Parts for your 2019 Mitsubishi Outlander-Rack boots

2019 Mitsubishi Outlander rack-boots: what they do and when to replace them

Based on technical references including the Mitsubishi Outlander (ZJ–ZL, covering 2013–2020) Workshop Manual – Steering section, and the Mitsubishi ASA Electronic Parts Catalogue, the 2019 Mitsubishi Outlander is fitted with rack-and-pinion steering that uses protective bellows (often called rack-boots or steering rack gaiters) on each end of the rack. So yes—rack-boots are relevant and used on this model, even though the Outlander runs electric power steering.

On a 2019 Outlander, the rack-boots seal the rack ends and inner tie-rods from water, dust, and road grit, while keeping the factory grease where it belongs. They also help protect the rack seals and the inner joints from premature wear. A torn or loose boot can let in moisture, leading to corrosion on the rack shaft and play in the inner tie-rod—issues that can snowball into steering noise, vague feel, and a failed WOF or roadworthy.

For servicing, it’s smart to have the rack-boots inspected at every routine service or at least every 10,000–15,000 km, especially if the Outlander sees gravel roads, beach trips, or regular towing. Look for splits, perishing, missing clamps, or grease flung around the inner wheel arch.

• Replace rack-boots immediately if they’re cracked, split, oil/grease-soaked, or if clamps are missing or loose.
• Use quality EPDM/neoprene boots and proper stainless clamps—skip cable ties.
• Plan for a wheel alignment after the job, even careful removal can nudge toe settings.
• If one boot has failed, consider doing both sides to keep wear even.

Replacement usually involves disconnecting the outer tie-rod end, sliding the old boot off, cleaning the area, and fitting the new boot with fresh clamps. Mark tie-rod positions or count turns to help preserve alignment, but still book an alignment afterwards for peace of mind and even tyre wear. Avoid blasting the boots with a pressure washer and check them after any off-road stint.

Because the Outlander’s power assist is electric, you won’t see power steering fluid inside the boots, any contamination is typically water, mud, or grease from the inner joint. Catching a dodgy boot early is far cheaper than dealing with an inner tie-rod or rack replacement down the track.

Popular questions about 2019 Mitsubishi Outlander rack-boots

Do 2019 Outlanders actually have rack-boots?
Yes. Technical documentation (Mitsubishi ZJ–ZL Workshop Manual and ASA EPC) shows a rack-and-pinion steering gear with bellows-style boots on both ends. Even with electric power steering, the boots protect the inner tie-rods and rack from grit and water.

How often should rack-boots be replaced?
They’re not a fixed-interval item. Inspect them at every service, replace as soon as they’re cracked, split, or the clamps are loose. Many last years, but harsh conditions can shorten their life.

Do I need a wheel alignment after replacing rack-boots?
It’s highly recommended. The job usually involves disturbing the tie-rod end. Even if you count turns or mark threads, a proper alignment protects tyre wear and steering feel.
