Parts for your 2016 Toyota Bb-Steering bushes

2016 Toyota bB steering bushes — what they do and when to replace

Based on Toyota technical sources, steering bushes are fitted to the 2016 Toyota bB. The Toyota Electronic Parts Catalogue for the QNC2# bB (P30 platform) lists “cushion, steering gear” components, and the Toyota Repair Manual (steering section) outlines removal and installation procedures that reference these mounting cushions. Even with the bB’s column‑assist electric power steering, the rack-and-pinion is secured to the front subframe using rubber bushes to control noise, vibration and harshness while keeping the rack located under load.

On this model, steering bushes isolate the steering rack from the body, soaking up road buzz while maintaining crisp steering feel. When they age or tear, the rack can shift a touch on the mounts, which shows up as a light clunk over bumps, vague on‑centre feel, or a thud on quick steering inputs. Left too long, it can speed up tyre wear and make the wheel tramline on coarse chip.

As part of regular servicing, it pays to have the bushes visually checked for cracking, oil swelling, or excessive rack movement. Many bB racks use bonded rubber cushions sized to the cradle, if they’re perished, replacement is straightforward with the rack loosened or removed, then a wheel alignment afterwards. Where polyurethane options are available, they can sharpen response but may pass a bit more road feel into the cabin — fine for keen drivers, less ideal if comfort is the priority.

Practical tips for the 2016 bB:

• Listen for dull knocks over speed humps and driveway lips.
• With the car safely raised, have a tech lever the rack gently to check for mount movement.
• Replace in pairs and torque the fasteners with the vehicle at ride height.
• Book a proper alignment after any steering bush work.

Service intervals aren’t mileage‑based for bushes, but a 60,000–80,000 km inspection rhythm works well in Aussie and Kiwi conditions. If the vehicle has seen fluid leaks onto the rack or lots of corrugations, bring that inspection forward. Fresh bushes restore the bB’s tidy, light steering feel and help keep tyres wearing evenly.

Popular questions

What are the symptoms of worn steering bushes on a 2016 Toyota bB?
Common signs include a dull clunk over small bumps, a slight shift or knock felt through the wheel on quick left‑right inputs, vague on‑centre feel, and accelerated or uneven tyre wear. On inspection, the rubber may look cracked, softened from oil exposure, or the rack may move on its mounts when levered.

How often should steering bushes be replaced?
There’s no fixed kilometre limit. In Australia and New Zealand, it’s smart to inspect them every 60,000–80,000 km or during any front‑end work. Replace when there’s visible deterioration or any play. Always follow up with a wheel alignment.

Can polyurethane bushes be used instead of rubber?
Yes, where available for the bB’s rack mounts, polyurethane can tighten steering feel and longevity. Expect a touch more road texture in the cabin compared to OEM rubber. For daily urban use, quality rubber suits most owners, for sharper response, polyurethane is a solid option.
