2017 Mitsubishi Eclipse Cross Rack Boots: What they do and when to replace them

Rack boots are fitted to the 2017 Mitsubishi Eclipse Cross. This is confirmed by Mitsubishi Motors’ Eclipse Cross (GK) Service Manual, Group 37: Steering (electric power steering rack-and-pinion with bellows), and the Mitsubishi ASA/EPC for GK1W/GK2W, which lists left/right “steering gear bellows” (often called rack boots or gaiters). So, yes—rack boots are absolutely relevant on this model.

On a 2017 Eclipse Cross, the rack boots are the flexible bellows sitting at each end of the steering rack. Their job is simple but critical: keep dust, water, and grit out of the rack housing and the inner tie-rod joints, and keep the factory grease in. Even though the Eclipse Cross uses electric power steering (not a hydraulic rack), those bellows still matter, once they split, moisture and road grime can work their way into the inner joints and rack bushings, leading to steering play, noise, corrosion, and expensive rack damage.

As part of regular servicing, a quick visual check of the boots is smart—look for cracks, splits, oil or grease sling on the inside of the wheel, or loose/missing clamps. If a boot is torn, replace it straight away. It’s a relatively small job that can save a rack. Most workshops will recommend doing both sides if one has perished, and using OE-style stainless clamps rather than cable ties. Because the tie-rod end is usually disturbed during boot replacement, a wheel alignment is recommended immediately afterwards to avoid uneven tyre wear and off-centre steering.

In Aussie and Kiwi conditions—heat, UV, and plenty of road spray—rubber can age quickly. Inspect the rack boots at every service or at least every 10,000–15,000 km, and sooner if the vehicle sees gravel roads, beach launches, or frequent wet weather. If your Eclipse Cross is going for a WOF/roadworthy, note that a torn steering rack boot is typically a fail item, so it’s well worth catching early.

• Telltale signs a rack boot needs attention: visible cracks or tears, grease on the inside of the rim, knocking or play in the steering, or a musty, gritty feel when turning lock-to-lock.
• Best practice: replace damaged boots promptly, use quality clamps, and book an alignment after the job.

How often should rack boots be replaced on a 2017 Eclipse Cross?

There’s no set kilometre interval—boots are replaced on condition. Have them inspected at each service. In harsher use (coastal, gravel, heavy rain), check more often. If there’s any cracking, splitting, or loose clamps, sort it before grit reaches the rack and inner tie-rod joints.

Plenty of owners go years without needing boots, but once rubber ages or gets nicked by debris, they can fail quickly, so proactive checks pay off.

Will a torn rack boot fail WOF/roadworthy in AU/NZ?

Yes, a torn or missing steering rack boot is commonly a fail item. It’s considered a safety-related defect because it can lead to accelerated wear in the steering gear. Replacing the boot and securing it with proper clamps will usually get you back to pass, provided there’s no resulting play in the steering.

Do you need a wheel alignment after replacing a rack boot?

In most cases, yes. Boot replacement typically involves removing or disturbing the tie-rod end, which can alter toe. A proper alignment ensures straight tracking, even tyre wear, and a centred steering wheel. It’s a quick add-on that protects tyres and keeps the Eclipse Cross driving spot on.
