Parts for your 2010 Toyota Bb-Suspension bushes

2010 Toyota bB suspension bushes — what they are and when to sort them

Yes, the 2010 Toyota bB uses suspension bushes. Toyota’s own technical material for the bB QNC20/QNC21 platform (Front and Rear Suspension sections of the Toyota Repair Manual) and the Toyota Electronic Parts Catalogue list multiple bushes, including “BUSH, FRONT STABILIZER,” “BUSH, FRONT LOWER ARM,” and “BUSH, REAR AXLE BEAM/TRAILING ARM.” The layout is a MacPherson strut front end and a torsion‑beam rear, both of which rely on rubber bushes for location and vibration control.

On this bB, the bushes are the quiet achievers that keep things comfortable and tidy on Aussie and Kiwi roads. They isolate vibration, maintain alignment under braking and cornering, and help the steering feel planted. When they harden, crack, or flog out, you’ll often get clunks over bumps, vague steering, and uneven tyre wear.

As part of regular servicing, it’s worth inspecting the key bush locations:

• Front lower control arm bushes (front and rear positions)
• Front stabiliser (sway‑bar) D‑bushes and link bushes
• Rear torsion‑beam/trailing arm bushes

For a daily‑driven 2010 bB, bushes commonly last 80,000–150,000 km, but rough roads, oil contamination, or lowered suspension can shorten that. During a service, a visual check for perishing and a lever test for excessive movement will usually reveal issues. Any tearing, oil‑soaked rubber, or split sway‑bar D‑bushes is a green light for replacement.

When replacing, a few bB‑specific tips go a long way. Torque all arm and beam bolts at normal ride height to avoid preloading the new bushes. If a front lower arm rear bush is badly worn, many workshops fit a complete lower control arm rather than pressing a single bush — it can save time and ensures the ball joint is fresh too. Always book a wheel alignment afterwards, worn or new bushes will shift the geometry.

Choosing parts? Genuine‑style rubber keeps the ride quiet and comfy, perfect for city and highway work. Quality polyurethane can sharpen response and resist oil, but it will firm up NVH a touch. Either way, replace bushes in axle pairs and recheck fasteners after a few hundred kilometres. In NZ, a tired bush can fail a WOF, and in Australia it can knock you back at a roadworthy, so staying ahead of wear is well worth it.

Popular questions about 2010 Toyota bB suspension bushes

How do I know which bush is causing the knock on my bB?

A knock over sharp bumps often points to sway‑bar D‑bushes or links up front, while a dull thud and rear‑end steer sensation can be the rear torsion‑beam bushes. A workshop will load the suspension with a pry bar and check for movement, any free play or visible cracking is a giveaway. An alignment report showing big caster or toe changes also hints at control arm bush wear.

Do I need an alignment after replacing bB bushes?

Yes. Fresh bushes change the static position of the arms and beam, so toe and caster can shift. An alignment after any bush, arm, or beam work ensures even tyre wear and straight‑line stability. Ask the shop to torque fasteners at ride height before they align it.

Rubber or polyurethane bushes for a daily bB?

Rubber (OEM‑style) keeps NVH low and is ideal for commuting. Polyurethane sharpens steering and lasts well, handy if you drive spiritedly or carry loads, but expect a firmer feel over coarse chip. Many owners run rubber in the rear beam and consider poly just for the sway‑bar D‑bushes for a neat handling lift without much extra harshness.
