potentially a leaking steering rack—turning a cheap boot job into an expensive rack overhaul.

Can a DIYer replace Triton rack-boots at home?

It’s doable with stands, basic tools, a tie-rod separator, and careful measurement of the tie-rod adjustment. The critical bit is refitting without twisting the boot and then checking alignment. If unsure, a workshop can knock it over quickly and safely.
