Parts for your 2024 Mitsubishi Asx-Rack boots

2024 Mitsubishi ASX rack-boots: what they do and when to replace them

Based on technical sources — Mitsubishi Motors ASX service manual (Group 37: Steering), the Mitsubishi ASA electronic parts catalogue (steering gear assemblies and bellows/boots listings), and the Renault Captur (EU-market 2024 ASX equivalent) workshop manual for the electric power steering rack — the 2024 Mitsubishi ASX is fitted with rack-and-pinion steering that uses protective bellows commonly called rack-boots. So yes, rack-boots are relevant and used on the 2024 ASX.

On the ASX, rack-boots are the flexible bellows that seal the ends of the steering rack where the inner tie rods move. Their job is simple but crucial: keep dust, water, sand, and road grime out of the rack, and retain the light lubrication around the inner joints. When a boot splits, grit gets in, the inner tie rod and rack bushings wear fast, and moisture can corrode the rack. Leave it too long and a straightforward boot swap can turn into a pricey rack replacement.

During regular servicing, it’s smart to inspect the rack-boots every 10,000–15,000 km (or each service). Techs look for cracks, perishing, loose clamps, or grease tracks flung out onto the undertray. Vehicles that see corrugations, beach driving, flooding, or sharp kerb strikes deserve extra attention — those conditions are hard on the bellows.

If a boot is damaged, replace it promptly — ideally in pairs. A proper job involves removing the outer tie rod end, sliding off the old boot, cleaning the rack area, checking the inner tie rod for play, then fitting a correct-spec boot with quality clamps (not makeshift cable ties). Marking the tie-rod adjustment before removal helps the wheel alignment land close, but a final alignment is still recommended.

Good workshops also: use OE-style clamps to maintain a proper seal, avoid twisting the boot during install, verify inner tie rod torque and joint condition, and check for any water ingress. If there’s evidence of moisture or rust inside the boot, further inspection of the rack is warranted. Done right, it’s a quick, cost-effective job that prevents much bigger steering repairs down the track.

• Common signs a boot needs attention: visible splits, oil/grease spray near the rack ends, uneven tyre wear, light knock over bumps, or a loose boot clamp.
• Best practice: replace both boots, inspect inner tie rods, and carry out a wheel alignment.

Popular questions

How can someone tell if their 2024 ASX rack-boots are worn out?
They’ll often spot small cracks in the bellows, or notice grease flung onto nearby components. Steering may feel a bit knocky on bumps, and tyre wear can get a touch uneven. A quick look on a hoist during a routine service usually confirms it.

Can a split rack-boot be taped up to get by?
It’s not recommended. Tape or cable ties won’t keep water and grit out for long. A proper replacement boot with the right clamps is cheap insurance against inner tie rod and rack damage.

Do all 2024 ASX variants use the same rack-boots?
Trim levels can vary by market, but both the long-running AU/NZ ASX and the EU Captur-based ASX use EPS racks with bellows-style boots. Part numbers may differ by build code, so it’s best to match by VIN when ordering.
