Parts for your 2007 Toyota Bb-Strut mounts

2007 Toyota bB strut mounts — what they do and how to look after them

Based on Toyota’s technical literature, strut mounts are absolutely used on the 2007 Toyota bB. The Toyota New Car Features for the QNC2# bB platform states a MacPherson-strut front suspension, and the Toyota Electronic Parts Catalogue lists a “Front Suspension Support Sub‑Assembly” (strut top mount) and associated thrust bearing for this model. Prior bB/Scion xB manuals (NCP3#) show the same strut‑top arrangement, and the 2007 QNC‑series bB continues that concept. So, yes — strut mounts are relevant and fitted to the front of a 2007 Toyota bB.

On this bB, the strut mounts sit at the top of the front struts, tying the suspension into the body under the bonnet. They carry vehicle load, isolate vibration and road harshness, and provide a smooth, low‑friction pivot for steering. Good mounts keep the steering feel consistent, help tyres wear evenly, and cut down on knocks and creaks over bumps.

When they age, the rubber can crack or compress, and the thrust bearing can get notchy. Common tells include a clunk on slow speed bumps, a groan when turning the wheel at a standstill, woolly steering return, and feathered tyre wear. If you’re chasing vague on‑centre feel or a new rattle up front on your bB, the top mounts deserve a look.

• Inspection cadence: check every service from about 80,000–120,000 km onward, or sooner if the car cops a lot of rough roads. Include them in WOF/safety checks.
• Replacement approach: do both fronts together, fit OE or reputable aftermarket mounts, and replace any separate thrust bearings if the design uses them. New self‑locking nuts are a good idea.
• Workshop tips: use a quality spring compressor, mark strut and knuckle alignment, mind orientation arrows on the mount, torque with the suspension at normal ride height, finish with a wheel alignment.
• While you’re there: inspect front strut bearings, dust boots, bump stops and upper spring seats. Tired add‑ons can shorten the life of fresh mounts.

For most owners, fresh strut mounts restore that tidy, quiet front end feel the bB is known for, keeping steering light and predictable and tyres wearing nice and even across the tread. It’s a small bit of preventative maintenance that pays off in comfort and confidence on Aussie and Kiwi roads.

How often should 2007 Toyota bB strut mounts be replaced?

There’s no fixed interval, but many bB mounts last 100,000–180,000 km depending on roads and loads. Inspect at each service past 80,000 km. Replace at the first signs of cracking rubber, notchy steering, or clunks, and always get a wheel alignment after.

What are the symptoms of worn strut mounts on a 2007 Toyota bB?

Listen for a dull knock over speed humps, creaks when turning at low speed, and watch for twitchy or slow steering return. Uneven or feathered tyre wear and a slight change in ride height side‑to‑side can also point to tired mounts or bearings.

Does the rear of a 2007 Toyota bB have strut mounts too?

No — the rear uses a torsion beam with separate dampers and springs, so there aren’t rear “strut” mounts in the same sense. The rear has its own bushes and damper mounts that should be checked, but the classic strut top mount is a front‑only item on this model.
