Front struts, lower arms and top mounts are sold by side and by suspension spec — standard, sport / lowered (S line, M Sport, R-Line, ST-Line etc.), heavy-duty and adaptive / electronic damping all use different part numbers, and some makers split by engine or front axle load. The references below are UK aftermarket catalogue listings for this generation, labelled by brand; genuine numbers are shown only where a listing quotes one. Confirm the fit against your VIN, and replace struts and top mounts in pairs.

A Genuinely Money-Saving Fix Worth Trying First — Toyota Prius Front Suspension

If you're hearing a muted "thump" or "pop" from the front suspension, particularly on rebound over speed humps, this is genuinely worth trying: one documented case saw exactly this noise resolved completely simply by lubricating the lower control arm bushes, which had dried out, rather than replacing any actual component — using a silicone-specific spray on the bushes.

A genuinely honest, real account worth knowing: one documented case saw drop links and anti-roll bar bushes replaced with zero improvement to a persistent clunk, only for the actual cause to turn out to be recently fitted brake pads rattling very slightly within the caliper — not a suspension fault at all.

It's also worth knowing that a clunk specifically over wide speed humps, but with no unusual noise on smaller bumps, has been documented on brand-new cars and can sometimes trace back to a subframe bolt not properly torqued at the factory.

Toyota Prius Front Suspension Strut: The System That Quietly Does All the Work

On the Toyota Prius, every pothole, bump and cornering load gets filtered through these parts long before it's felt inside the car, which is precisely why wear rarely shows up as one clean symptom. A methodical, process-of-elimination check tends to find the actual culprit much faster than guessing.

Before you buy: suspension components vary by trim, engine weight and whether your car has the standard or sport-tuned setup. Always confirm against your VIN before ordering.

Toyota Prius Front Suspension Strut: What It Does

The Toyota Prius's front struts fold two components into one: the damper and the coil spring's mount. A worn strut means the car keeps moving after a bump rather than settling promptly, and that lingering movement can accelerate uneven tyre wear over time.
