Parts for your 2022 Mitsubishi Asx-Rack boots

2022 Mitsubishi ASX rack-boots: what they do and when to replace them

Based on technical sources, rack-boots are fitted to the 2022 Mitsubishi ASX. The Mitsubishi Motors Service Manual for ASX/RVR/Outlander Sport (Steering – Rack and Pinion section) illustrates bellows-type rack boots on both ends of the steering rack, and the Mitsubishi ASA electronic parts catalogue lists “steering gear bellows/boot” for the 2010–on ASX platform, which includes the 2022 model year. Major aftermarket catalogues also carry rack-boot kits for 2010–2023 ASX variants, confirming fitment.

On the 2022 ASX, the rack-boots (often called steering rack gaiters or bellows) sit over the inner tie rods at each end of the rack-and-pinion. Their job is simple but critical: keep water, dust and road grit out of the rack while retaining grease around the inner joints. Whether the ASX variant uses column-assist electric power steering or a hydraulic arrangement, the boots protect the same moving bits and stop premature wear, corrosion and that annoying gritty feel through the wheel.

For servicing, they’re a quick visual check under the bonnet and from underneath on a hoist. Look for splits, perishing, or grease sling on the inside of the front wheels. If a boot is torn, dirt and water can chew out the inner tie rod and rack seals fast, so don’t leave it—replace the boot and inspect the joint straight away. It’s smart to check them at every service interval or at least every 10,000–15,000 km, especially if the vehicle sees gravel roads or coastal air.

Replacement is straightforward workshop fare, but there are a few gotchas:

• Mark the tie-rod end position before removal to keep toe close, then get a wheel alignment afterwards.
• Use the correct clamps, cable ties can loosen and let dust in.
• Fit the boot without twisting, and ensure any breather feature isn’t blocked.
• If contamination is found, clean the rack area and re-grease the inner joint per the service manual.

Typical symptoms of a failed rack-boot include a light knock over bumps, vague steering, or visible grease and grime where it shouldn’t be. Fresh boots are cheap insurance compared with the cost of a steering rack.

Popular questions about 2022 Mitsubishi ASX rack-boots

How long do rack-boots last on a 2022 ASX?
In normal city and motorway use, they can last many years. In Aussie and Kiwi conditions with heat, UV and gravel roads, rubber can age faster. Regular inspections at service time will catch cracking early so they can be swapped before they leak or split.

Can a torn rack-boot fail a WOF or roadworthy?
Yes. A split or insecure steering gaiter is typically a fail item because it compromises steering integrity. If a boot is torn, replace it and check the inner tie rod and rack for wear. An alignment is recommended after the repair.

Do I need an alignment after replacing a rack-boot?
Even if the tie-rod end is counted and marked, a proper wheel alignment is the right move. It ensures toe is spot-on, steering centres nicely, and tyres don’t scrub.
