Parts for your 2014 Mazda Premacy-Rack boots

2014 Mazda Premacy rack-boots: what they do and when to replace them

Based on Mazda’s workshop literature for the Premacy/Mazda5 (CW) steering system and the Mazda Electronic Parts Catalogue (EPC, Group 32 – Steering, sub-group “Boot, steering gear”), the 2014 Mazda Premacy uses a rack-and-pinion steering gear with a protective bellows-style boot on each side. Aftermarket parts catalogues for the same model years also list direct-fit rack boots for this vehicle. So yes—rack-boots are absolutely relevant and fitted on the 2014 Mazda Premacy.

The rack-boots on a 2014 Mazda Premacy are there to keep grit, water, and road grime out of the inner tie rod joints and rack seals, while holding the right amount of grease where it matters. Each side of the steering rack has a flexible bellows that moves as the wheels steer, creating a barrier that helps the rack last longer and steer smoothly. If a boot splits, the inner joint can dry out and wear, and the rack itself can cop corrosion or seal damage. Whether the car’s running hydraulic or electric assist, a torn boot is bad news.

As part of regular servicing, it’s smart to eyeball the rack-boots whenever the vehicle is on a hoist—think at each service or WOF. Tell-tale signs they’re due include visible cracking, grease flung around the subframe, moisture or rust tracks inside the boot, a light clunk on lock, or uneven tyre wear. If one side has failed, the other is often not far behind.

Replacement is straightforward for a trained tech: remove the tie rod end, slide off the old boot, clean the area, then fit a quality OEM or reputable aftermarket boot with proper clamps. Avoid cable ties—use the correct band clamps so the seal is even. The boot shouldn’t be twisted when installed, and any required breather or equalisation is maintained so it doesn’t balloon. It’s a good time to check inner tie rod free play and the rack seals while the area’s open.

Because the tie rod end is disturbed, a wheel alignment is recommended straight after. That’ll keep the Premacy tracking straight and protect tyres. If the car’s often driven on gravel roads or through floodwater, consider more frequent inspections—boots cop a harder life in those conditions. Catching a split early can save the rack and a heap of coin down the track.

• Inspect rack-boots at every service/WOF.
• Replace at the first sign of cracking, grease loss, or moisture ingress.
• Use correct clamps and follow alignment with a professional wheel alignment.

Popular questions

Does a 2014 Mazda Premacy have rack-boots?
Yes. The Premacy (Mazda5) uses a rack-and-pinion setup with a bellows-style boot on each side of the steering rack to protect the inner tie rod joints and rack seals.

How often should rack-boots be checked or replaced?
Check them at every service or WOF. Replace them as soon as cracks, tears, or grease leakage are seen, or if there’s moisture/rust inside the boot. There’s no fixed kilometre age—condition is key.

Do I need a wheel alignment after changing rack-boots?
Yes. Removing the tie rod end to fit a new boot will almost always affect toe. A post-repair alignment keeps the steering true and protects tyre life.
