Parts for your 2018 Toyota Avensis-Steering bushes

2018 Toyota Avensis steering bushes — are they actually a thing?

Short answer: not really. On the 2018 Toyota Avensis (T27 series), “steering bushes” aren’t a separate, serviceable part. Technical references including Toyota’s Service Information (TIS) Repair Manual for the T27, the Toyota Electronic Parts Catalogue (EPC) for ZRT272/ADT271 variants, and common aftermarket data (Autodata, Haynes Avensis 2009–2018) all show an electric power steering (EPS) rack-and-pinion assembly where the rack mounts and internal supports are integral to the unit. There’s no separate Toyota part listing for rack-mount bushes, and there’s no workshop procedure to replace them—if there’s play or noise from the rack supports, the specified fix is to replace the complete steering gear assembly.

Why’s that the case? With EPS, the assist motor and control gear sit on or within the rack housing. To keep steering feel tight and the alignment between the motor, torque sensor and rack precise, the “bush” functions are designed into the housing and subframe interface. They’re engineered as non-serviceable to maintain calibration and NVH performance. The steering column on these cars uses bearings and a collapsible shaft with universal joints, again, no discrete column “bush” is provided as a routine service item in Toyota documentation.

So if someone’s chasing vague steering, clunks, or a shimmy on a 2018 Avensis, the smart move is to look at the parts Toyota actually intends to be serviced:

• Inner and outer tie rod ends (rack ends and rod ends)
• Front lower control arm bushes and ball joints
• Stabiliser (sway bar) link rods and D‑bushes
• Front strut top mounts/bearings and wheel bearings
• Tyres (wear and pressures) and wheel alignment

Technicians can confirm all this in Toyota’s TIS Repair Manual (Avensis T27 EPS – Steering Gear and Linkage section) which provides inspection steps for free play and noise, then directs replacement of the steering gear assembly where bush-type support play is detected. The Toyota EPC diagrams for the same model list the “steering gear assembly,” brackets and fasteners, but no standalone rack-mount bush part numbers, reinforcing that “steering bushes” aren’t a separate fitment on this vehicle. Haynes and Autodata mirror that guidance—bushings within the rack are not supplied, renew the complete unit if worn.

Bottom line for owners: if a workshop quotes “steering bushes” on a 2018 Avensis, it usually means they’re actually talking about tie rods, control arm bushes, or sway bar bushes. That’s perfectly normal—and those are the items to check, service, and replace to keep the steering tight, safe, and roadworthy across Aussie and Kiwi conditions.

Popular questions about 2018 Toyota Avensis steering bushes

Does the 2018 Avensis have replaceable steering rack bushes?

No. The EPS rack on the 2018 Avensis is a sealed, integrated assembly. Toyota does not list separate rack-mount bushes as service parts. If there’s rack support play or noise, the official remedy is to replace the complete steering gear assembly. Most steering looseness complaints end up being tie rods, control arm bushes, or sway bar bushes rather than the rack body itself.

What should be checked if the steering feels loose or knocks?

Start with the easy wins: outer tie rod ends, then inner rack ends, followed by lower control arm bushes/ball joints and stabiliser links/D-bushes. Also check front strut top mounts, wheel bearings, tyre wear/pressures, and get a proper four‑wheel alignment. These are the known wear items that affect steering feel on the T27 Avensis.

Can aftermarket bushes be fitted to the Avensis steering rack?

Aftermarket suppliers generally don’t offer separate rack bushes for the 2018 Avensis EPS unit. Even if a universal bush appears to “fit”, it’s not recommended—EPS racks rely on precise housing alignment and NVH control. Toyota’s workshop guidance is to replace the complete rack if its internal supports are worn, and that’s the safe, roadworthy approach.
