Parts for your 2013 Toyota Bb-Sway bars & links

2013 Toyota bB sway bar links — what they do and how to look after them

Technical confirmation: The 2013 Toyota bB (QNC20/QNC21 series) is fitted with front sway bar (stabiliser) links. This is supported by Toyota’s Electronic Parts Catalogue (Suspension & Axle, Front Stabiliser section, which lists a “Link Assy, Front Stabiliser” for QNC20/21) and the Toyota Repair Manual procedures for “Front Suspension – Front Stabiliser Bar – Removal/Installation”, which show the link rods connecting the bar to the strut. Most 2013 bB trims use a rear torsion-beam without a separate rear sway bar link.

On this bB, the sway bar links (often called stabiliser links or swaybarslinks) are the small but mighty connectors that join the sway bar to the suspension. Their job is to keep the car flatter through corners, reduce body roll, and help the front tyres stay planted. When these links wear out, the driver may notice knocks over bumps, extra body lean, and a slightly “loose” feel in quick direction changes.

As part of regular servicing on a 2013 Toyota bB, it’s smart to check the sway bar links every 20,000–30,000 km or at each service if the vehicle sees rough roads. The ball-joint ends and bushes cop a fair hiding from Aussie and Kiwi roads, so a quick inspection can save a bigger bill later.

• Common signs they’re due: light clunks over speed humps, rattles on corrugations, uneven front tyre wear, or vague steering response.
• Workshop checks: look for torn dust boots, dry or cracked bushes, and play in the ball joints by levering the link while the suspension is loaded.
• Replacement tips: replace links in pairs left/right, torque fasteners with the vehicle at normal ride height, and consider new sway bar bushes if they’re perished.

Quality aftermarket or genuine links both do the job, but it pays to choose parts with good corrosion protection and OE-style ball joints. If the bB has been lowered or runs bigger wheels, the links can be under more stress, keep an ear out for new noises after suspension mods and recheck torque after a short run. A fresh set of sway bar links brings back that tidy, predictable turn-in the bB is known for, keeping the commute calm and the weekend run through the hills nicely controlled.

Popular questions about 2013 Toyota bB sway bar links

Do all 2013 Toyota bB models have rear sway bar links?

Most 2013 bB variants use a rear torsion-beam without a separate rear stabiliser bar, so there are usually no rear sway bar links fitted. The front definitely has stabiliser links, which do the heavy lifting for roll control in this platform.

How long do sway bar links last on a 2013 bB?

Driving conditions matter, but many owners see 60,000–120,000 km from the original links. Frequent gravel, potholes, or lowered suspension can shorten that. If there are knocks or extra roll, an inspection is worthwhile regardless of kilometres.

Can worn sway bar links fail a WOF or roadworthy?

Yes. Excessive play, damaged ball-joint boots, or loose hardware can lead to a fail. It’s a straightforward fix, and replacing both sides together helps restore balanced handling and keeps the inspector happy next visit.
