Parts for your 2016 Toyota Avensis-Rack boots

2016 Toyota Avensis rack boots: what they do and when to replace them

Yes, the 2016 Toyota Avensis (T27 series) uses steering rack boots. This is confirmed by Toyota’s Repair Manual for the Avensis T27 (Toyota TechDoc/TIS), which details removal and installation of the “rack boot” and boot bands during rack-end service, and by the Toyota Electronic Parts Catalogue (EPC) that lists “Boot, Steering Rack” and matching clamps for T27 Avensis models. Even though the Avensis of this era uses electric power steering, it still has a rack-and-pinion with bellows-type boots to protect the rack bar and inner tie rod joints.

On a 2016 Avensis, rack boots (also called gaiters) are flexible bellows that seal out water, dust, and road grit while keeping the correct grease around the inner tie rod and rack bar. They’re critical for smooth steering, preventing corrosion, and stopping premature wear of the inner joints and rack bushes. A split or dislodged boot can let in grit that chews through the joint quickly, leading to play, knocks over bumps, and a potential Warrant of Fitness fail in NZ.

As part of routine servicing, they should be visually checked every service (or at least every 10,000–15,000 km). Look for cracks in the folds, grease sling on the inner guard, loose or missing boot bands, or moisture and rust inside the bellows. If there’s any doubt, replace the boot pair promptly.

Replacement is straightforward for a trained tech: the outer tie rod end is removed, the old bands are cut, the boot is slid off, the rack bar is cleaned and re-greased to spec, then a new boot and new bands are fitted with the bellows untwisted and seated in the grooves. The tie rod end is refitted and a wheel alignment is recommended because toe can shift even if thread counts are marked. Use proper crimp bands rather than cable ties, and avoid twisting the boot as that can shorten its life.

Quality OEM-equivalent boots last well, but harsh conditions can shorten life, so it’s smart to inspect after off‑road trips or flood driving. Keeping these little bellows healthy is cheap insurance for a much more expensive steering rack.

• Signs it’s time: cracked bellows, perished rubber, loosened bands, visible grit or rust inside, new steering play or knocks.
• Good practice: inspect at every service, replace in pairs, align wheels after work, and never lift or tow from the tie rods.

FAQs

Are rack boots the same as the tie rod end dust boots on a 2016 Avensis?

No. Rack boots are the large bellows that cover the rack bar and inner tie rod area. The outer tie rod end has its own small dust boot. They do different jobs and fail in different ways, but both need to be intact to keep the steering in good nick.

When a rack boot splits, it exposes the inner joint and rack to grit and water, when an outer tie rod boot splits, it compromises just that ball joint. Both can lead to play and inspection failures if ignored.

Is it OK to drive with a torn rack boot?

It’ll usually drive, but it’s not a good idea for long. A torn boot lets in grit that can quickly wear the inner tie rod and rack bar, turning a simple boot job into a rack replacement.

If a split is spotted, book it in soon. Many NZ WOF inspectors will fail a visibly split or unsecured steering gaiter, so sorting it promptly saves hassle and bigger bills.

Do I need a wheel alignment after replacing rack boots?

Yes, a wheel alignment is recommended. The job typically involves removing the outer tie rod end, even if threads are marked, toe can shift a touch.

Getting the alignment checked restores proper tyre wear and steering feel, and it’s cheap peace of mind after any steering work.
