Parts for your 2015 Toyota Avensis-Rack boots

2015 Toyota Avensis rack boots (rackboots): purpose, servicing and replacement

Yes, the 2015 Toyota Avensis (T27) is fitted with steering rack boots—also called rackboots or steering rack gaiters—on both sides of its rack-and-pinion steering. This is confirmed by Toyota’s Avensis T27 Repair Manual (Steering – Steering Linkage/Gear sections) and the Toyota Electronic Parts Catalogue, both of which list the bellows-style “boot” for the steering gear. Regulatory guides used in Australia and New Zealand, such as the NZTA Vehicle Inspection Requirements Manual and the DVSA MOT Inspection Manual used widely for reference, also treat split or insecure steering gaiters as a safety defect, underscoring that the Avensis uses them and that their condition matters.

On this Avensis, the rack boots seal the inner tie rods and the ends of the steering rack, keeping dust, water and road grit out while retaining the light lubricant film that protects the rack. Many 2015 Avensis models use electric power steering, even so, the rack still relies on intact boots to prevent wear, corrosion and play that can lead to vague steering and uneven tyre wear.

For everyday servicing, they’re worth a quick look at each service interval (around 10,000–15,000 km) or any time the front undertray is off. Replace a boot if it’s cracked, split, oil-soaked, loose on the rack or tie rod, or if there’s a tell-tale click, knock or stiffness when turning.

• Common signs of trouble: grease or oil weeping from a boot, visible splits, dirt inside the bellows, or accelerated inner-edge tyre wear.
• If hydraulic power steering is fitted on a variant, fluid inside the boot can indicate an internal seal leak, for the Avensis with electric assist, fluid inside usually means contamination from elsewhere.

When replacing, use a genuine Toyota boot or a quality equivalent with the right pleat length and bore. Renew the clamps, and avoid twisting the bellows during fitment. Mark the outer tie-rod position or count the turns off to help preserve toe, an alignment check afterwards is still smart practice. Apply only the light lubricant specified in the manual—overpacking a boot invites dust retention. If a boot has been torn for a while, inspect the inner tie rod for play and the rack for corrosion before reassembly.

Keeping the Avensis’ rackboots in good nick is simple insurance: sharper steering feel, longer rack life, and smoother WOF/regos without surprises.

Does the 2015 Toyota Avensis have rack boots?

Yes. The T27 Avensis uses rack-and-pinion steering with a bellows boot on each side to protect the inner tie rods and rack ends. Toyota’s T27 Repair Manual and Parts Catalogue list these boots, and inspectors in AU/NZ treat damaged steering gaiters as a defect, so they’re definitely part of the car.

How often should rack boots be replaced on a 2015 Avensis?

They’re not a scheduled replacement item, they’re replaced on condition. Inspect at each service or tyre rotation. In typical Aussie and Kiwi conditions they can last many years, but UV, gravel roads and age can crack them. Change them as soon as splits, looseness or contamination are seen, and get an alignment check afterwards.

Can a home mechanic replace Avensis rack boots?

Yes, if they’re comfortable removing the outer tie-rod end. Expect roughly 1–2 hours per side. The key is not twisting the new boot, using the correct clamps, and preserving toe by marking/counting turns. If there’s any play at the inner tie rod, replace that at the same time and book an alignment.
