Parts for your 2013 Mazda Premacy-Rack boots

2013 Mazda Premacy rack-boots — what they do and when to replace them

Rack-boots are absolutely fitted to the 2013 Mazda Premacy (CW series). Technical documentation — including the Mazda Workshop Manual for the Premacy/Mazda5 CW (Steering System: Steering Gear and Linkage) and the Mazda Electronic Parts Catalogue for the CW chassis — shows a rack-and-pinion steering gear with left and right “steering gear dust boots” (often called rack-boots or gaiters). So yes, they’re relevant on this model.

On this Premacy, the rack-boots are the flexible bellows that seal each end of the steering rack. Their job is simple but crucial: keep water, grit and road muck out, and keep grease around the inner tie rod joints. That protection stops corrosion and wear on the rack bar and inner tie rod ball joints, which in turn keeps the steering light, quiet and precise. Whether the car runs hydraulic or electric assist, the boots are still doing the same protective work.

Australian and New Zealand conditions can be tough on these boots — heat, UV, gravel, coastal salt and muddy roads all speed up cracking. A split boot lets contaminants chew out the inner joint and can even let leaking steering fluid or moisture sit where it shouldn’t. It’s also something that can draw attention at WOF/rego time.

• Check at each service (about every 10,000–15,000 km) or any time a knock, squeak or vague steering feel appears.
• Look for cracks, splits, loose or missing clamps, or grease/oil weeping from inside the boot.
• If one boot has failed, plan on replacing both sides — the other is usually not far behind.

Replacement is straightforward for a pro: outer tie rod end off, old boot and clamps off, inspect and clean, then new boot on with fresh quality clamps. Avoid twisting the bellows as it goes on, and make sure it’s not stretched at full lock. Don’t overpack with grease, only the inner ball joint needs the specified amount. Use proper ear-type or OEM-style clamps rather than bulky worm-drive hose clamps that can foul on lock. After any tie rod or boot work, a wheel alignment is a smart move to keep tyre wear even and the steering wheel straight.

Choosing decent EPDM or neoprene boots pays off — they tend to last longer in our climate. If there’s fluid inside a boot, that can point to a leaking rack seal, which is a separate fix worth tackling early before it gets spendy.

Popular questions about 2013 Mazda Premacy rack-boots

What are the signs a rack-boot is split on a 2013 Mazda Premacy?
Tell-tales include visible cracks or tears in the bellows, grease flung onto the inner wheel or lower control arm, a light knock over bumps, or a slight notchiness when turning the wheel. In wet weather or on gravel, a torn boot can let water and grit in, which quickly accelerates inner tie rod wear.

Do you need a wheel alignment after replacing rack-boots?
Yes, it’s best practice. Even if the tie rod length is carefully marked, removal and refit can nudge toe settings. A quick alignment keeps the steering wheel centred and protects your tyres from premature wear.

How often should the rack-boots be checked or replaced?
Have them inspected at every service or at least every 10,000–15,000 km. There’s no set replacement interval — good boots can last years — but if there’s cracking, loose clamps, or contamination inside the boot, replace them promptly to protect the rack and inner joints.
