Parts for your 2018 Toyota Corolla-Rack boots

2018 Toyota Corolla rack boots: what they do and when to replace them

Yes, a 2018 Toyota Corolla is fitted with steering rack boots. Technical references that show this include the Toyota Repair Manual for Corolla models with Electric Power Steering (EPS), where the rack-and-pinion assembly is depicted with bellows-style rack boots and single‑use boot clamps, and the Toyota Electronic Parts Catalog (EPC) for AU/NZ-delivered 2018 Corolla variants, which lists a “Boot, Steering Rack” for both sides of the rack. General service guides such as Haynes/Max Ellery for 2014–2019 Corolla also illustrate the same boots and clamps.

On an Aussie or Kiwi 2018 Corolla (ZRE172/ZRE182 sedans and hatches, and early E210 introductions), those rack boots are the accordion-looking rubber bellows at each end of the steering rack. Their job is simple but critical: keep dust, water and road grit out of the inner tie rods and rack bar, while holding the right amount of grease around those moving parts. Even though the Corolla uses EPS (so there’s no hydraulic fluid in the rack), the boots still matter heaps for longevity and steering feel.

During routine servicing, a quick visual check of the rack boots should be on the list. They’re not a time-based replacement item, but they do age from heat, flexing and road grime. If a boot is torn, split, loose on its seat, or flinging grease, it’s time to replace it. Driving with a ripped boot can let moisture in, leading to inner tie rod wear and possible corrosion on the rack bar—issues that can escalate into play in the steering and uneven tyre wear.

Good practice on a 2018 Corolla rack boot job includes:

• Use quality, model-appropriate boots and new single-use clamps (ear or crimp style as specified in the Toyota RM).
• Clean and regrease the inner tie rod ball socket if contamination is found, replace the inner tie rod if there’s play or roughness.
• Seat the boot correctly on the rack housing and tie rod, orienting the vent as per the manual so it doesn’t trap water.
• Mark tie-rod positions before removal and get a proper wheel alignment afterwards—toe will almost always shift.
• Inspect both sides, if one boot has failed, the other may not be far behind.

Owners will notice the benefits as simple peace of mind: consistent steering feel, reduced chance of inner tie rod knock, and protection for the rack so it keeps doing the hard yards for years.

Does a 2018 Toyota Corolla have steering rack boots?

It does. Both ends of the Corolla’s rack-and-pinion steering use bellows-style boots to shield the rack bar and inner tie rods. This applies to EPS-equipped models sold in Australia and New Zealand. They’re shown in Toyota’s Repair Manual and listed in the Toyota EPC as “Boot, Steering Rack.”

How often should rack boots be checked or replaced on a 2018 Corolla?

They’re inspection items at every service (roughly every 10,000–15,000 km). Replace them if torn, split, loose, or contaminated with grit. There’s no strict time or kilometre interval—condition rules. If a boot has failed, also assess the inner tie rod for wear.

Do you need a wheel alignment after changing rack boots?

Yes. Removing or loosening the outer tie-rod end and lock nut can alter toe. Even if counted turns were used, a proper alignment is the safe bet to avoid uneven tyre wear and off‑centre steering.
