Parts for your 2008 Toyota Bb-Steering bushes

2008 Toyota bB Steering-Bushes

Based on Toyota’s factory repair literature and Electronic Parts Catalogue (EPC) for the QNC2# bB range (2005–2016), the 2008 Toyota bB uses rack-and-pinion steering with rubber rack mounting cushions (steering-bushes) and support bushes within the column assembly. So, steering-bushes are indeed fitted to this vehicle.

On a 2008 Toyota bB, steering-bushes do the quiet, hard work of isolating vibration and keeping the steering rack located precisely on the subframe. By cushioning the rack, they cut down on noise and harshness through the cabin while helping the wheels hold alignment under braking and cornering. That means sharper on-centre feel, more consistent tyre contact, and less kickback over corrugations and potholes—ideal for Aussie and Kiwi roads.

Over time, heat, age and oil contamination can harden or crack the rubber. When that happens, the rack can shift slightly under load and the steering feel goes a bit vague. Common tell-tales include:

• Clunks or knocks through the column on turn-in or over speed humps
• Wandering or tramlining, especially at highway speeds
• Uneven or accelerated tyre wear and a steering wheel that won’t stay dead straight
• Visible perishing or soft, oil-soaked bushes

As part of routine servicing, it’s smart to inspect the steering-bushes every 20,000–30,000 kilometres or at each WOF/rego check. A technician can gently lever the rack while a mate rocks the wheel to spot any excess movement. If replacement’s due, doing both rack bushes as a pair keeps the rack square. Torque the mounts at normal ride height, then book a wheel alignment. On EPS-equipped bB models, a steering angle zero-point calibration may be required after work—easy with the right scan tool.

Choosing bushes comes down to use. OE-style rubber keeps the ride quiet and comfy for daily commutes. Quality polyurethane options can sharpen feel and response if the bB sees spirited driving, though they’ll pass a touch more road texture into the cabin. Either way, avoid petroleum-based cleaners on the new parts, and never spin the steering wheel with the intermediate shaft disconnected—the clockspring under the steering wheel won’t thank you. While there, it pays to check tie rod ends and the intermediate shaft joints for play, so the whole front end behaves as one tight, tidy unit. Most workshops will knock over the job in about 1–2 hours.

Does the 2008 Toyota bB have steering-bushes?

Yes. The bB uses rubber mounting cushions (steering-bushes) to secure the steering rack to the subframe and additional support bushes in the column assembly. They’re essential for NVH control and rack alignment.

How often should steering-bushes be replaced on a 2008 bB?

There’s no fixed interval. Inspect them at regular services or every 20,000–30,000 km. Replace when there’s cracking, oil soak, excess rack movement, or symptoms like clunks and vague steering.

Rubber or polyurethane—what’s better for Aussie/NZ roads?

Rubber gives factory comfort and low noise, polyurethane offers a firmer, more direct feel. For mixed city–highway driving, rubber is great. For sharper response or heavier loads, a quality poly bush can be a good upgrade.
