Parts for your 2007 Toyota Bb-Strut mounts

2007 Toyota bB strut mounts — what they do and when to replace them

Technical sources confirm strut mounts are used on this model. Toyota’s bB Repair Manual for QNC20/QNC21/QNC25 (Front Suspension – MacPherson Strut) and the Toyota Electronic Parts Catalogue list a “Support sub-assembly, front suspension” (strut mount) for the 2007 Toyota bB. The front uses MacPherson struts with an upper mount and bearing, the rear is a torsion-beam with separate dampers, so no rear strut mounts are fitted.

On the 2007 bB, front strut mounts sit at the top of the strut, tying the strut to the body and isolating noise and vibration. Inside is a rubber insulator for comfort and, on the steering axle, a bearing that lets the strut rotate smoothly as the wheels turn. That mount helps hold alignment steady under load, keeps steering feel consistent, and soaks up harshness from rough Kiwi and Aussie roads.

There’s no fixed replacement interval, but as part of regular servicing the mounts should be inspected every 20,000 km and considered for renewal around 100,000–150,000 km, or sooner if symptoms show up. Many workshops replace mounts whenever new front struts or springs go in — it’s smart money, because the labour overlaps and fresh mounts protect the new dampers from extra stress.

• Common signs of worn strut mounts: clunks over bumps, notchy or heavy steering at low speed, a “memory steer” that doesn’t self-centre well, uneven front tyre wear, or visible perishing/cracks around the top mount.
• Best practice during replacement: renew mounts in pairs, choose OE-quality mounts with integrated bearings, fit new dust boots and bump stops, torque fasteners with the vehicle at ride height, and finish with a proper four-wheel alignment.

Owners of a 2007 Toyota bB will appreciate how much a healthy set of strut mounts sharpens steering and quietens the cabin. If there’s a persistent knock that isn’t fixed by sway-bar links or lower arm bushes, the top mounts are prime suspects. When the struts are out, always use a quality spring compressor and follow manufacturer torque specs. After fitting, expect steering to feel smoother with less kickback and the car to track straighter — small parts that make a big difference to daily comfort and control.

Popular questions about 2007 Toyota bB strut mounts

Do all four corners of a 2007 Toyota bB have strut mounts?
No. Technical documentation shows the bB runs MacPherson struts up front with strut mounts and bearings, while the rear uses a torsion-beam with separate dampers, so there are no rear strut mounts.

How long do front strut mounts last on a 2007 Toyota bB?
In normal Aussie and NZ driving, they often last 100,000–150,000 km. Rough roads, heavy loads or larger wheels can shorten that. Inspect at each service and replace with the front struts or when symptoms appear.

Are clunks and notchy steering always the strut mounts?
Not always. Sway-bar links, control-arm bushes, top strut nuts, or even worn struts can mimic the noise. If the steering binds or feels notchy at parking speeds, the mount bearing is a likely culprit, a proper inspection will pinpoint it.
