Parts for your 2016 Mazda Cx-9-Rack boots

2016 Mazda CX-9 rack boots

Yes, the 2016 Mazda CX-9 does use rack boots. Technical references that confirm this include the Mazda CX-9 (TC) Workshop Manual under the Steering System section, where the “steering gear and linkage” exploded view shows protective bellows/boots at each end of the rack, and the Mazda Electronic Parts Catalogue (EPC), Steering Group, which lists a pair of “Boot, Steering Gear” items for the 2016-on CX-9. Popular aftermarket catalogues also list rack-and-pinion bellows kits for this model. So rack boots are absolutely relevant on the 2016 CX-9.

On this vehicle, rack boots (also called bellows or dust boots) sit over the inner tie rods and the rack ends, shielding the steering rack from grit, water and road grime. They help keep the inner joints lubricated and protect the rack seals on the electric power steering assembly. If a boot tears, contamination can quickly chew out inner tie rods or even the rack itself, turning a simple rubber boot job into a pricey steering repair.

As part of regular servicing in Australia and New Zealand conditions, it’s smart to inspect the rack boots at every service interval (about every 10,000 km or 12 months). A quick look for splits, oil seepage, or loose clamps can save a headache. If the vehicle has been used on gravel, through floods, or for a family road trip across the Nullarbor, give them an extra once-over.

• Grease or oil inside or around the boot
• Visible cracks, tears, or perishing
• Clamps missing or loose
• Clicking or play from inner tie rods
• Moisture or dirt tracked into the bellows

Replacement is straightforward for a competent tech: remove the tie rod end, slide off the old boot, clean the area, and fit a quality boot with new clamps. Don’t twist the bellows, and if the rack uses a breather or equalising hose between boots, make sure it’s reconnected so pressure can balance left to right. When a boot has failed, it’s good practice to replace both sides, check the inner tie rods for wear, and book a wheel alignment straight after the job so the tyres don’t scrub. Using OEM-spec boots and proper stainless clamps will give longer life, especially with our harsh UV and coastal conditions.

Does the 2016 Mazda CX-9 have rack boots?
Yes. The CX-9 (TC) uses an electric rack-and-pinion steering gear with protective bellows/boots at each end, as shown in the Mazda Workshop Manual and EPC listings for “Boot, Steering Gear.”

How often should rack boots be checked or replaced?
Have them inspected at every regular service (around 10,000 km/12 months). Replace immediately if cracked, perished, torn, or if clamps are loose. If one fails, consider replacing both sides and check inner tie rods.

Do they need a wheel alignment after replacing rack boots?
Yes. The tie rod end must be removed to swap boots, so a proper alignment is recommended to keep steering straight and protect the tyres from uneven wear.
