2013 Mazda CX-5 rack boots — what they do and when to replace them
Based on Mazda’s KE-series Workshop Manual (Steering System: Steering Gear and Linkage) and Mazda’s electronic parts catalogue for the 2012–2016 CX-5, the 2013 Mazda CX-5 uses a rack-and-pinion steering gear fitted with dust boots (rack boots/bellows) on each end. Even though this model runs electric power steering assist, the physical steering rack still relies on rack boots. So, rack boots are absolutely relevant and used on the 2013 CX-5.
On a 2013 CX-5, rack boots are the concertina-style rubber bellows that seal the ends of the steering rack and cover the inner tie rods. Their job is to keep water, grit, and road splash out of the rack housing while allowing full steering movement. By protecting the rack gear and the inner tie rod joints, they help prevent corrosion, premature wear, and that gritty, notchy steering feel no one wants.
Because the KE-series CX-5 uses electric power steering, the boots don’t contain hydraulic fluid. If a boot splits, owners won’t see power steering fluid leaking, but moisture and dust can creep in and quietly chew out the inner tie rod and, in worst cases, the rack itself. That’s why regular checks matter.
- Inspection: Have the rack boots looked at during routine services (every 10,000–15,000 km or at least annually). A quick check on a hoist will spot cracks, splits, loose clamps, or oil/grease weeping that suggests a worn inner tie rod.
- Replacement triggers: Any split, perished rubber, or a boot that’s gone hard or swollen. If contamination has gotten inside, consider replacing the inner tie rod as well.
- Fitment tips: Use OE-style clamps rather than generic zip ties, sit the boot without twisting, and equalise air pressure in the bellows before clamping. Once any steering component is changed, a wheel alignment is smart practice.
- Longevity: Quality boots and proper clamps last longer, especially in Aussie and Kiwi conditions with heat, rain, and gravel roads.
Left too long, a torn boot can turn into a bigger bill—think inner tie rod play, uneven tyre wear, and potentially a damaged rack. Keeping the boots intact is cheap insurance for smooth, precise steering on a KE CX-5.
Popular question: What are the signs the rack boots need replacing on a 2013 CX-5?
Look for visible splits or cracks in the rubber, loose or missing clamps, or dirt and moisture inside the boot. A light grease misting can hint at inner tie rod wear. If steering starts to feel notchy or there’s uneven tyre wear, it’s time for a closer look.
Popular question: Do rack boots on the CX-5 contain fluid?
No. The 2013 CX-5 uses electric power steering, so the boots don’t hold hydraulic fluid. They’re purely dust boots that keep contaminants out. Any wetness usually points to grease from the inner tie rod or contamination, not power steering fluid.
Popular question: How often should CX-5 rack boots be checked or replaced?
Have them inspected at every service or at least annually. There’s no fixed replacement interval—change them when they’re cracked, split, perished, or contaminated. After any boot or inner tie rod work, organise a wheel alignment.
